Academic Achievement
DENG Xiujie has been concentrating on the physics research of an advanced accelerator concept called "steady-state microbunching (SSMB)" in the past decade, with the following achievements: 1) Together with collaborators in Tsinghua, HZB and PTB, he has experimentally demonstrated the SSMB mechanism for the first time in a real machine, with results published in Nature; 2) He has conducted a systematic study on the new physics of SSMB and answered the question of how to achieve SSMB from a beam dynamics perspective. He has published the world's first monograph on SSMB, and more than ten papers in journals such as PRL and PRAB; 3) He has proposed a solution for a kilowatt-level extreme ultraviolet light source based on SSMB.
