Single-shot electron bunch length measurements using a spatial electro-optical autocorrelation interferometer.
A spatial, electro-optical autocorrelation (EOA) interferometer using the vertically polarized lobes of coherent transition radiation (CTR) has been developed as a single-shot electron bunch length monitor at an optical beam port downstream the 100 MeV preinjector LINAC of the Swiss Light Source. This EOA monitor combines the advantages of step-scan interferometers (high temporal resolution) [D...
متن کاملPicosecond Electron Bunch Length Measurement by Electro-optic Detection of the Wakefield
The longitudinal profile of an 10 nC electron bunch of a few picoseconds duration will be measured by electro-optic detection of the wakefield. The polarization of a short infrared probe laser pulse (derived from the photocathode excitation laser) is modulated in a LiTaO3 crystal by the transient electric field of the bunch. The bunch profile is measured by scanning the delay between the laser ...
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 کاملBenchmarking of electro-optic monitors for femtosecond electron bunches.
The longitudinal profiles of ultrashort relativistic electron bunches at the soft x-ray free-electron laser FLASH have been investigated using two single-shot detection schemes: an electro-optic (EO) detector measuring the Coulomb field of the bunch and a radio-frequency structure transforming the charge distribution into a transverse streak. A comparison permits an absolute calibration of the ...
متن کاملBunch - Length and Beam - Timing Monitors in the SLC Final Focus
During the 1997/98 luminosity run of the Stanford Linear Collider (SLC), two novel RF-based detectors were brought into operation, in order to monitor the interaction-point (IP) bunch lengths and uctuations in the relative arrival time of the two colliding beams. Both bunch length and timing can strongly a ect the SLC luminosity and had not been monitored in previous years. The two new detector...
