NSLS-II RF Systems: Status and Upgrade Plans
Presented by Mr. James ROSE on 8 May 2012 from 09:30 to 10:00
Session: Session 1
The NSLS-II is a third generation 3 GeV light source designed for 500mA of circulating current and up to 1.2 MW of installed RF power. The RF systems consist of a 200 MeV S-band pulsed LINAC, 90 kW IOT based transmitter powering a 7 cell cavity for the booster and up to four 500 MHz SRF systems and two 1500MHz SRF passive cavities in the storage ring distributed equally in two RF straight sections. Only one of the storage ring RF straights are funded in the project baseline (two 500 MHz and one 1500 MHz systems). The project has taken the conservative approach of two 300 kW klystron transmitters powering CESR 500 MHz SRF cavities for the project baseline, along with a passive SRF 1500 MHz cavity for bunch lengthening. An R&D program is looking at competing technologies for the second two 500 MHz RF systems including combined solid state transistor amplifiers at ≥ 400 kW each and new cavity coupler designs. Status of the LINAC, booster and SR systems will be given as well as an overview of the R&D program will be presented.
