Recently the UCLA BNL helical IFEL experiment at the Accelerator Test Facility (ATF) showed for the first time capture and high gradient acceleration of monoenergetic electron beams from a helical inverse free electron laser. Using a modest intensity ~1013 W/cm2 laser--several orders of magnitude less than those used in laser wake-field accelerators--and a strongly tapered 0.5 m long helical undulator, we demonstrated energy doubling of a 52 MeV electron beam with >100 MV/m average accelerating gradient and excellent output beam quality. In order to improve the fraction of electrons captured, a prebuncher module is being prepared for testing next month. Simulations show that 70 to 90% of the beam should be accelerated to a final energy of 97 MeV with 2% energy spread. The high efficiency acceleration will enable the first IFEL driven inverse Compton scattering experiment. [ABSTRACT FROM AUTHOR] |
