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%. 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, …
