A parallel plate avalanche detector system for the localization of relativistic heavy ions

Abstract

Parallel plate avalanche counters have been designed and used for localization of relativistic heavy ions. They have been tested alpha particles from a ²⁴¹Am source. They have been used with the heavy-ion beams from Saturne in conjunction with the 4π detector Diogene. They provide an accurate measurement of the vertex position with eficiency.
