Project Description

The GRETINA gamma-ray tracking array is an array of gamma-ray detectors that is being used by the nuclear structure community physicists to analyze properties of atomic nuclei. The problem is that when we compare measurements to simulations we see that the simulation is more efficient than the real array. This led us to investigate the size and shape of inactive volumes in the detectors by comparing our simulations with measurements made at Lawrence Berkeley National Laboratory with a pencil beam of gamma rays in order to improve our model of the detectors. Upon investigating these different avenues, the aim is to improve the simulations so that they match the real data and discover more about GRETINA as a whole.
