Data hitches a rides on fast neutrons

Enginees at Lancaster University have transmitted, received and decoded data sent over a fast neutron stream. The proof-of-concept involved modulating neutrons from a calfornium 252 source using an Arduino-controlled mechanical shutter built from high-density polythene. Detection involved a one litre tank of scintillating meterial, a photo-multiplier and a ‘mixed-field analyser’ (made by Hybrid Instruments, based at ...
