Abstract: The stability of brightness of the O- beam generated from the douplasmatron ion source is influenced by the gas pressure, the magnetic field strength and the arc current. An ion optical system for measuring the brightness of a duoplasmatron of the SRHIMP II was presented. The brightness of the O- beams as a function of the gas pressure, the magnetic field strength and the arc current was experimentally studied. The results show that longtime, stable operation of the ion source can be realized at the pressure range from 110 mTorr to 170 mTorr and an arc current above 50 mA. The maximum brightness measurements give 52.4 A/(cm2·sr) for O- with 0.25 T magnetic field strength, a low pressure of 140mTorr ere and an arc current of 200 mA. Controlling these parameters reasonably can increase the brightness of O-, improve the lateral resolution and the sensitivity of the secondary ion mass spectrometry.

Key words: technology of instrument and meter, secondary ion mass spectrometry, duoplasmatron ion source, ion optics, ionbeam brightness
