A hybrid streamer chamber for intermediate energy heavy ions physics

Abstract A small volume streamer chamber currently in use at the Lawrence Berkeley Laboratory 88″ cyclotron is described. A series of external solid state telescopes serves both as the event trigger, and to record the energy and particle identification of the leading fragment in the reaction. The application of this device to the study of associated charged particle multiplicities in reactions of 16 O+CsI at 16.5 MeV/nucleon is presented to illustrate its capability.
