Abstract:

We are developing an inexpensive compact accelerator system primarily intended for pulsed radiography. Design characteristics are an 8 MeV endpoint energy, 2 kA beam current, a cell gradient of approximately 3 MVm for an overall accelerator length is 2-3 m, and 1Volt capital costs. Such designs have been made possible with the development of high specific energy dielectrics 10Jcm3, specialized transmission line designs and multi-gap laser triggered low jitter 1 ns gas switches. In this geometry, the pulse forming lines, switches, and insulatorbeam pipe are fully integrated within each cell to form a compact, stand-alone, stackable unit. We detail our research and modeling to date, recent high voltage test results, and the integration concept of the cells into a radiographic system.
