Construction of a Cosmic-Ray Veto Shield for the Summing Na(Tl) Detector
Dr. Paul DeYoung
Cosmic rays, which are constantly penetrating the SuN detector, produce signals in SuN similar to the . radiation SuN is designed to detect. A cosmic-ray veto detector was built in order to identify these signals and remove the background from SuN data. The veto detector consists of nine scintillator bars with a photomultiplier tube on each end. These bars were mounted horizontally and will be placed above the SuN detector in order to detect cosmic rays before they penetrate SuN. Data will be taken with the SuN and the veto detector simultaneously and the cosmic ray events will be removed offline. The first experiment with SuN and the veto will be in the spring of 2014.
