Femtosecond Electron and X-ray Beam Temporal Diagnostics Using an X-band Transverse Deflector at LCLS | |
|
||
|
X-ray free-electron lasers provide ultrashort x-ray pulses for multidisciplinary users. Temporal characterization of these ultrashort pulses with a femtosecond precision remains a challenging topic. At the Linac Coherent Light Source (LCLS), an X-band radio-frequency transverse deflector proposed in 2011 [*] has just been installed and commissioning of the RF system has started. By measuring the electron beam longitudinal phase space between lasing and non-lasing conditions, both the e-beam and x-ray temporal profiles can be reconstructed. We report the latest progress of the commissioning of the deflector and the measurements on the e-beam and x-ray pulse length with this deflector at LCLS. The resolution, stability and operational performance will also be discussed.
