Description
The Advanced Light Source (ALS) is a 3rd generation light source operating in her 17th year and is in the midst of a vigorous series of upgrades including Top-Off, Magnet PS’s, SRRF, Insertion Devices, Control System & Diagnostics that will keep ALS near the forefront in its specific synchrotron radiation regime. The Storage Ring RF is being upgraded over the next three years to meet a modest increase in electron beam power and to modernize several sub-systems to increase their maintainability and reliability. Currently the SRRF consists of a single 500 MHz 330kW klystron that powers two normal conducting single-cell RF cavities, an analog based LLRF system, a HVDC Power Supply with Ignitron based crowbar system and a functional yet inflexible diagnostic and control system. The upgrade plan is to replace the single klystron with two that will enable independent control of each cavity, to install a new FPGA based LLRF system, to modify the HVDC PS, to replace the crowbar system with an IGBT based HV dis-connect switch, to replace the controls with PLCs and to upgrade the diagnostic systems. Details of the SRRF Upgrade will be presented in this talk.
