Paper Abstract

THe resolution and sensitivity of the special sensor UV limb imager (SSULI) spectrograph depend strongly on the quality of the detector. As a result, the Naval Research Laboratory (NRL) has given high priority to the refurbishment of a damaged detector and tow spares to evaluate possible improvements to the overall capabilities of the SSULI sensor. The goal of the detector refurbishment is to improve the detector imaging quality, counting efficiency, resolution, background uniformity, long term vacuum storage, and serviceability. Estimated improvement sin the sensor performance will be used to determine the feasibility of refurbishing all the remaining detectors and spectrographs. The NRL is currently refurbishing a SSULI detector. The completion of the detector refurbishment includes a detailed analysis of the detector performance. This paper describes the performance of the refurbished SSULI detector and a comparison tot he original detectors. Included is a detailed description of the testing methods and result as well as the impact to the performance of the SSULI spectrograph. The test that will be reported are counting efficiency, image uniformity and quality, gain variability, background uniformity, and anode alignment.
