24. Identifying and Resolving Shielding Issues

Mr Will Halcrow (STFC - ISIS)

01/12/2017, 11:20

In the latest instrument build programme at ISIS (TS2 Phase 2), two of the new neutron instruments suffered with significant radiation shielding problems. These problems slowed their commissioning, delayed their delivery and added cost to the projects. This presentation will give an overview of the radiation problems that were faced, and the challenges found whilst trying to characterize them....

3. In-Kind Instrument Projects – Gathering Experience by building an R&D guide-section.

Mr Sven Schuetz (PSI)

ESTIA will be one of the first instruments at ESS. Based on its elliptical Selene neutron guide concept, the Instrument will project a 0.06 x 1mm slit over a distance of 24m to the sample position (https://www.psi.ch/lns/estia). To achieve this extraordinary efficiency two Selene Guides will be aligned with 180 kinematic mounts. The mounts will spread over a length of 7.2m and will be...

12. Redesign of Monochromator Shielding of Cold Neutron Triple-Axis Spectrometer at HANARO

Mrs Ji-Myung Ryu (Korea atomic energy research institute)

01/12/2017, 12:00

A Cold Neutron Triple-Axis Spectrometer (Cold-TAS) was initially installed in the guide hall of HANARO’s cold neutron research facility in 2012. Owing to frequent mechanical troubles, simplification of the sample table and the analyzer took place in 2013. And the instrument was licensed for normal operation in 2014. Soon after, however, HANARO was shut down because of the reinforcement...

48. Manufacturability of Neutron Beam Monochromator Drum Shielding

Justin Jones (Merrick & Company)

01/12/2017, 12:20

To obtain the precision required for custom instruments used in neutron facilities, it is necessary to consider materials and components and their effect on tolerances throughout the entire design, manufacturing, and installation process. Designing for manufacturability includes considering and minimizing the number of components in an assembly; the stack-up of tolerances; the effects of...
