Abstract
The operation of a xenon filled gas proportional scintillation counter unde
r low charge multiplication gains is discussed. It is shown that the best e
nergy resolution for X-rays is obtained for a reduced electric field, E/p,
of about 8 V cm(-1) Torr(-1), leading to a charge gain (for inter-grid dist
ance of 5 mm) of about 1.05, as calculated by a Monte Carlo simulation meth
od. A discussion is presented concerning the dependence of the E/p values f
or better detector performance, on the inter-grid distance. (C) 1999 Elsevi
