Several Li foil multi-wire proportional counters were constructed with five layers of 75 µm thick 6 Li foils spaced 1.63 cm apart. Each detector had 1250 cm 2 of active area and was backfilled with 1.0 atm of P-10 gas. Two of these detectors were po

A 550 cm 2 thermal neutron detector was constructed with five parallel sheets of 75 µm thick 6 Li foil (95% enrichment) spaced 1.63 cm apart. Anode wire banks containing a plurality of anode wires were strung on both sides of each foil, six banks in

Thin layers of LiF were deposited on a 2.0 µm thick aluminized BoPET (i.e. Mylar) in thicknesses of 4.5, 9.9, and 14.0 µm using an electron beam evaporator. These coatings were thinner than the summed triton and alpha particle range from the 6Li(n,

Water flow through a converging-diverging glass nozzle experiences a pressure drop and its velocity increases as it flows through the converging section. For an inviscid fluid, the pressure minimum occurs at the nozzle throat, where the cross-section

As a result of the recent shortage of 3 He for neutron detection, several new detectors have been proposed as viable alternatives. Thin-film coated diodes and boron-lined proportional counters are suggested options, but both suffer from the “wall-e

The recent shortage in the supply of 3 He for neutron detection has caused a large surge in research for a viable replacement. 6 Li has a large cross section for the absorption of thermal neutrons and emits two relatively short-ranged interaction pro
