From: Detector development for spin-echo SANS techniques using ZnS:Ag/6LiF and 6Li glass scintillators

Sketch of the position sensitive WLSF ZnS:Ag/6LiF scintillator-based detector. The fibre array consists of 64 fibres (0.5 mm \(\oslash\) 0.6 mm pitch) sandwiched between two scintillator sheets (0.25 mm and 0.45 mm thick) and aluminium optical masks with 0.2 mm openings on a 0.6 mm pitch. A 5 mm B4C plate to reduce neutron background is placed behind the second scintillator. Pictures on the right show the detector size and geometry of the final assembly.
