The Central Drift Chamber (CDC )\, one of the detectors\, measures the trajectory and determines the mome ntum of charged particles using its front-end readout module. The detector system has led to many physics results recently\, but also revealed opera tional issues.

There are now numerous projects to search fo r weakly coupled bosons\, including the X17\, using particle physics exper iments . However\, only the ATOMKI group have utilized nuclear reac tions in a competitive way to date.\n\nWe intended to employ the Pelletron accelerator in Melbourne to initiate nuclear reactions of the kind: p+ZX →Z+1Y +( e+e−) and to build a low mass\, high precision Time Projectio n Chamber\, (TPC) with world-first capabilities. The invariant mass resolu tion of the TPC to the (e+e−) final state is expected to be 0.1 MeV. Thi s provides a substantially more sensitive search for anomalous (e+e−) pr oduction than any other experiment and 200 times more sensitivity than ATO MKI. Accordingly\, we will either observe the ATOMKI anomaly on the Pellet ron or exclude it at very high significance. Following this we propose a p rogram to search for anomalous (e+e−) production with world-leading sens itivity in the 5-25 MeV mass region. In addition\, the very large accepta nce\, and excellent angular and energy resolution of the TPC enables quali tatively more sensitive investigations of Nuclear Internal Pair Conversion decays. This capability enables a range of novel Nuclear Physics investig ations.\n\nThe presentation will describe the proposed TPC\, its expected performance together with its application and anticipated impact in partic le and nuclear physics investigations.\n\nhttps://events01.synchrotron.org .au/event/169/contributions/5161/ LOCATION: Room 1 URL:https://events01.synchrotron.org.au/event/169/contributions/5161/ END:VEVENT BEGIN:VEVENT SUMMARY:PandaX-4T: A Multi-Ton Liquid Xenon Detector for Dark Matter and N eutrino Physics DTSTART;VALUE=DATE-TIME:20230413T014000Z DTEND;VALUE=DATE-TIME:20230413T020000Z DTSTAMP;VALUE=DATE-TIME:20260813T181205Z UID:indico-contribution-169-5128@events01.synchrotron.org.au DESCRIPTION:Speakers: Xiangyi Cui (Shanghai Jiao Tong University)\nDark ma tter\, a new non-luminous matter which is induced from the astronomical ob servation\, play a leading role in the universe component.

Benefitting from μm-scale dimensions of the plasma wakefiel d\, the electron beams and x-ray sources driven by LWFA are naturally feat ured few-femtosecond (fs) duration\, μm-level transverse size and high br ightness. With the intensive development of LWFA in the past two decades\, key principles and advanced concepts to generate electron beams with GeVs energy\, low emittance and kiloampere peak current have been verified\, a nd phase-contrast imaging\, computed tomography and ultrafast x-ray absorp tion spectroscopy performed with betatron sources and all-optical inverse Compton scattering sources have been demonstrated. These results show that LWFA is capable of becoming a competitive candidate for the next generati on compact light sources and electron-positron colliders. \nLWFA is sensit ive to temperature\, humidity and cleanliness. Temperature fluctuation cau ses mechanical deformation of optomechanical components\, resulting in the pointing jitter and quality deterioration of laser beams. Humidity fluctu ation and poor cleanliness cause optical surface contamination\, even dama ge the optical mirrors\, lenses and crystals. To date\, general LWFA syste ms are almost installed in fixed laboratories or facilities with relativel y large scales to meet the operation requirements of a clean environment w ith constant temperature and humidity. It is still a major challenge for L WFA to operate reliably\, steadily and flexibly in a complicated environme nt for different application scenarios.\nHere\, we have developed a real t able-top LWFA based ultrafast synchrotron radiation source having a size o f 1.5m×3m. The apparatus\, consisting of an industry level compact 40TW T i:Sapphire laser (also developed by ourselves) and a compact vacuum system capable of 10Hz repetition frequency\, has been proved to have a capacity of continuous and stable operation for a few days. Utilizing the table-to p synchrotron radiation source\, high resolution images and computed tomog raphy of biological and industrial specimens with a 10μm-level resolution are obtained.

After a century of studies\, it is only recently that sufficiently high electromagnetic field strengths have been available to experimentall y study the nonlinear regime of the scattering in the laboratory. This can act as a new generation of accelerator-based hard X/γ-ray sources driven exclusively by laser light. One ultrahigh intense CPA laser pulses will a ct as two means: first used to accelerate electrons by laser driven wake f ield (LWFA) to hundreds MeV\, and second\, from split beam or LWFA-leftove r energy reflected by plasma mirror\, to collide on the electron for the g eneration of X/γ-rays. Such all-laser-driven X/γ source have recently be en demonstrated to be energetic\, tunable\, narrow/broad in bandwidth\, sh ort pulsed and well collimated. Such characteristics\, especially from a c ompact source\, are highly advantageous for numerous advanced X-ray applic ations. Moreover\, the scattering interaction can act a test bed for high- field QED study.

This requires modulation of x-ray intensity in space and/or time. Typically\, this is ac hieved using a multi leaf collimator (MLC) — a complex mechatronic devic e comprising over one hundred individually powered tungsten ‘leaves’ t hat move in or out of the radiation field as required. Here\, an all-elect ronic x-ray collimation concept with no moving parts is presented\, termed “SPHINX”: Scanning Pencil-beam High-speed Intensity-modulated X-ray s ource. SPHINX utilizes a spatially distributed bremsstrahlung target and c ollimator array in conjunction with magnetic scanning of a high energy ele ctron beam to generate a plurality of small x-ray “beamlets.”\n\nMetho ds: \n\nA parametric simulation environment was developed in Topas Monte C arlo enabling simulation of a SPHINX structure from linac phase space to d ose in water tank including transport through scanning magnets. The SPHINX geometry was parameterized with 8 variables\, which were optimized using Bayesian optimization. The goal of the optimization was to maximize dose r ate for a user input beamlet width without violating physical geometric co nstraints. Designs for beamlet widths of 5\, 7\, and 10 mm were generated\ , with 200 iterations run for each model. For the seven-mm design\, a simu lation of dose in water for a 50x50 mm square field was carried out\, inc orporating transport through custom scanning magnets. \n\nResults: \n\nThe Dose per charge was 3574\, 6351\, and 10015 Gy/C for the five\, seven\, a nd ten mm models respectively. \n\nConclusions:\n\nSPHINX designs for user -input beamlet widths were generated using Bayesian Optimisation of topas monte carlo simulations.\n\nhttps://events01.synchrotron.org.au/event/169/ contributions/5189/ LOCATION: Room 1 URL:https://events01.synchrotron.org.au/event/169/contributions/5189/ END:VEVENT BEGIN:VEVENT SUMMARY:Feasibility study of the Polarization control of synchrotron radia tion in NSRRC DTSTART;VALUE=DATE-TIME:20230413T052000Z DTEND;VALUE=DATE-TIME:20230413T054000Z DTSTAMP;VALUE=DATE-TIME:20260813T181205Z UID:indico-contribution-169-5188@events01.synchrotron.org.au DESCRIPTION:Speakers: T.

On this basis\, CSNS plans to increase the average beam power to 200 k W\, which is to double the current strength of the circulating beam of RCS \, with the injection energy unchanged. The main means is to add a second harmonic RF cavity to the RCS.\n\nThe space charge effect is an important factor to limit the current intensity in high power particle accelerators\ , especially for low- and middle-energy proton synchrotrons. In order to r educe emittance increase and beam loss caused by space charge effect\, CSN S has added a magnetic alloy cavity in 2022 summer to provide a second har monic RF cavity with harmonic number of 4\, and form a dual harmonic RF sy stem together with the original cavity with harmonic number of 2\, so as t o optimize the longitudinal beam distribution.\n\nThis talk will focus on the beam commisioning and simulation results after the installation of mag netic alloy cavity.\n\nhttps://events01.synchrotron.org.au/event/169/contr ibutions/5160/ LOCATION: URL:https://events01.synchrotron.org.au/event/169/contributions/5160/ END:VEVENT BEGIN:VEVENT SUMMARY:Laser-plasma schemes of narrowband THz emission for THz electron a cceleration DTSTART;VALUE=DATE-TIME:20230413T042000Z DTEND;VALUE=DATE-TIME:20230413T044000Z DTSTAMP;VALUE=DATE-TIME:20260813T181205Z UID:indico-contribution-169-5163@events01.synchrotron.org.au DESCRIPTION:Speakers: MinSup Hur (UNIST)\nOne promising method to overcome the vacuum-breakdown limitation in conventional RF-linacs is to use high- frequency fields such as terahertz radiation. To be useful in accelerators \, narrowband sources of THz emission are preferable since they can focus more energy into the desired band that fits the accelerating tube. However \, laser-plasma-based THz schemes currently available are generally wideba nd and generate only a few-cycle pulses\, even though they are efficient a t generating strong peak fields. The system efficiency is\, therefore\, lo w since only a selected band from the emission is used for acceleration. I n this talk\, I present several new ideas that can generate quasi-narrowba nd THz emission from laser-driven plasmas. One idea involves using plasma- dipole-oscillation\, which routinely yields a very narrow spectrum of THz with an efficiency of more than 0.1%. Another idea involves concentrating the THz spectrum around the beat frequency of two driving laser pulses. Ov erall\, this talk focuses on the development of more efficient and effecti ve methods for generating narrowband THz emission from laser-driven plasma s\, which could potentially improve the efficiency of THz-based accelerato rs and other applications requiring high-energy terahertz radiation.\n\nht tps://events01.synchrotron.org.au/event/169/contributions/5163/ LOCATION: URL:https://events01.synchrotron.org.au/event/169/contributions/5163/ END:VEVENT BEGIN:VEVENT SUMMARY:Generation and Application of High Energy Electron Beams and Hard- X-rays from Laser Wakefield Accelerator.

The typical example is radioac tive isotopes 10Be and 10B that are used to date geological objects at a t ime scale of one million years. To solve this problem\, a new ion identifi cation technique\, namely that based on measuring both ion track ranges an d ion energies in low-pressure TPCs with GEM readout\, has been developed. This technique is proposed to be applied in AMS for dating geological ob jects\, namely for geochronology of Cenozoic era. We developed the TPC wit h a dedicated thin silicon nitride window for an efficient passage of ions . The TPC characteristics were studied in isobutane at low pressures using alpha particles of different energies. Based on these data and SRIM code simulation\, it was shown that it is possible to efficiently separate isob aric boron and beryllium ions at a nominal pressure (50 torr).

VIT A is the part of accelerator based (AB) neutron source in which protons/de utrons with an energy in range from 0.3 to 2.3 MeV and current in range fr om 1 nA to 10 mA are transported to a lithium or another target. It result s in generating neutrons with a wide range of energies – cold\, thermal\ , epithermal\, fast.\nIndustrial applications of the VITA are: quafilicati on and testing perspective materials for thermonuclear fusion\, investigat ions of metal blistering and measuring of cross-sections of nuclear reacti ons.\nMedical applications of the VITA are: investigations in BNCT\, condu cting BNCT on domestic animals. VITA became a prototype for the AB neutron source in Xiamen (China)\, which is now in clinical trials\, and for the AB neutron source for N.N. Blokhin Oncology Center (Moscow\, Russia).\nIn talk there will be given details about VITA and industrial and medical app lications of the VITA.\nThis work was supported by the Russian Science Fou ndation (grant number 19–72-30005).\n\nhttps://events01.synchrotron.org. au/event/169/contributions/5151/ LOCATION: Room 1 URL:https://events01.synchrotron.org.au/event/169/contributions/5151/ END:VEVENT BEGIN:VEVENT SUMMARY:Development of high power irradiation accelerators in China DTSTART;VALUE=DATE-TIME:20230412T042000Z DTEND;VALUE=DATE-TIME:20230412T044000Z DTSTAMP;VALUE=DATE-TIME:20260813T181205Z UID:indico-contribution-169-5145@events01.synchrotron.org.au DESCRIPTION:Speakers: JIaru Shi (Tsinghua University)\nIrradiation acceler ator use high power electron beam in the application of processing of food \, medical product\, quarantine treatments.

Especially for BNCT applications\, the abi lity to suppress unwanted radiation to patients is a major advantage. Howe ver\, it is difficult to supply a high-intensity lithium-ion beam\, and it s practical application has been considered impossible. Therefore\, to sol ve the most important issue\, the lack of ion flux\, a direct plasma injec tion method was adopted. In this method\, pulsed high-density plasma from a metallic lithium foil generated by laser ablation is efficiently injecte d and accelerated by a radio-frequency quadrupole linear accelerator (RFQ linac). As a result\, a peak beam current of 35 mA\, accelerated to 1.43 M eV\, which is two orders of magnitude higher than the conventional injecti on/accelerator system\, can be obtained.\n\nhttps://events01.synchrotron.o rg.au/event/169/contributions/5132/ LOCATION: Room 1 URL:https://events01.synchrotron.org.au/event/169/contributions/5132/ END:VEVENT BEGIN:VEVENT SUMMARY:Radiotherapy LINAC Breakdowns in Low- and Middle-Income Countries DTSTART;VALUE=DATE-TIME:20230413T000000Z DTEND;VALUE=DATE-TIME:20230413T002000Z DTSTAMP;VALUE=DATE-TIME:20260813T181205Z UID:indico-contribution-169-5150@events01.synchrotron.org.au DESCRIPTION:Speakers: Greg Peiris (The University of Melbourne)\nAccess to Radiotherapy Linear Accelerators (LINACs) remains a significant challenge in Low and Middle-Income Countries (LMICs) for effective cancer treatment . The complexity of LINACs is further compounded in LMICs by environmental \, socio-economic\, and geographical factors\, resulting in frequent break downs\, with downtimes lasting from days to months. Recent studies have id entified the Multi-Leaf Collimator (MLC) subsystem as having a disproporti onate failure rate\, especially in LMICs\, which calls for re-evaluation. Through an analysis of Indonesian facilities\, we provide insight into the causes of downtime and failure pathways for RT LINACs in LMICs. We also s how that MLC accounts for 59% of all mechanical faults in LINACs\, with do wntime being 7 times longer in LMICs than in High-Income Countries (HICs). Further analysis of MLC leaf width demonstrates that narrow 5mm leaves co ntribute to 18.27±6.5% of all breakdowns\, while wider 10mm leaves make u p 15.87±4.3%. These findings highlight the need to review the current gen eration of Radiotherapy LINACs and design future models that are more robu st and suitable for all environments.\n\nhttps://events01.synchrotron.org. au/event/169/contributions/5150/ LOCATION: Room 1 URL:https://events01.synchrotron.org.au/event/169/contributions/5150/ END:VEVENT BEGIN:VEVENT SUMMARY:Materials science research at Indus beamlines DTSTART;VALUE=DATE-TIME:20230413T012000Z DTEND;VALUE=DATE-TIME:20230413T014000Z DTSTAMP;VALUE=DATE-TIME:20260813T181205Z UID:indico-contribution-169-5155@events01.synchrotron.org.au DESCRIPTION:Speakers: Tapas Ganguli (Raja Ramanna Centre for Advanced Tech nology)\nIndus 1 and Indus-2 are India's only two synchrotron radiation so urces\, designed and developed in India. Both these machines were designed in the early 1990s\, with Indus-1 being operational since 1999 and Indus- 2 was operational since 2005. Indus-2 is a 2.5 GeV\, 200 mA machine\, and Indus-1 is a 450 MeV\, 125 mA machine. Currently\, Indus-2 has 18 operatio nal beamlines\, out of which 16 are for users and 2 beamlines are specific ally designed for machine diagnostics. Indus-1 has 7 operational be amlines. These beamlines have attracted a large number of users from the I ndian academia and industries over the last several years and currently ov er 950 user experiments of carried out annually with about 175+ publicatio ns in peer reviewed international journals from the work carried out at In dus beamlines. Among the operational beamlines\, 2 beamlines\, namely\, An gle Resolved Photo Electron Spectroscopy beamline and X-ray Magnetic Circu lar Dichroism beamline\, are designed and operated on insertion devices\, and the remaining beamlines of Indus-2 are designed on bending magnets. 7 more beamlines (out of which 3 are on insertion devices) are in various s tages of development. Materials research in general\, has been the primary area of interest among the user community at Indus\, although in recent y ears\, the protein crystallography community and the Indian pharmaceutical industry has also been using these facilities extensively. Experiments re lated to projects of national importance like the Indian Space Research Or ganization's (ISRO) lunar missions\, Chandrayaan-1 and Chandrayaan-2 have also been carried out at Indus. In the talk\, some of the details of these beamlines and a few important results based on experiments carried out at Indus in the last few years\, will be presented.\n\nhttps://events01.sync hrotron.org.au/event/169/contributions/5155/ LOCATION: Room 1 URL:https://events01.synchrotron.org.au/event/169/contributions/5155/ END:VEVENT BEGIN:VEVENT SUMMARY:Experiences with new Insertion devices at the Australian Synchrotr on DTSTART;VALUE=DATE-TIME:20230413T040000Z DTEND;VALUE=DATE-TIME:20230413T042000Z DTSTAMP;VALUE=DATE-TIME:20260813T181205Z UID:indico-contribution-169-5124@events01.synchrotron.org.au DESCRIPTION:Speakers: Eugene Tan ()\nTBC\n\nhttps://events01.synchrotron.o rg.au/event/169/contributions/5124/ LOCATION: URL:https://events01.synchrotron.org.au/event/169/contributions/5124/ END:VEVENT END:VCALENDAR
