An Rf Bunch-length Monitor for the Slc Final Focus
In preparation for the 1997 SLC run, a novel RF bunchlength monitor has been installed in the SLC South Final Focus. The monitor consists of a ceramic gap in the beam pipe, a 160-ft long X-band waveguide (WR90), and a set of dividers, tapers and microwave detectors. Electromagnetic fields radiated through the ceramic gap excite modes in the nearby open-ended X-band waveguide, which transmits th...
متن کاملELECTRON 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...
متن کاملFemtosecond Single- Bunch Electron Linear Accelerator Based on a Photocathode Rf Gun
A femtosecond single-bunch electron linear accelerator based on a photocathode rf gun was developed in Osaka University for the study of radiation-induced ultrafast physical and chemical reactions. A 32 MeV single electron bunch with bunch length of 98 fs in rms was generated successfully with a magnet bunch compressor, and was used as pump source to study the electroninduced ultrafast reaction...
متن کاملTunneling Ionization Bunch Length Monitor for the Ultrarelativistic Compressed Electron Beams
The electric field intensity of the compressed ultrarelativistic electron beams is approaching GV/m levels, which is sufficient to cause observable tunneling effect in the low band gap materials. In this article the tunneling ionization rate is estimated for the experimentally available electron beam parameters, and a proposed proof of principle experiment is outlined. Tunneling effect has expo...
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...
