    "abstract": "A new multiwire proportional chamber (MWPC) was designed and constructed for\nprecision studies of neutron beta decay angular correlations. Its design has\nseveral novel features, including the use of low pressure neopentane as the\nMWPC gas and an entrance window made of thin Mylar sheet reinforced with Kevlar\nfibers. In the initial off-line performance tests, the gas gain of neopentane\nand the position resolution were studied.",
