Description
The Solid-State Neutron Detector, SoNDe [1], is a position-sensitive thermal-neutron detector for highflux
sources currently being developed for the upcoming European Spallation Source (ESS). In this
study, a SoNDe detector coupled to a 6Li-glass scintillator was investigated at the R2D2 beamline at the
Institute for Energy Technology in Oslo, Norway.
For the tests, the GS20 6Li-glass scintillator was dry-fitted on a Hamamatsu H12700 multi-anode
photomultiplier tube (MAPMT). The MAPMT was connected to a SoNDe readout module. The system
was operated in three modes: event-by-event pulse height for all pixels, event-by-event pulse height for
the triggering pixel and using the timestamp and pixel ID for each trigger. Data from the three operating
modes were acquired using IDEAS Testbench [2] and the ESS Data Management & Software Center's
Event Formation Unit (EFU) [3]. Pixel-to-pixel crosstalk was investigated as well as steps towards
neutron-position sensitivity and count-rate capability were taken. Preliminary results will be presented.
