Neutron yield from the plasma of a coaxial accelerator

The neutron yield from a plasma produced in a coaxial accelerator in a homogeneous longitudinal magnetic field has been measured. The imposition of even a weak magnetic field (below 1 kOe) greatly reduces the neutron yield (by a factor of 4--5). The reason may be a decrease in the plasma density due to an increase in the cross-sectional area of the plasma.
