Abstract :
In recent experiments of Laser Wakefield Acceleration (LWFA), ultra-short (sub 50fs) monoenergetic (energy spread of a few percent to twenty percent) electron bunches of high charge (10s of pC to a few hundreds of pC) with energy range from 100MeV to 1GeV have been observed. In most of these experiments the laser drivers undergo significant longitudinal and transverse evolution during the acceleration process. How to extend the results from these experiments towards a more stable regime conducive to making an accelerator is of fundamental importance. In a recent work, a phenomenological theoretical framework of the blowout regime was developed to address this quest. In this paper, a design table based on this theoretical framework will be provided to illustrate possible parameters for reaching GeV to TeV energies.
