Available in PDF, EPUB and Kindle. Book excerpt: An open iris-loaded waveguide structure is considered for laser acceleration of highly relativistic particle in vacuum. Complete characterization of eigenmodes are given in analytical form for the structure. In particular acceleration performance of the dominant TM mode is evaluated in detail. Transparent scaling laws are derived, and through which significant advantages over other vacuum laser acceleration schemes are demonstrated. 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 [mu]m.
