摘要:
Proton yields in magnetic multipole sources can be increased by the creation of a magnetic ‘‘filter’’ within the discharge volume, although this may introduce nonuniformity in the plasma. We have investigated the properties of a filter which can satisfy the requirements of plasma uniformity and discharge electrical efficiency and creates a proton yield of 87% when a 60‐A beam is extracted at 80 keV. A model describing the behavior of the filter is also described.
