Dynamical measurements of plasmas generated by relativistic electrons colliding with metal targets

Summary form only given. We present data from a series of diagnostics operating on the ITS linear induction accelerator at Los Alamos National Laboratory. Using interferometry, both at optical and microwave frequencies, we are able to characterize the temporal evolution of the plasma parameters when material is ejected from various targets. Concurrent streak camera measurements of X-ray spot size and Faraday cup measurements of ions are also presented, and the interaction of plasma with the electron beam is discussed. Computer modeling of the interaction between targets and the electron beam is presented and discussed in light of the experimental results.
