Paper Abstract

We present the Event Pre Processor (EPP) for the Cadmium-Zinc-Telluride-strip detector of the Hard X-ray Imager (HXI) onboard of the MIRAX satellite. The purpose of the EPP is to provide an onboard data reduction and event filtering by applying a non linear energy gain correction for each detector strip. This data reduction is necessary because of the limited telemetry capacity of the MIRAX satellite. We decided to use hardwired data processing electronics based on a Field Programmable Gate Array (FPGA) chip designed in VHDL. This solution allows us to combine high computation power with low power consumption. We discuss the functionality and status of the EPP design developed in T&diaeru;bingen.
