Abstract

The feasibility of creating additional radiographic sources using some of the loss current in AWE´s next generation flash X-ray machines to is being investigated. Particle in cell simulations of the acceleration region of two paraxial diodes are modelled in the code LSP. These simulations represent trial of this system on the pulsed power accelerator EROS in what is expected to be an overly challenging close, 80 mm axis to axis separation, of two beams. The simulations are used to predict that the electron beams could transit the 50 mm gap with negligible deviation. The design of the experiments to test this system are then presented. Comparison is made to previous work with the beams at significantly greater separation.
