Quantum Efficiency Measurement for UV Detector Development
Abstract
UV photon detection is infamously difficult with silicon CCDs, due in part to shallow absorption depths in Si semiconductors, typical surface defects, and absorption by front surface circuitry. Only recently have new developments in coatings and surface passivation (i.e. Delta-doping) helped make CCDs a competitive option for UV astronomy. Our lab at Steward Observatory is currently using a customized UV-Vis monochromator to characterize the efficacy of these technologies. We use a McPherson 207V Monochromator with collimator and deuterium and xenon lamp sources to measure the spectral response of our detectors. With this setup we can measure detector throughput across an effective range of ~150-700 nm in wavelength, with sub-nanometer spectral resolution allowing for precise measurement of a detector's spectral response. Our lab is currently working on testing e2v's 201-20 EMCCD that are both delta-doped and given an anti-reflection (AR) coating by collaborators at JPL. Here we provide information on our test setup and testing process as well as preliminary results for our experiment with these coatings....
