Abstract
It is shown that if high energy positrons are moving in planar channeling conditions in a bent crystal at a small angle with respect to atomic strings which form the bent channeling planes, the hard part of the spectrum of gamma radiation emitted by the positrons will be highly circularly polarized. This Circularly Polarized String-of-Strings Radiation of Positrons Channeled in Bent Crystal (CP-SOSRPCHBC) can be considered as a circularly polarized coherent bremsstrahlung manifesting itself efficiently from sub-GeV up to TeV and higher positron energies. The possibility to observe the CPSOSRPCHBC at the 500MeV positron beam of Frascati National Laboratory is considered.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
