WebDec 11, 2024 · In particular, the bunch compression scheme utilizing the arc section is an important test item in the cERL. In order to tune the beam for bunch compression, a bunch length diagnostics is necessary. Many types of bunch length monitors have been studied in various accelerator laboratories. The most direct and reliable one is the RF deflector … Web200 fs length drive laser: the resulting bunch length is determined by space-charge effects. We present meas-urements made with an S-band transverse deflecting cavi-ty to characterise the bunch length as a function of charge, and as a function of the gun operating phase.
