Strip Detector For Short-Range Particles

Conference Paper


Abstract


  • A silicon strip detector for the coordinate determination of the short range charged particles, particularly heavy ions, has been developed and investigated. The detector had 28 p+n strips made by ion implantation, the pitch was 250µm, the interstrip distance was 50µm. The coordinates of particles incident between adjacent strips were determined by two-dimensional amplitude analysis of the charges collected on neighboring strips. Irradiation with a-particles of 226Ra and scanning laser beam was used. The coordinate determination accuracy better than 1µm was obtained. In contrast to minimum ionized particle the plasma tracks of short range particles have higher carrier densities and are located in inhomogeneity region of the detector. The study of the charge collection times have. indicated the essential role of the drift of charges in inhomogeneous electrical field dependent of the detector geometry, inhomogeneity of silicon and built-in charge in passivating oxide layer between p+n strips. © 1992 IEEE.
