Tomco has supplied a wide range of RF amplifiers for accelerator and plasma applications

  • Rugged CW and pulsed amplifiers
  • Frequencies from 1MHz to 1.3GHz
  • Narrowband and broadband systems
  • Power levels up to several hundred kilowatts

We offer cost effective, tailored solutions and work closely with end users to ensure they get the optimum solution for their budget. 

Our accelerator amplifiers are in use in many facilities driving superconducting cavities and RFQs, driving klystrons and tetrodes, driving ion sources, cavity conditioning, pulsing magnets at high speed in beam kickers and beam choppers, and other accelerator applications.

The specifications listed below are a general overview only of our capability.  Please email (sales@tomcorf.com) to liaise directly with a design engineer or to submit your specifications.

Amplifier Modules

Our amplifier modules are popular choices for OEMs and do-it-yourself spectrometer builders. They are "brick" modules meaning power amplifier stage only with no power supply or mismatch protection. They do include over temperature protection and can be supplied with suitable heatsink and fan assembly.

They offer a versatile, cost-effective solution for the RF amplifier stage of benchtop magnetic resonance systems.
