Description
EMP pulses emitted during laser plasma interactions have been studied experimentally and the scaling dependence on target parameters is becoming better understood (P Bradford et al, HPLSE, 6, E21, 2018) Using a recently developed cryogenic target system, an ultra thin layer of deuterium can be readily deposited as a pure low Z surface layer. By controlling the thickness of the deuterium layer it can act as a probe of the acceleration sheath dynamics. Studies using the Vulcan ps laser showing the dependence of the EMP and the escaping electrons using a series of B-dot and D-dot probes and ancillary diagnostics will be presented.
