A modular large-area lithium foil multi-wire proportional counter neutron detector

Operational properties of fine powder aerosol as radiation detection medium in gaseous proportional counters

“…Since the scientific community became aware of the 3 He shortage crises, research and development on 3 He-free neutron detection solutions became a priority and innovative alternatives are being developed. A variety of techniques have been reported, including boron-lined detectors coupled to multi-wire proportional counters (MWPC) [9,10] and to gas electron multipliers (GEM) [11,12], arrays of boron-coated straws [13][14][15], aerogel and saturated foam detectors [16][17][18], scintillators [19,20], suspended lithium foils coupled to MWPC [21][22][23] and lithium backfilled microstructures [24,25].…”
