Development of Silicon Detectors for the Maryland Electrostatic Energy-Charge Analyzer

Rectangular, 100μ thick surface barrier, and 1 mm thick lithium-drifted-silicon surface barrier detectors have been developed for the University of Maryland Electrostatic Energy-Charge Analyzer on the IMP H and J satellites. Fabrication techniques are discussed which influence detector properties such as injecting contacts, windows, trapping, and n- and p-type surfaces. Aspects of detector reliability, the selection of flight detectors, and some causes of detector failure are considered.
