Abstract

Electron collection at the anodes of large-area silicon drift detectors was studied with STAR2 prototypes. Results of measurements of anode leakage currents, signal dependence on focusing voltages, anode uniformity, and model simulations are reported. A design of the anode region is presented. The design optimization is discussed.
