Abstract :
We present an initial design of a proof-of-principle experiment on the Laser Wakefield Accelerator (LWFA). The experiment will utilize the NRL Table-Top Terawatt (T3) laser system as the driver for the wakefield in a pulsed-valve gas jet plasma, and a ~1 MeV Febetron as the electron beam injector. The LWFA will be operated in the self-modulated regime [1] where enhanced acceleration gradients and extended interaction distances can be achieved. Numerical simulations demonstrate that with the present parameters of the T3 laser, peak accelerating gradients can reach >300 GeV/m and single stage energy gain of >100 MeV can be attained
