Abstract :
In the pressure range (1-5)×10- torr (H2) the propagation of the beam breaks off halfway the current pulse. This disruption disappears once the pressure and/or the type of gas is chosen such that sufficient current neutralization takes place from the beginning of the pulse. In the same pressure range (H2) there is a coherent shift of the beam energy distribution of roughly 100 keV. This can be explained in terms of space charge neutralization of the virtual cathode potential well. At high pressures (1.4 torr) the beam velocity angle scattering is much larger than can be explained by a theoretical estimate.
