Abstract

The klystrons in use at CEBAF are operated at low efficiency and the prices for servicing of existing tubes and for purchasing spare tubes have been increasing. FAR-TECH, Inc. studied a number of options in regards to improving the efficiency of the klystron systems, as well as replacement technologies such as solid state amplifiers. In Phase I, the solid state amplifier option was identified as the best alternative, and is being adopted as the Phase II plan. In Phase II, two complete prototype systems will be developed, tested, and integrated with the CEBAF accelerator system. The system will address the unique requirements of the present klystron installation, including tight space requirements, a high-efficiency design, reliability, and serviceability. Commercial Applications and Other Benefits: FAR-TECH sees many benefits to this new technology to accelerator projects, both at national labs and universities, and in the private sector. Non-accelerator applications also exist, as the amplifier can meet general-purpose needs.
