Monoenergetic Electron Beams with Ultralow Normalized Emittance Generated from Laser-gas Interaction *

High quality electron bunches were generated by using 2 TW, 80 fs high contrast laser pulses interacting with helium gas targets. In optimized experimental condition, we got tens of MeV monoenergetic electron beams with small energy spread and the normalized emittance reaches 0.07π mm·mrad. Experimental and simulation results show that proper plasma densities make the injection more stable and ...

Laser-based Profile Monitor for Electron Beams*

High performance TeV energy electron / positron colliders (LC) are the first machines to require online, non-invasive beam size monitors for micron and submicron for beam phase space optimization. Typical beam densities in the LC are well beyond the threshold density for single pulse melting and vaporization of any material, making conventional wire scanners ineffective. Using a finely focused,...
