Title: High Efficiency RF Power Sources for Accelerator Applications

Abstract

The objective of this research is to develop RF power amplifiers in the 10-kW range that can achieve a power efficiency higher than 80% at 952.5 MHz and below. The main target application is power sources for linear accelerators. The ultimate purpose of this research is to save money by reducing energy consumption over the operating lifetime of the amplifier, which is usually considered to be 20 years. That is, the cost of purchase, installation and maintenance plus the cost of electricity over 20 years should be lower compared to currently available amplifier products on the market. This report describes the design and simulation of a 12.5 kW power amplifier for 952.5 MHz continuous-wave operation that is capable of achieving an ac to RF power efficiency of 80.4 %, designed for use in linear particle accelerators, but that can also be employed in many other applications. To the best of our knowledge, there is no precedent of this level of performance to have been ever demonstrated. The report also includes measurements of the fabricated main power amplifier module to prove that this high efficiency can actually be achieved in practice. The cost savings by using this high efficiency amplifier aremore » very significant over its lifetime. According to our analysis, even at an electricity price as low as 6 cents per kW/hr, this amplifier can save 13.9 % in purchasing and operating costs compared to a typical vacuum-based amplifier and 59.2 % compared to existing solid-state solutions. In European and Japanese markets, where the price of electricity can be as high as 20 cents per kW/hr, the savings can be 27.2 % and 94.6 %, respectively.« less
