Design considerations for a density-channel-guided laser wake-field accelerator. Interim report
A self-modulated laser wake-field accelerator configuration in which the laser pulse is optically guided by a plasma density channel is considered. Preliminary experiments on the generation of a plasma channel by a slow capillary discharge are described. It is shown that homogeneous channels with length L sub channel >> lambda{sub p} can be produced, where lambda{sub p} is the plasma wavelength. Key issues are addressed, including phase detuning between the accelerated electron bunch and the wake field, beam-plasma and laser-plasma instabilities, and the effect of density variations that might occur over the length of the plasma channel. Numerical simulations, using present experimental parameters, show accelerating gradients in excess of 50 GV/m.
