Abstract

A helical cathode proportional chamber for the end counter of two dimensional drift chambers is described. The sensitive volume is 1

2×1.2×10cm

. The energy loss ΔE resolution of 12.1% and space resolution of 1.2mm (FWHM) were obtained for 5.3 MeV α-particles (ΔE~1MeV) with 90% argon and 10% CH

mixture at a pressure of 730 torr.
