Production of gamma rays by pulsed laser beam Compton scattering off GeV-electrons using a non-planar four-mirror optical cavity
T. Akagi, S. Araki, J. Bonis +28
As part of the positron source R&D for future colliders and Compton based compact light sources, a high finesse non-planar four-mirror Fabry-Perot cavity has recently bee…
Polarization induced instabilities in external four-mirror Fabry-Perot cavities
F. Zomer, Y. Fedala, N. Pavloff +2
Various four-mirror optical resonators are studied in the perspective of realizing passive stacking cavities. A comparative study of the mechanical stability is provided. The polar…
PHIL photoinjector test line
M. Alves, C. Arnault, D. Auguste +30
LAL is now equiped with its own platform for photoinjectors tests and Research and Developement, named PHIL (PHotoInjectors at LAL). This facility has two main purposes: push the l…
Non-planar four-mirror optical cavity for high intensity gamma ray flux production by pulsed laser beam Compton scattering off GeV-electrons
J. Bonis, R. Chiche, R. Cizeron +17
As part of the R&D toward the production of high flux of polarised Gamma-rays we have designed and built a non-planar four-mirror optical cavity with a high finesse and operated it…
Design of a Polarised Positron Source Based on Laser Compton Scattering
S. Araki, Y. Higashi, Y. Honda +32
We describe a scheme for producing polarised positrons at the ILC from polarised X-rays created by Compton scattering of a few-GeV electron beam off a CO2 or YAG laser. This scheme…
High flux polarized gamma rays production: first measurements with a four-mirror cavity at the ATF
Nicolas Delerue, J. Bonis, Iryna Chaikovska +27
The next generation of e+/e- colliders will require a very intense flux of gamma rays to allow high current polarized positrons to be produced. This can be achieved by converting p…
