Electro-optic technique with improved time resolution for real-time, nondestructive, single-shot measurements of femtosecond electron bunch profiles.
Electro-optic detection of the Coulomb field of a relativistic electron bunch combined with single-shot cross correlation of optical pulses is used to enable single-shot measurements of the shape and length of femtosecond electron bunches. This method overcomes a fundamental time-resolution limit of previous single-shot electro-optic measurements, which arises from the inseparability of time an...
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 کاملSingle-shot Longitudinal Bunch Profile Measurements at Flash Using Electro-optic Detection: Experiment, Simulation, and Validation
At the superconducting linac of FLASH at DESY, we have installed an electro-optic (EO) experiment for singleshot, non-destructive measurements of the longitudinal electric charge distribution of individual electron bunches. The time profile of the electric bunch field is electrooptically encoded onto a chirped titanium-sapphire laser pulse. In the decoding step, the profile is retrieved either ...
متن کاملFemtosecond Resolution Bunch Arrival Time Monitor
A need for femtosecond resolution beam arrival time measurements has arisen with the transition from manypicosecond-long bunches in ring-based accelerators to a few femtosecond-long bunches in high-gain free-electron lasers. Here we present an electro-optical detection scheme that uses the signal of a beam pick-up to modulate the intensity of a femtosecond laser pulse train. By detecting the en...

Companion development of ultrafast electron beam diagnostics capable of noninvasively resolving single bunch detail is essential for the development of high energy, high brightness accelerator facilities and associated beam-based light source applications. Existing conventional accelerators can exhibit timing-jitter down to the 100 femtosecond level which exceeds their single bunch duration cap...
