M.P. belt deterioration. Accelerator structure. Belt capability
M. Letournel1

An explanation to the M.P. belt deterioration is proposed. It takes into account the strain of discharge to which the belt is submitted following the combination, first of a too high belt charge density in addition to the machine voltage contribution, second the geometrical configuration of the gradient rods which induces an inhomogeneous field and allows the belt to reach too high voltages not compatible with the particular Paschen curve. This explanation leads to define the concept of belt charge capability. The field configuration critical for a certain charge density also exists in other places. Different simple solutions are proposed to cure this problem and allow the M.P. belt to operate under normal electrical conditions.
