Investigations on rf breakdown phenomenon in high gradient accelerating structures

Jiahang Shao received his Bachelor’s degree in Engineering from the Department of Electronic Engineering at Tsinghua University, China in 2011. He obtained his Ph.D. in Engineering from the Department of Engineering Physics at the same university in July 2016, where his major research project in Prof. Huaibi Chen’s group was the experimental study of rf breakdown and field emission in high gradient accelerating structures. Currently, he is a postdoctoral appointee working with Prof. Wei Gai at Argonne National Laboratory, USA, continuing his study on field emission and conducting research on wakefield generation by intense electron beam.
