Abstract

With recent advances in nanotechnology, traditionally bulky systems such as particle accelerators can be scaled down to portable sizes. Here we present a prototype micro accelerator platform which is a laser powered optical structure made of dielectric materials. As the drive laser impinges, the electric field can build up in the resonant gap between the dielectric slabs to as high as 1GV/m and electrons travelling through the gap are accelerated. Fabrication of the device involves advanced lithography, various thin film depositions, as well as fine surface finishing. In this report, we first present simulation results on the resonance and acceleration of the optical structure. Next we discuss the detailed fabrication techniques, and a prototype device will be presented. Finally, the acceleration test setup will be introduced, and some preliminary beam test results will be presented. This micro-sized structure can be used for electron acceleration and to produce X-ray radiation, in a compact device
