2017 International Germanium Detector Technology Workshop

Dec 4, 2017, 8:30 AM → Dec 5, 2017, 5:55 PM US/Pacific

Auditorium (Building 50)

There have been a proliferation of cutting-edge physics experiments and radiation-detection applications that deploy advanced high-purity germanium detectors. Future experiments — some of which are already in the design stage — will push the technological frontier further. As researchers from different fields are formulating their innovative ideas, this is an opportune moment to share their expertise and experience. The main goal of this workshop is to bring together researchers who are interested in germanium detector technology
