General description
The RF ion source Model SO-173 long bottle is a long life ion source for general purposes. It is a heavy-duty prolific source of hydrogen and other gaseous ions. The source bottle contains a gas, which is excited by an RF (Radio Frequency) oscillator capacitive coupled to the bottle. The plasma is confined and positioned by an axial magnetic field. The source output is optimized by control of the source gas pressure, magnetic field and oscillator loading. The source bottle is fitted with a replaceable canal, available in different aperture sizes and materials. The RF ion source Model SO-173 is suitable for single ended accelerators with high-pressure insulation gas as well as tandem injectors in combination with a charge exchange canal at atmospheric pressure.

The long bottle RF ion source is available in two configurations:

CX-SO-173-003, which is equipped with a Pyrex source bottle provided with an aluminum cap termination for maximum lifetime at full source output. The magnetic field is produced by a tunable electro magnet for optimization for different charge states and different elements. The ion source is equipped with a 2.10 mm tantalum lined aluminum source canal for operation with heavy ions.

CX-SO-173-004, which has the same configuration as the CX-SO-173-003, but is equipped with a quartz bushing and a different source bottle. Instead of the aluminum cap termination this bottle is provided with a tungsten extraction pin functioning as anode. To protect the extraction pin from electron erosion caused by back streaming electrons, a
quartz baffle is installed at the top of the bottle. The magnetic field is produced by a permanent magnet. The ion source is provided with a 2.10 mm stainless steel lined aluminum canal. This source has a high output and is designed for accelerators with nanosecond pulse equipment.
