The progress of a 2.45 GHz compact microwave ion source with permanent magnet was introduced in this paper. The source outline dimension is Φ100mm×100mm

and its weight is less than 5 kg. It can operate in both pulse and CW mode. At 500 W microwave power

45 kV extraction voltage and 5 mm of diameter of emittance hole on the plasma electrode

100 mA peak current of hydrogen ion beam was extracted in pulse mode

corresponding to a beam density of 500 mA/cm2; at the same conditions 60 mA hydrogen ion current was extracted and beam density was 300 mA/cm2 in CW mode. The proton ratios were about 80% and emittances Erms were less than 0.17πmm·mrad in both modes.
