Pressurized multiwire proportional chamber for neutron imaging
Description
A pressurizable neutron-sensitive multi-wire proportional chamber has been constructed to test the effect of increased gas density on image resolution. The chamber has dimensions of 25 cm x 25 cm and is pressurizable to 4 atm. With a single-plate converter the thermal-neutron detection efficiency was 6.3 percent for gadolinium and 2.3 percent for boron-10. For a four-fold increase in chamber pressure the overall resolution improved more than a factor of two for boron, but relatively little for gadolinium. The effects of cathode biasing is also discussed
