文摘

A microwave ion source is used as an ion source for the 100-MeV proton accelerator at the Korea Multi-purpose Accelerator Complex (KOMAC). The specifications of the ion source are a 50-keV energy and a 20-mA peak current. The plasma is operated in the CW mode by using a magnetron, and the pulse beam is extracted using a semiconductor switch located in the extraction power supply. The beam characteristics were measured based on the pulse voltage and current. A test stand was also installed to study the beam characteristics of the ion source off-line. In this paper, the pulse beam characteristics of the ion source are presented, and the installation of the test stand is reported.
