NSLS-II Friday Lunchtime Seminar

"Operation at 500mA average current on the horizon"

Presented by Alexei Blednykh, NSLS-II

Friday, December 6, 2019, 12:00 pm — NSLS-II Bldg. 743 Room 156

500mA average current achieved in NSLS-II. Limitations on the total average current will be discussed in details. Localized heating of the vacuum components was the major issue. Since the heating issues were resolved we were able to demonstrate 500mA during the beam study time. However, for the regular operation @500mA we need more power from the RF system to compensate the synchrotron radiation losses produced by the bending magnets, present and future insertion devices. To mitigate the heating issue and increase the beam stability, bunch lengthening will be beneficial for NSLS-II.
