Generation of Femtosecond Bunch Trains Using a Longitudinal-to-transverse Phase Space Exchange Technique
We demonstrate analytically and via numerical simulations, how a longitudinal-to-transverse phase space manipulation can be used to produce a train of femtosecond electron bunches. The technique uses an incoming transversely-modulated electron beam obtained via destructive (e.g. using a multislits mask) methods. A transverse-to-longitudinal exchanger is used to map this transverse modulation in...
متن کاملSingle-shot method for measuring femtosecond bunch length in linac-based free-electron lasers
There is growing interest in the generation and characterization of femtosecond and subfemtosecond pulses from linac-based free-electron lasers (FELs). In this report, following the method of Ricci and Smith [Phys. Rev. STAccel. Beams 3, 032801 (2000)], we investigate the measurement of the longitudinal bunch profile of an ultrashort electron bunch produced by these FELs. We show that this meth...
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 کاملMulti-bunch Longitudinal Instability due to the Electron Cloud
The mechanism of longitudinal interaction of high-energy positrons of a bunch train and secondary emitted particles of electron cloud is analyzed. We consider the case when electron cloud in solenoidal magnetic field is built mainly due to multipacting process. Positron bunches have to use some amount of their kinetic energy to give electron cloud some temperature. The field, which is responsib...
