An All Epitaxial Silicon Diode Heavy Ion Detector

An all epitaxial silicon diode (ESD) heavy ion detector has been designed, fabricated, and tested. The active area of the detector is 5 cm2 and has a total thickness of 50 μ. The response of the detector has been studied with fission fragments, alpha particles, oxygen ions, and sulfur ions. A number of advantages in terms of both fabrication and performance are discussed.
