Taiwan Photon Source (TPS) is a 3 GeV third-generation light source operating at a storage current of 500 mA. It currently operates with two RF stations, each capable of providing 300 kW of RF power. In the original design, each RF station employed a 500 MHz klystron-type RF transmitter. In August 2023, we switched one of the klystron-type RF transmitters to a 500 MHz home-made solid-state...
A new radiofrequency (rf) driver amplifier is being designed to replace 3 kW rf amplifiers that are part of the 197 MHz rf system in the Relativistic Heavy Ion Collider (RHIC) located at Brookhaven National Laboratory. A prototype was built using a gallium nitride device able to operate up to 100 V on the drain side. First measurements indicate that a single unit can generate power in excess...
Los Alamos Neutron Science Center uses a coupled-cavity linac (CCL) to accelerate H- beam from 100 to 800 MeV. This was the first CCL put into operation (1972) and is powered by forty-four 1.25 MW 805 MHz klystrons developed in the same era. Replacement klystrons have had mortality rates higher than tubes made over 25 years ago. This has caused us to embark on a new initiative to develop a...
The Advanced Photon Source (APS) user facility began operation by delivering first x-ray on March 26, 1995. Over the many years, the RF Group maintains and improves four different types of rf powers systems. One system consists of a high-power pulsed klystron within the Linear Accelerator (LINAC), two different types of rf power systems within the Positron Accumulator Ring (PAR), and a Booster...
