WebAs examples, bunch length related measurements at Jefferson Lab are presented. At Jefferson Lab, bunch lengths as 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 for low charge bunches. Webresults and shows that the CSR and CTR signal strengths vary similarly with phase. This is graphically shown in the plot of Fig. 8. This would be expected since they both are monitoring the coherent radiation from the same bunch length that results from the compression process.
