A gallium arsenide CCD X-Ray detector Patten, Scott


A one dimensional buried channel CCD with a 30 /urn thick intrinsic layer was manufactured at TRIUMF for use as a radiation detector. In order to characterize the detector's response to radiation, six discrete X-Ray sources with energies ranging from 8 KeV to 60 keV were impinged on the device. An algorithm was developed to convert events detected by the CCD into spectra characteristic of each X-Ray source. The range of energies detectable and the energy resolution of the detector at different energies were studied.A model was developed and used to explain the shape of each spectrum. The spectrum from an 241Am source was also studied to determine the detector's response to a multi-energetic source.
