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.

Measuring the Bunch Length of the Booster Neutrino …
WebIt should be noted that bunch length is often de ned as a multiple of ˙ depending on what percentage of signal should be included. In this document ˙will be reported as the bunch length. Assuming a normal longitudinal distri-bution, 4˙would then account for 95% of the bunch. Another issue of concern is the baseline o set of the signal ... WebFeb 22, 2024 · We report picosecond bunch length measurements using an interferometric method for a 3 MeV electron beam having bunch charge ranging from 1 to 14 pC. The method senses the single-cycle sub-terahertz (THz) pulse emitted by each electron … WebDec 11, 2024 · When measuring the bunch length with coherent radiation, it is important to obtain the radiation spectrum accurately over the necessary wavelength range. Other methods of measuring the ultra-short bunch length offer excellent accuracy, e.g., 60 fs using EO sampling or 10–20 fs using the transverse deflecting structure [9,10,11]. … emergency room clip art
