How IN16 can maintain a world-leading position in neutron backscattering spectrometry

摘要

IN16 will be upgraded within the ILL Millenium program. We present briefly the concepts which will ensure that the extremely successful backscattering spectrometer IN16 maintains its leading position. The most important component is a phase space transformation (PST) chopper for which the spectrometer has to be placed on ail end-of-guide position. We summarize first simulation results for the two guide positions in question, based oil simulations of the source, guide, selector, focusing guide, PST and Doppler monochromator arrangement.
