Pre-Compression of Bunch Length
After extraction, the damping ring (DR) bunch length is eom@essed in the RTL (Ring-To-Linac) transport line to achieve the desired linac bunch length. For this, an energy spread is induced proportional to the DR bunch length, producing large, aperture filling, horizontal beam sizes in the dispersive regions of the RTL. There, nonlinear magnetic fields and wakefields cause higher order dispersio...
متن کاملSingle-shot electron-beam bunch length measurements.
We report subpicosecond electro-optic measurements of the length of individual relativistic electron bunches. The longitudinal electron-bunch shape is encoded electro-optically on to the spectrum of a chirped laser pulse. The electron-bunch length is determined by analyzing individual laser-pulse spectra obtained with and without the presence of an electron bunch. Since the length of the chirpe...
متن کاملMeasurement of Bunch Length Using Intensity Interferometry
Abstract Intensity interferometry is one of the most conventional methods for measuring the length of a short light pulse (from ps to sub-ps). We attempted to apply this method to the measurement of bunch length at the Photon Factory. We tested both the second-harmonic autocorrelation method and the two-photon interference method. With both methods, we observed the autocorrelation signal of the...
متن کاملBunch Length and Impedance Measurements at Spear3
Streak camera measurements were made at SPEAR3 to characterize longitudinal coupling impedance. For the nominal optics, data was taken at three rf voltages and a single-bunch current range of 0-20mA. Both bunchcentroid phase shift and bunch lengthening were recorded to extract values for resistive and reactive impedance. An (R+L) and a Q=1 model were then back-substituted into the Haissinski eq...
متن کاملBunch Compression for a Short-Pulse Mode in Cornell’s ERL
The production of ultra-short x-rays in Cornell’s Energy Recovery Linac (ERL) requires electron bunch lengths of less than 100fs with minimal transverse emittance growth and energy spread. Because the linac consists of two sections separated by an arc, CSR forces limit the bunch length in the linac, and bunch compression has to be done after acceleration. Creation of such short bunches requires...
