WebThe CSR is detected by a pyroelectric detector with a simple organic lens optical system. We examined the CSR monitor at BC2, and measured the bunch lengths using it combined with that of an rf deflector cavity. The results indicated that the monitor enables us to measure the sub-picosecond bunch length with a precision of less than 10%. Webthe BC. The requirement to the bunch length stabilization is less than 10% [2]. We have developed a bunch length monitor utilizing coherent synchrotron radiation (CSR) …

The bunch length monitor systems are used for bunch length feedback control to obtain the stable lasing by changing the rf parameter of acceleration cavities before the BCs. A preliminary system for the above mentioned system was tested at the ... WebSep 20, 2007 · The Particle Beam Physics Lab (PBPL) at UCLA is developing a single-shot relative bunch length monitor system for the Linac Coherent Light Source (LCLS) X-ray Free Electron Laser at SLAC.
WebJul 6, 2012 · Applications include pump-probe x-ray science and the production of THz radiation in the CSR regime. Measurements of the bunch length are difficult, however, because the light intensity is low and streak cameras typically provide resolution of only a few ps. Tests are now underway to resolve the short bunch length using cross …
