A unique class of physics experiments requires the detection of low energy depositions in large volume radiation detectors. The high purity germanium (HPGe) detector remains the leader in energy resolution achievable from kg-scale detectors. This talk will explore the fundamental sources of electronic noise which limit the low energy threshold in HPGe detectors. Improvements will be demonstrated which can enable the next generation of physics experiments.
Paul Barton received his Ph.D. in Nuclear Engineering from the University of Michigan, where he worked on the development of silicon photomultiplier technologies. He is now with the Applied Nuclear Physics (ANP) program in the Nuclear Science Division at the Lawrence Berkeley National Laboratory (LBNL). The ANP program develops advanced detectors and algorithms for physics, medicine, nuclear science and security. Paul is a co-author of the upcoming 5th edition of Glenn Knoll's, Radiation Detection and Measurement.
