Description

A 2.45 GHz microwave proton source has been designed, fabricated, and tested on a laboratory test bench. The source utilizes an electromagnetic structure for electron cyclotron resonance (ECR) plasma generation. After careful assembly and vacuum conditioning, the beam commissioning was carried out. A Faraday cup installed at the beamline end was used to measure the extracted proton current. A stable proton beam of 2 mA was successfully measured, demonstrating reliable source operation. The results confirm the performance of the source under typical laboratory conditions. Further optimization of beam emittance and stability is underway for future linac applications.
