Abstract:

We have measured the distribution of ion transverse velocities in the acceleration gap of a magnetically insulated ion diode. The measurement is based on observing the spectral profile of the Dropper broadened spontaneous line- emission from accelerating ions. The velocity distributions of C and Al ions were peaked at zero transverse velocity and symmetric with respect to the directions parallel and antiparallel to the magnetic field lines. The mean transverse velocities for the two ion species corresponded to energies of about 200eV in experiments with a gap potential difference of 260-330kV. The divergence angles observed for both ion species are significantly smaller than previously observed for protons outside the diode. rrh
