IMPS (Imaging MultiPlexed Spectrometer)
IMPS (Imaging MultiPlexed Spectrometer) is a multi-analyser detector system for the thermal TAS IN8.
It is intended for imaging the (Q,ω) space. Its design makes it compatible with the classical TAS configuration.
Its strong points are :
- Gain in instrumental flexibility
- Gain in count rate of factor 2-3
