    SPring-8 is a 3rd generation synchrotron facility. The electron beam energy and current are 8 GeV and 100 mA. There are four RF stations to generate 16 MV total accelerating voltage at a frequency of 508.58 MHz. Each station has eight single-cell cavities driven by one 1MW-CW-klystron. About 27 years have passed since the start of the user operation was in 1997, an upgrade project,...

    A programmable signal processor-based credited safety control that calculates pulsed beam power based on beam kinetic energy and charge was designed as part of the Proton Power Upgrade (PPU) project at the Spallation Neutron Source (SNS). The system must reliably shut off the beam if the average power exceeds 2.145 MW averaging over 60 seconds. This paper discusses the calibration of the...

    The Spallation Neutron Source (SNS) is implementing camera-based systems to enhance the reliability of high-power RF vacuum windows in its Drift Tube Linac (DTL) and Coupled Cavity Linac (CCL) sections. In the DTL, a high-speed camera will detect electron glow discharges sometimes associated with multipacting, a critical issue leading to window damage. This effort is part of a broader project...

    Talk

    In the spring of 2021 NSLS-II commissioned the project’s first SSA high power transmitter (310 kW CW) to complement the two existing 310 kW klystron-based transmitters which had been in use since 2012. This presentation will present the technical performance of the system as well as detail the hardware and software failures that occurred and the resulting downtime accumulated over the past...
