Positive RF Ion Source

The NEC positive RF ion source is used on high voltage decks and single ended Pelletron Accelerators, producing over 100 μA of H and He.

Applications

The NEC positive RF ion source is ideal for use in high voltage terminals of electrostatic accelerators. It has been used primarily to produce H⁺ and He⁺ ion beams. It has also produced modest currents of:

• Oxygen
• Chlorine
• Other positive ions from gaseous elements

 

Positive RF Ion Source Design

The NEC positive RF ion source has two unique features:

• Clamping structure: allows complete disassembly of the RF bottle from the flange for cleaning without return to the factory.
• RF sealed enclosure: surrounds the oscillator and RF bottle to protect sensitive electronics in the area from RF interference.

 

Options

• Standard: uses a permanent magnet.
• Higher control and currents: uses adjustable solenoid magnets.

 

Source Performance

Running the standard positive RF ion source in a 3 MV Pelletron accelerator terminal, the source can produce an analyzed H⁺ beam on target of 120 μA.
