A Compact Radio-Frequency Power Supply for Ion and Particle Guides and Traps

In this paper, we present a novel compact rf or ac power generator that uses a resonant driving scheme without the necessity for any matching device. The developed unit also doesn't need any expensive high voltage power supply for generating output voltages in the range of some hundred volts typically required for the function of trapping devices. The high efficiency of the generator allows operation at output powers of around 50 W without any performance losses. The frequency range of the device is determined by the output transformer. It can be easily varied from the megahertz range down to some kilohertz just by replacing the output transformer and several capacitors in the control part of the generator. Thus, our device can be used for supplying traps operating with ions as well as with charged nanoor microparticles. PACS numbers: 84.30.Ng, 82.80.Ms, 29.30.Aj, 07.75.+h, 07.81.+a
