A Neutron Spin-Echo Spectrometer (NSE) measures small velocity changes at a sample of the neutrons encoded by the neutrons spin clock while the neutron spin precesses in large magnetic fields following Bloch's equation. In order to reach this ambitious goal, a high precision of the magnetic field integral before and after the sample, which directly relates to the resolution of the...

On 3 July 2017 ANSTO went live with a major new system known as SAP Ae (Ansto Enterprise). This one stop shop covers all aspects of asset management planning, including procurement, maintenance, calibration, asset renewal, customer relationships and even HR. This system has been primarily designed for the commercial side of ANSTO (Nuclear Medicines, Silicon Irradiation and Minerals divisions)....

Neutron Guides & Shielding
Oral Presentation
As part of the transfer of the BioRef instrument from Helmholtz Zentrum Berlin (HZB) to ANSTO, Sydney, a number of lead shielding components will need to be lifted in and out of their positions. These lifts utilise RAMPA Type B inserts embedded in the lead shielding via a self-tapping process with a pilot hole. These inserts have been used extensively at other facilities and there is data on...

Safety Interlock System and User Interfaces
My poster will be on the safety interlock system (SIS) employed at the ACNS, focusing on the interfaces including the touch screens we use to operate the safety system for an instrument.
The touch screen interface design satisfies the needs of various users:
1. Instrument users require very clear and basic instructions to operate the...

During the 2019 major shutdown, ANSTO has set up a project to remove existing Thermal Neutron Guide (TG1-3) in-pile assembly and replace it with a new in-pile assembly containing an additional TG-2 A/B in-pile guides.
The purpose of this presentation is to provide following:
- Brief description of ANSTO neutron guide configuration;
- Improvements made to enable easier future guide...

Neutron Guides & Shielding
Poster
Higher background on detectors compared to anticipated design levels? Persistent hot spots on detectors? Increased radiation levels? These are common aspects of a new instrument, and even an old instrument. The divergent beam exiting from a guide, or reflecting from a chopper, can create unwanted background, or damage neighbouring equipment.
For instance, persistent hot spots and higher...

The backscattering instrument managed by ANSTO called Emu was built with two neutron choppers. These choppers condition the neutron beam and typically spin at 2400rpm and 1200rpm respectively. They were supplied with an integrated vibration monitoring system. From late 2016, this system would occasionally trip, decreasing the availability of the instrument. This issue, coupled with the...

Materials and Life Science Experimental Facility (MLF) at J-PARC is a pulsed neutron facility. The accelerators have delivered a proton beam at 25 pps to a mercury neutron producing target. MLF has over 20 instruments and over 50 neutron choppers.
Neutron Choppers are important devices that remove unwanted energy components from the pulsed neutron beam. We have been improving durability and...

Neutron radiography has been conducted at the SAFARI-1 research reactor since the early 1970’s. Digital neutron radiography commenced in 1996 and a 3D tomography capability was installed in 2003. Major deficiencies regarding corrosion of water cooling pipes of the internal collimator as well as shielding and control infrastructure were identified to be addressed in the design of new...

ANSTO is planning to replace the Cold Neutron Source (CNS) at the end of its design life. The project has a number of challenges due to the activity of the components. Working to ALARA principles and to minimise the reactor shutdown duration, a number of specialised tools and processes are being developed.
The topics that will be discussed in this presentation include the components to be...

In order to complete and complement the neutron instruments, Australian Centre for Neutron Scattering procures and commissions a continuously evolving suite of sample environment equipment, able to determine and manipulate the physical conditions under which a neutron scattering experiment is performed. The sample environment equipment, therefore, plays a crucial role in the success of an...

Neutron beam polarization devices
Oral Presentation
The neutron reflectometer MARIA with polarization analysis is dedicated for the investigation of thin interfaces like magnetic layered structures down to the monolayer scale and/or lateral structures. To maximize the signal to noise ratio the background scattering has to be kept as low as possible. Therefore the flight path of the neutrons before and after the sample should be not in air but...

Neutron supply for research is nowadays predominately based on spallation or fission. The High Brilliance neutron Source (HBS), currently under development at Forschungszentrum Jülich, will use protons or deuterons from an accelerator in the 10 MeV to 50 MeV range, shot on a low Z-material in order to produce neutrons. The HBS is optimized to be highly cost efficient and scalable. Medium flux...
