Abstract
A large area SDD detector having linear anodes surrounded by steering electrodes and having an oblong, circular, hexagonal, or rectangular shape. The detectors feature stop rings having a junction on the irradiation side and an ohmic contact on the anode side and/or irradiation side. The irradiation and anode stop ring biasing configuration influences the leakage current flowing to the anode and, hence, the overall efficiency of the active area of the detector. A gettering process is also described for creation of the disclosed SDD detectors. The SDD detector may utilize a segmented configuration having multiple anode segments and kick electrodes for reduction of the detector's surface electric field. In another embodiment, a number of strip-like anodes are linked together to form an interdigitated SDD detector for use with neutron detection. Further described is a wraparound structure for use with Ge detectors to minimize capacitance.
