Funding: This project has been supported by the Swiss Commission on Technology and Innovation under KTI grant number 13192. PFFLM-IW. When considering complex heavy ion accelerator systems for medical use, scientists and engineers rapidly recognize the importance of reliability and simple maintenance for components such as RF amplifiers. While amplifiers used in particle accelerators have typically been designed around vacuum tube technology, developments in solid state RF amplifiers have led to new systems offering the potential for extremely high reliability and in-built system redundancy. These characteristics are especially important for expensive medical systems that require 24/7 operation to maximize efficiency. In conjunction with the Paul Scherrer Institute, we have developed a novel 500MHz solid state RF amplifier for use in medical accelerators. This modular system has been initially designed and built to deliver 65kW output RF power with exceptional power efficiency and extremely good reliability. The modular design allows it to be adapted for power levels up to 300kW at frequencies between 200MHz - 1.3GHz. Our presentation reviews the 65kW system, reporting results from performance and resilience testing, and developments for future use in heavy ion accelerators and other high power RF applications. |
