Radio frequency Focused Interdigital (RFI) Linac
Linac Systems' patented RFI linac is an ultra-efficient RF accelerating structure for ions. The RFI design improves on the standard Alvarez-style Drift Tube Linac by incorporating strong quadrupole focusing inside each drift tube via RF "fingers", rather than permanent magnets. This allows for a much smaller accelerator cavity and greatly increased efficiency compared to competing linac designs.
The RFI was designed from the ground up to handle high duty factors, all the way up to 100% (CW) and relatively high currents (up to 30 mA). These capabilities, along with the possibility of neutron production when paired with Linac Systems' Neutron-producing Target, make the RFI well suited to a large number of applications.
