摘要：

The electron loss current from the central plasma of a 10 GHz Caprice ion source is analyzed by using a multigrid electrostatic analyzer. It is found that the plasma potential near the axis is negative in the range - 10 to - 30 V when the rf power varies from 100 to 450 W. It is also shown that cold electrons having a nearly Maxwellian distribution with T(ec) parallel-to approximately 25 eV, and warm electrons nearly Maxwellian with T(ec) parallel-to of a few hundreds of eV, are the two components of the measured electron population.
