Recent Developments and Plans for Two Bunch Operation with up to 1 {\mu s} Separation at LCLS
Decker, Franz-Josef.
Two electron bunches with a separation of up to 1 {\mu s} at the Linac Coherent Light Source (LCLS) is important for LCLS-II developments. Two lasing bunches with up to 220 ns separation have been demonstrated. Many issues have to be solved to get that separation increased by a factor of 5. The typical design and setup for one single bunch has to be redressed for many devices. RF pulse widths have to be widened, BPM diagnostics can see only one bunch or a vector average, feedbacks have to be dou... Show Full Abstract
Two electron bunches with a separation of up to 1 {\mu s} at the Linac Coherent Light Source (LCLS) is important for LCLS-II developments. Two lasing bunches with up to 220 ns separation have been demonstrated. Many issues have to be solved to get that separation increased by a factor of 5. The typical design and setup for one single bunch has to be redressed for many devices. RF pulse widths have to be widened, BPM diagnostics can see only one bunch or a vector average, feedbacks have to be doubled up, the main Linac RF likely needs to be un-SLEDed, and special considerations have to be done for the Gun and L1X RF.
