Abstract
wThe long-term performance of a Delta E gas counter filled with P-10 g as at a pressure of 130 Torr, and operated in the proportional mode, i s monitored. The presence of iron-oxide based catalysts within the cou nter volume successfully removes electronegative impurities from outga ssing and initial contaminants. It has been possible to operate this c ounter continuously for more than three months, with good resolution ( 9-10%). The initial slow decrease of peak channel with time has been a ttributed to the dynamic increase of electronegative impurities. It ha s been concluded that the long-term performance of a gas counter depen ds substantially on the concentration of the catalysts. (C) 1998 Elsev ier Science B.V. All rights reserved.
