Description
The construction of a platform for terahertz (THz) radiation research at Peking University has been completed recently. The platform consists of a DC-SRF-II photocathode gun, an superconducting radio-frequency (SRF) linac equipped with two 9-cell TESLA-type cavities, a magnetic chicane for electron bunch compression, and a 40-period undulator with taper control. By integrating with an additional THz parametric source synchronized to the photocathode drive laser, a high repetition rate THz FEL amplifier is going to be demonstrated. Furthermore, benefiting from a powerful photocathode drive laser, superradiant radiation can be studied by flexibly manipulating the temporal profiles of the electron bunches. In this work, we present our research plan and latest progress.
