WebJan 11, 2024 · The coherent synchrotron radiation (CSR) at the chicane bunch compressor may introduce a beam-tilt in the bend-plane ... We used the bunch length measured with the deflector-based bunch length monitor (DF1 and SCM-H11) to calculate the mean-energy-offset of Fig. 6(a). The tilt angle of the e-bunch shows the expected tendency, … 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%.

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 … free hiver
Beam tuning and bunch length measurement in the bunch compression ...
Web¥Only relative bunch length is needed- not absolute bunch length ¥Need two bunch length monitors- one at each bunch compressor[1] ¥Single-shot ¥Non-invasive ¥Maintenance free for several days ¥Possibility to run at 120 Hz ¥Single-shot measurement resolution: 1-2 % of nominal bunch length ¥Long term signal drift: <2% over ~24 hours … WebDec 14, 2024 · As examples, bunch length related measurements at Jefferson lab are presented. At Jefferson Lab, bunch lengths s short as 84 fs have been systematically measured using a zero-phasing technique. A highly sensitive Coherent Synchrotron Radiation (CSR) detector has been developed to noninvasively monitor bunch length … Web‘sub-picosecond bunch length monitor’ to mean an accelerator diagnostic that attempts to provide ... (CSR), etc. Remember also that the field radiated or probed is related to the Coulomb field near the electron bunch. Therefore, the time response dt and spectrum of the detected field is dependent on the spatial deviation r from the bunch ... blueberry entity
