Abstract : The need for a single element charge transfer device as a spectroscopic detector is discussed. Such a detector promises to offer superior performance compared to current photomultiplier tubes over a wide range of illumination levels. As a detector to address this need, the prototype CID75 manufactured by General Electric Co. is described and characterized. The CID75 is a single element CID sensor with a 1mm by 1mm photoactive area and readout rate adjustable from 0 to 20 kHz. The electro-optical characteristics reported in this study include linearity, read noise, full well capacity, dark count rate, and quantum efficiency. The sensors have good photometric linearity with a full well capacity in excess of 1.2 X 10 to the 8th power electrons. The read noise of the detector can be lowered to 80 electrons when employing the nondestructive readout mode of the CID. The quantum efficiency of the CID75 is reported for the wavelength range of 200-100 nm. Keywords: Charge injection device, charge transfer device, spectroscopic detector.
