Abstract：
A permanent magnet microwave ion source with adjustable magnetic field is developed at China Institute of Atomic Energy. The magnetic field in the region of ionization chamber is generated by permanent magnets. Outside the magnet, an iron yoke is installed to adjust the magnetic field, and the yoke can be adjusted easily by hands. With adjustable magnetic field, the ion source can be tuned into the optimized operational condition. From an aperture of 3mm in diameter, 17mA hydrogen beam has been extracted.
