摘要：

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 Ar-40 at 95 A MeV with an intensity as high as 10(6) cps. (C) 2004 Elsevier B.V. All rights reserved.
