This project aims on demonstrating accelerating electron beam injected from linac in plasma accelerator driven by CO2 laser
The project will explore a large (e.g. psec or 0.5 mm) length of “bubble” in CO2-laser driven plasma wake-field accelerator. Injecting of an external high quality electron bunch with duration ~ 10 fsec synchronized with the “bubble” would allow us to accelerate high quality electron beams with energy stability and spread reaching towards 1E-4. We rely on CO2-laser power upgrades that are in progress at BNL. We present our considerations for visible diagnostics, plasma source with ramp-up and ramp-down density profiles and the electron bunch compressor to 10 fsec with emittance preservation. We present current status of the project and first experiments planned for 2016.
This project is supported by DoE HEP office grant #215125.
