Description
Brookhaven National Lab’s NSLS-II storage ring currently utilizes two 310kW Klystron Transmitters and one 310kW Solid State Amplifier (SSA) to support its operations. Each Klystron Transmitter is comprised of a 310kW klystron, a 50 kV cathode power supply, several commercially available power supplies along with controls and interlock systems. These Klystron Transmitters have been in operation since 2012 (operational statistics will be presented) and are now facing end of life issues including klystron failures and control system obsolescence/ unavailable spares. An upgrade involving new klystron spares and an updated controls system was investigated- it was determined the complete replacement of one klystron transmitter with a new solid-state amplifier was a more cost effective and reliable approach. This approach also yields a full complement of spare components (klystrons, power modules, etc.) for the remaining Klystron Transmitter.
