Zhong He will be presenting as part of the nuclear engineering seminar series.
Wed, January 30, 2013, 10:15 am - Wed, January 30, 2013, 11:15 am
Seminar Topic: This presentation introduces the technology of 3-dimensional-position-sensitive wide band-gap semiconductor gamma-ray spectrometers. These detectors provide energy depositions and positions in 3-dimensions of individual gamma-ray interactions. This capability of 3-D position sensing and gamma-ray spectroscopy enables real-time gamma-ray imaging based on Compton scattering kinematics at higher energies, and coded aperture at lower energies. The progress made during the past decade and possible applications in international nuclear non-proliferation, homeland security, medical imaging, nuclear power, fundamental physics and planetary sciences will be discussed.
Bio: Zhong He received his B.S. in Physics from Tsinghua University, and M.S. degree at High Energy Physics Institute in Beijing of China. He received his Ph.D. from Southampton University in U.K. in 1993. He has about 80 peer-reviewed publications on scintillation, high-pressure noble gas and semiconductor radiation detectors. He is a professor at University of Michigan, currently focuses on the development of 3-dimensional position-sensitive wide band-gap semiconductor gamma-ray imaging spectrometer systems, and associated application specific integrated circuitries (ASICs). The application areas include national security, nuclear non-proliferation, homeland security, medical imaging, nuclear physics, nuclear power safety and planetary sciences. He has graduated 15 Ph.Ds.
