Physics tests of an electron suppressor with variable electric and magnetic fields

This paper reports tests of an electron suppressor, for volume negative ion sources with variable electric and magnetic fields. The experiments have been carried out with a source and accelerator operating d.c. and with an extraction aperture of 16 mm diameter. The results are compared to those obtained with a permanent magnet suppressor and to a theoretical model of the transport of electrons by diffusion across the magnetic field.
