Report on the Tin-II Thermal Neutron Detector
Thermal neutrons have recently become a concern in the semiconductor community where it has been reported that approximately 20% of the single-event upsets are due to thermal neutrons in some devices. The goal of this project is to measure the intensity of thermal neutrons in the High- Performance Computing (HPC) area. This is part of a larger effort to characterize the radiation environment in the HPC area which includes high-energy neutrons as well as thermal neutrons. To accomplish this goal, we designed and fabricated a neutron detector that is sensitive to thermal neutrons called Tin-II. The Tin-II detector consists of two identical 3He ionization chambers with one detector bare and one detector shielded with cadmium. Because the cadmium shielding effectively blocks the thermal neutrons, the difference in count rates between these two detectors reflect the number of thermal neutrons detected. This report summarizes the status of our efforts to develop this detector.
