Abstract
We have developed a delay-line parallel-plate avalanche counter (PPAC) with high detection efficiency for high-energy light ions. A large signal-to-no ise ratio was achieved by a newly designed pre-amplifier and the usage of C 3F8 gas at a pressure of 30 Torr. The counter has been tested with beams of 90 A MeV (7) Li at RIKEN, 340 A MeV (12) C at GSI, and 254 A MeV B-8 at GS I. We achieved high detection efficiencies (> 95%) for all of these ions. F urthermore, we achieved reasonable position and timing resolutions. (C) 200 1 Elsevier Science B.V. All rights reserved.
