Proton Low Gain Avalanche Detector (pLGAD) for Low Energy Particles Detection

Abstract

In this work, we present the pLGAD concept, which is based on the LGAD technology developed at IMB-CNM. We describe the main characteristics of this novel detector suitable for low energy particles detection. Using 2D TCAD numerical simulations we optimize its multiplication region characteristics, the VBD-Gain trade-off and the periphery design. Also, we define a first pLGAD fabrication run to integrate it at IMB-CNM clean room. Moreover, we describe the first n-type LGAD prototype.
