Laser Induced Bunch Lengthening on the ACO Storage Ring FEL,
Abstract
Laser induced bunch lengthening has been measured on the ACO storage ring FEL. The experimental data at low current generally confirms the existing theoretical models, while the high current data is dominated by anomalous effects. As part of the LURE/Stanford Free Electron Laser Project at Orsay, France, we have developed a sensitive method to measure the laser induced change in the electron bunch length. This method is capable of measuring the absolute bunch with a precision of 1%, and fractional changes in electron bunch length as small as 1 part in 100,000. Using this system, we have measured the steady state and time dependent laser induced bunch lengthening as a function of electron current, external laser intensity, RF cavity voltage, the undulator magnetic field, and the detection frequency.
