摘要
The laser wakefield acceleration (LWFA) experiments has been conducted by the use of 2 TW. 90 fs laser pulses synchronized with an electron beam injected from a 17 MeV RF linac. Preliminary experiments demonstrated the energy gain more than 200 MeV attributed to ionization-induced self-modulation and self-guiding of intense ultrashort laser pulses in plasmas. Measurements of the plasma density oscillation and laser-plasma interactions support the enhanced acceleration. We are also developing an RF photo-injector producing low emittance beams, a capillary plasma wave guide generating long stable wakefields and a energy measurement system with emulsion technique.
