Diffraction Effects in Coherent Transition Radiation Diagnostics for Sub-mm Bunch Length Measurement*

Electrons crossing the boundary between different media generate bursts of transition radiation. In the case of bunches of N electrons, the radiation is coherent and has an N-squared enhancement at wavelengths related to the longitudinal bunch distribution. This coherent transition radiation has therefore attracted attention as an interceptive charged particle beam diagnostic technique. Many an...

ELECTRON BUNCH LENGTH MEASUREMENT USING COHERENT RADIATION SOURCE OF fs-THz ACCELERATOR AT POHANG ACCELERATOR LABORATORY

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...

A Measurement of High Gain Sase Fel Induced Electron Beam Micro-bunching Using Coherent Transition Radiation

Coherent transition radiation (CTR) was used to study the longitudinal modulations of an electron beam exiting the UCLA/LANL high gain SASE FEL. The induced longitudinal micro-bunching of the electron beam at the exit of the undulator was measured with a frequency domain technique using the CTR emitted when this beam strikes a thin conducting foil. Formalisms for both CTR and SASE theories are ...

Bunch Length Measurements at Ttf Using Coherent Diffraction Radiation

The coherent diffraction radiation technique has been for the first time intentionally employed in the bunch length measurements at the TTF linac. Diffraction radiation (DR) is emitted as a beam passes through an aperture in a highly reflecting screen and, therefore, in contrast to transition radiation (TR), is a really non-intercepting tool a very attractive feature to diagnose high-power beam...

Novel Single Shot Bunch Length Diagnostic Using Coherent Diffraction Radiation

Current beam bunch length monitors that measure the spectral content of beam-associated coherent radiation to determine the longitudinal bunch form factor usually require wide bandwidth detection, Fourier transformation of spectral or interferometric data, phase retrieval algorithms and multiple beam pulses to obtain the bunch length. In this paper we discuss progress in the development of a no...
