Abstract

The Large Area Detector (LAD) is an instrument concept for the eXTP and STROBE-X space missions (although for the latter with a different name, HEMA). Based on linear Silicon Drift Detectors (SDD), it performs spectraltiming studies in the 2–30 keV energy range. Due to the harsh particle environment of low Earth orbit, it will be subject to radiation damage in the form of both displacement damage and Total Ionizing Dose (TID). To evaluate the response of the LAD sensor technology to TID, we exposed a prototype of a LAD detector to a⁶⁰Co source for a total of 85 kRad. This allowed us to evaluate the contribution of TID to the end-of-life performance of the instrument.
