Title :
Laser acceleration in vacuum with an open iris-loaded waveguide
Author_Institution :
Lawrence Berkeley Lab., CA, USA
Abstract :
An open iris-loaded waveguide structure is considered for laser acceleration of highly relativistic particles in vacuum. Complete characterization of all eigenmodes are given in analytical form for the structure. In particular the dominant radially polarized TM mode is evaluated in detail for laser acceleration. The entire parameter space is searched and it is found that below the laser damage threshold of the structure an acceleration gradient around 1 GV/m can be obtained over a phase slippage length of 10s of cm with TWs laser in the wavelength range from 1 to 10 μm
