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%.
