【Abstract】 The evaluation results of the CCD system in Prism-Spectro Photometer, PSPO, are described. The instrument employs TH7832 CCD as detector, which works at temperatureof - 130℃--11 0℃ . The system has good stability and linearity. Readout noise is about300 electrons and dynamic range 3500. The quantum efficiency of the detector will be calibrated with the optical system in real observational environment. Further improvements on the readout circuit and system gain are discussed.更多还原
