Ice Exercises 2016 Logistics and Engineering Support Every few years, APL-UW engineers travel to the Arctic to provide logistics and engineering support to the U.S. Navy submarine force and the Arctic Submarine Laboratory. They assemble a reliable shelter on the sea ice and assist with the experimental testing of scientific and military equipment in the Arctic environment. |

Silicon drift detectors have been successfully employed in both soft and hard X-ray spectroscopy. The response function to incident radiation at soft X-ray levels has been well studied and modeled, but less research has been published on response functions for these detectors to hard X-ray input spectra above 20 keV. When used with hard X-ray sources a significant low energy, non-peak response exists which can adversely affect detection limits for lighter elements in, for example, X-ray fluorescence spectroscopy. We present a numerical model that explains the non-peak response function of silicon drift detectors to hard X-rays based on incoherent Compton scattering within the detector volume. Experimental results are presented and numerically compared to model results. |
