Event description: 

Synchrotron-based or Free-Electron-Laser-based light sources have proven to be an essential tool in many areas of research, including physics, materials science, chemistry, biophysics and biochemistry, medicine, and national security. Novel electron beam sources with high beam brightness are important for the achievements of these fields. The electron source, which is currently under development, is using two-frequency superposition in a half cell to increase acceleration gradient and improve output beam quality without increasing the RF breakdown probability. The emittance will benefit from this by the reduction of space charge effect. The recent status of bimodal electron gun R&D is presented, including the designs of a novel two-frequency directional coupler, rectangular-to-coaxial mode launchers and beam dynamic simulation.

Lunch will be served beginning at 11:45 a.m. outside WLC-245. RSVP required for the lunch.
