Study and Characterization of a Gamma Ray Imaging System

Michael Sori


ABSTRACT: The purpose of this thesis was to characterize the CCD camera and the optics system of a gamma ray imaging system. Such an imaging system is desirable for an optimal use of a gamma ray beam in an experiment or application. We studied the theory behind charge-coupled devices and aberration and made measurements for certain characteristics of the system. It was found that the SXVF-M7 camera used takes accurate measurements 30 minutes after being powered on, and that the camera has a readout noise of 14.4 electrons per pixel. It was measured to have a dark current of 30.5 electrons per second per pixel and a noise floor of 420 electrons per pixel. The optics system was found to be able to resolve objects on the order of 100 microns. The optics system was measured to give no significant distortion and a magnification of 10.6% +/- .2% in the x-direction and 10.9% +/- .2% in the y-direction.
