Abstract

Based on the advantages silicon drift detector (SDD) and avalanche photo diode (APD), a droplet-like avalanche drift diode detector (DADD) is proposed. Firstly, the overall structure of the DADD has been designed considering the parameters of bow-shaped curves, distance of drift ring, extra biased voltage and width of drift ring. Secondly, the surface potential of DADD has been simulated and obtained the relation of dark current of drift ring and voltage drops between different drift rings. In addition, static structure analysis and steady state thermal analysis have been implemented. The simulation results show that, the DADD has a good structure and features with high gain, smaller output capacitance and high photon counting capacity, which is appropriate for the pulsar navigation system.
