SLAC fires up electron gun for LCLS-II X-ray laser upgrade
2019年5月30日 · Crews at the Department of Energy’s SLAC National Accelerator Laboratory have powered up a new electron gun, a key component of the lab’s upgrade of its Linac Coherent Light Source (LCLS) X-ray laser, and last night it fired its first electrons.
Electrons now moving through the superconducting accelerator …
2023年8月7日 · To start LCLS-II’s electron laser beam, an electron gun has to knock electrons free from atoms, hence the name X-ray free-electron laser, or XFEL. Since electrons are lighter and easier to knock out of atoms than other particles, scientists choose them as their go-to particle for X-ray laser experiments.

The design of high-brightness ERL-FEL injector based on VHF electron gun
This electron gun features an accelerating gap of 40 mm, with an estimated total RF input power of approximately 70 kW required to accelerate the beam to 720 keV. The normalized emittance is a critical parameter for FEL lasing, and to mitigate the growth in emittance at the exit of the gun, a solenoid is employed.
