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%. songs of berlin berlin jazz orchestra eanWebCSR bunch length monitor Needs beam timing trigger Gated ADC required to read signals from pyroelectric detectors, <8 channels Need to be able to correlate the new GADCs with existing BPMs in the SCP Standardize on GADC type(s).
