  A high-average-current VHF electron gun operating in the CW mode is under construction at Shanghai Advanced Research Institute, which is the key component of a kW-power-order free electron laser facility. The average current and the frequency of this electron gun is 1-10 mA and 217 MHz, respectively. To validate the performance of this instrument, a test platform has been designed. The R&D of its vacuum and diagnostics are presented in this work.

In this contribution, we review the low-energy electron injectors for existing X-ray Free-Electron Laser (XFEL) facilities focusing on the buncher and booster sections. The technology choices are parallel to the increasing demand for stricter six-dimensional phase space quality. The current capability for beam parameters and future requirements are laid out alongside a discussion on challenges and technological bottlenecks. In light of this review, preliminary results for a high capability injector providing high repetition rate, and continuous wave emission is presented as an option for the UK XFEL.
