The high-brightness ultra-short pulsed electron beam source at Peking University

In this paper the characteristics of an ongoing new high-brightness ultra-short pulsed electron beam source in Peking University is reported. The results of the experiment on the DC laser-driven electron gun are shown, together with the preparation of the photo-cathode, which has a much improved performance. Based on these achievements the new electron source will adopt a superconducting accelerating section, thus it is expected to obtain electron beams of 1–2MeV as a first step, and it is expected to reach a higher energy range in the future.
