3kV Ion Source Package

3kV Large Area Ion Source and Controller

RBD's 3kV Large-Area Ion Sputter Package comprises an electron discharge source, power supply, and cable. Designed to operate as low as 100 eV, the 3 kV ion source provides a large 10 mm spot size, uses argon gas, and does not require differential pumping.

The package includes ion source, electronic control unit, sample current meter, cabling, operating manual and a spare filament assembly.

Theory of Operation

The 3 kV Ion Source is an oscillating electron discharge source with electrostatic extraction and focusing lens. Argon gas is leaked directly into the discharge chamber where ions are formed at a selected energy of between 100 and 3000eV. The ions are extracted and focused into a spot of approximately 10mm diameter at the sample surface where the impact of the energetic ions physically removes surface material.
