✦ Synopsis
A high-rate particle identification device for high-energy heavy ions has been developed which utilizes a stacked configuration of grid-less parallel plate gas ionization chambers with thin anode-cathode gaps. The high-rate capability of this chamber was realized by adopting bipolar shaping of anode signals and by the suitable choice of a counter gas. Z-resolutions of 0.2-0.3 were obtained for nuclear fragments of 40 Ar at 95 A MeV with an intensity as high as 10 6 cps:
