A new two-dimensional scintillation detector system for small angle neutron scattering experiments
A new two-dimensional position-sensitive detector system for small-angle neutron scattering experiments is under development. It is based on a 60 x 60 cm(2) large Li-6-glass scintillator for the neutron capture and dispersion of the emitted light on an array of photomultiplier tubes for the derivati...

A new two-dimensional position-sensitive detector system for small-angle neutron scattering experiments is under development. It is based on a 60 x 60 cm(2) large Li-6-glass scintillator for the neutron capture and dispersion of the emitted light on an array of photomultiplier tubes for the derivation of the event position. For subthermal neutrons of 8 Angstrom, an efficiency of 96% and a spatial resolution of 8 mm are to be achieved. Major improvements have been made in the signal- and data-processing branch, which aims at an electronical dead time of 1 mus. A fast digitalization method using free-running analog-to-digital converters for each photomultiplier combined with field-programmable gate arrays for a parallel event detection in all channels has been applied. A subsequent farm of up to 16 floating-point digital signal processors is used to provide enough computing power for an improved reconstruction of the event position according to a maximum likelihood method. |
