A compact 2.45 GHz ECR ion source has been developed at National Institute of Radiological Sciences (NIRS). The source was designed to provide doubly charged carbon ions, aiming at easy maintenance of the source. A set of permanent magnets was adopted to realize a minimum B structure. In pulse operation with a duty factor of 5%, the beam performance was measured with He, CO2, CH4, and N2 gases. With CO2 gas, analyzed beam currents are 160 and 15 eμA for C+ and C2+, respectively. Through the measurement of the microwave amplitude in the plasma chamber, it was found that the microwave power was not transmitted into the plasma chamber efficiently. © 1996 American Institute of Physics.
