Spectral Fluctuations of Incoherent Radiation and Measurement of Longitudinal Bunch Profile
نویسندگان
چکیده
A method for measurement of ultrashort beam current profile Ib(t) is proposed that is based on detecting fluctuations of the spectral intensity P (ω) of single bunch incoherent radiation. We show that the variance of the Fourier transform of the spectrum is proportional to the convolution function of the beam current. After the convolution function is found, using phase retrieval technique one can restore the shape of the pulse in many practical cases.

Measurement of Electron-Beam Bunch Length and Emittance Using Shot-Noise-Driven Fluctuations in Incoherent Radiation
Longitudinal and transverse phase space information has been obtained from a statistical analysis of fluctuations in the radiation spectrum of an electron bunch. Uncorrelated shot noise fluctuations in longitudinal beam density result in incoherent radiation with a spectrum that consists of spikes, with width inversely proportional to the bunch length. Measurements were performed at l 620 nm on...
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...

Radiation generated by the passage of a monoenergetic electron bunch above the surface wave excited in plane interface between homogeneous media with different dielectric constants is investigated. For the surface wave of general profile the radiation intensity is expressed via the radiated power from a single charge and bunch form factor. Various types of transverse and longitudinal distributi...
متن کاملSimultaneous Detection of Longitudinal and Transverse Bunch Signals at Anka
The ANKA storage ring offers different operation modes including the short-bunch mode with bunch lengths tuned down to a few picoseconds. This can lead to the occurrence of micro-bunching instabilities coupled to the emission of coherent synchrotron radiation (CSR) in so-called ’bursts’. To study this CSR instability we use several turn-by-turn enabled detector systems to synchronously measure ...
متن کاملTemporal evolution of longitudinal bunch profile in a laser wakefield accelerator
We present single-shot measurements of the longitudinal bunch profile from a laser-wakefield accelerator with sub-fs resolution, based on detection of coherent transition radiation in a broad spectral range. A previously developed phase retrieval algorithm enables reconstruction of the bunch profile without prior assumptions about its shape. In this study, a variable-length gas target is used t...
