- Abstract
- The PHENIX MPC-EX is an W/Si pre-shower detector operating at small angles with respectto the beam in the Relativistic Heavy Ion Collider (RHIC). The Si Mini-Pad sensors are the activeelement of the detector. The expected hadron flux to the Si Mini-Pad sensors will generate significantnon-ionizing energy loss in the sensors, which may damage the crystalline structure of thesensor’s bulk material. We investigated the nature of the hadron flux to the Si Mini-Pad sensorsthrough a full simulation and determined its effect on the sensor’s characteristics based on a beamtest. The investigation showed key issues in designing a preshower detector using silicon sensorsand operating under a large neutron fluence and offered valuable information on the operation ofthe MPC-EX detector.
