The NEC positive RF ion source has been used primarily to produce H+ and He+ ion beams. However, it has produced modest currents of oxygen, chlorine, and other positive ions from gaseous elements. It is ideal for use in high voltage terminals of electrostatic accelerators.
The NEC positive RF source has two unique features:
The standard design utilizes a permanent magnet. However, NEC also offers a version that utilizes adjustable solenoid magnets. This allows for better control and higher currents.
Running the standard RF ion source in a 3 MV Pelletron accelerator terminal, the source can produce an analyzed H+ beam on target of 120μA.
