Description

We present the first time resolved OTR angular distribution measurements of an intense pulsed electron beam (1.7 kA, 60 ns). These initial experiments on the first axis of the Dual Axis Radiographic Hydro-Testing (DARHT) facility and subsequent analysis, demonstrate the possibility to extract, from the data, the energy and the divergence angle of a 3.8 and 20 MeV electrons.
