Measurement of angular distribution of beam electrons at GESA facilities

In the paper results of measurements of an angular distribution of intense beam electrons are presented. The measurements were performed at the GESA-1 and GESA-2 facilities. At both facilities multipoint explosive emission cathodes are used as an electron source. The beam is formed and transported with the help of external magnetic field. Measured angular distribution is in a good agreement with calculated one. The influence of the magnitude and distribution of magnetic field, cathode points density, accelerating voltage on the angular distribution was investigated.
