Measurement of Bunch Length Using Intensity Interferometry

چکیده
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 bunch envelope. The bunch length measured via twophoton interference method is in good agreement with the value measured by the conventional streak camera technique.

Measurement of Sub-picosecond Bunch Length with the Interferometry from Double Diffraction Radiation Target*
Reliable and precise methods for non-invasive diagnostics of sub-picosecond electron bunches are required for new accelerator facilities (FEL, LWFA, et al.). Measurements of spectral characteristics of coherent radiation generated by such bunches using interferometer allow to determine a bunch length [1]. Here we present a compare experimental study between the measurement from the double diffr...

A Michelson interferometer was installed at the femtosecond (fs) terahertz (THz) Accelerator of Pohang Accelerator Laboratory(PAL) to measure a subpicosecond order electron bunch length. To measure an ultra-short electron bunch length, we use reconstruction process and fast fourier transform. Currently, we are generating THz radiation with the pulse energy of 7μJ by means of coherent transition...
متن کاملObservation of coherent terahertz edge radiation from compressed electron beams
Coherent radiation emitted from a compressed electron bunch as it traverses the sharp edge regions of a magnetic chicane has been investigated at the Brookhaven National Laboratory Accelerator Test Facility. Electron beam measurements using coherent transition radiation interferometry indicate a 100 fs rms bunch accompanied by distinct distortions in energy spectrum due to strong self-fields. T...
متن کاملFluctuational Interferometry for Measurement of Short Pulses of Incoherent Radiation *
A novel method for measuring ultrashort pulses of incoherent radiation is proposed. The method is based on detecting the fluctuations of the visibility of interference fringes in a two-beam interferometer. It is shown that the dispersion of the fluctuations is proportional to the convolution integral of the instantaneous intensity in the pulse. Using statistical analysis of the interference pat...
متن کاملSub-picosecond electron bunch length measurement by terahertz radiation S.Zhang S.Benson D.Douglas M.Shinn and G.Williams
This paper presents the measurement of sub-picosecond relativistic electron beam bunch length by analyzing the spectra of the coherent terahertz pulses through Kramers-Kronig transformation. The results are compared with autocorrelation from a scanning polarization autocorrelator that measures the coherent optical transition radiation. The limitations of the different methods to such a characte...
