Generation of bright, tunable, polarized y-ray sources by scattering laser pulses from APS electron beams.

摘要

We calculate the performance of possible Advanced Photon Source (APS) {gamma}-ray sources for applications in nuclear physics research. For the APS storage ring, it is possible to generate tagged {gamma}-ray photon fluxes of 10{sup 8}, 0.7 x 10{sup 8}, and 0.3 x 10{sup 8} photons/s at photon energies of 1, 1.7, and 2.8 GeV, respectively. For untagged photons, fluxes higher than 10{sup 8} photons/s are possible for those energies. For the injection booster, an untagged {gamma}-ray photon flux up to 10{sup 8} photons/s at energy ranging from 5 MeV to 1 GeV is possible. This can be achieved using off-the-shelf commercial Ti:Sa laser systems. The photon fluxes predicted here are in general one to two orders of magnitude higher than facilities with similar photon energies.
