SPring-8 LEPS2 beamline: A facility to produce a multi-GeV photon beam via laser Compton scattering
نویسندگان
چکیده
We have constructed a new laser-Compton-scattering facility, called the LEPS2 beamline, at 8-GeV electron storage ring, SPring-8. This facility provides linearly polarized photon beam in tagged energy range of 1.3--2.4 GeV. Thanks to small divergence low-emittance storage-ring electrons, has size (sigma) suppressed about 4 mm even after it travels 130 m experimental building that is independent ring and contains large detector systems. beamline designed achieve intensity higher than first SPring-8 by adopting simultaneous injection up four high-power laser beams increasing transmittance for long photon-beam path 77%. The under operation hadron photoproduction experiments.

Photon plasma–wave interaction via Compton scattering
The Kompaneets theory of photon kinetic evolution due to the Compton effect in the absence of absorption and emission is extended to the case of the Vlasov plasma wave oscillations. Under the assumption that the electron distribution function at equilibrium is perturbed by a solution of the linearised Vlasov equation in the long-wavelength limit, a solution of the Kompaneets kinetic equation fo...
متن کاملTHE EXPERIMENTAL CHALLENGE OF VIRTUAL COMPTON SCATTERING ABOVE 8 GeV
We discuss the experimental issues confronting measurements of the virtualCompton-scattering (VCS) reaction ep→epγ with electron beams of energy 6 – 30 GeV. We specifically address the kinematics of deeply-virtual-Comptonscattering (deep inelastic scattering, with coincident detection of the exclusive real photon nearly parallel to the virtual photon direction) and large transverse momentum VCS...

The SPring-8 beamline control system is now taking part in the control of the insertion device (ID), front end, beam transportation channel and all interlock systems of the beamline: it will supply a highly standardized environment of apparatus control for collaborative researchers. In particular, ID operation is very important in a third-generation synchrotron light source facility. It is also...

Nowadays, three-dimensional structure of protein becomes important to understanding and application of molecular mechanisms in enzyme reaction, signal transduction and other various biochemical processes. The amount of the information is now growing quantitatively and qualitatively, supported in part by the technical development of macromolecular crystallography. In the development, brilliant s...
متن کاملLaser beam-electron Compton scattering: technology and applications
The goal of this presentation is to introduce the properties and scientific interests of the laser beam-electron beam Compton scattering. There are many possible applications for this process but the main technical difficulty is the requested very high laser beam average power. The various solutions that are presently worked out to provide the requested average power will be reviewed as well as...
