Recently the proof-of-principle experiments were carried out where a circularly polarized beams of -quanta with energy MeV have been produced in order to generate longitudinal-polarized positrons [1, 2].
In [1] the circularly polarized -beam was obtained via Compton backscattering of circularly polarized laser photons by an electron beam with energy 1.28 GeV.For real positron sources a...

With the ILC baseline design polarized positrons will be delivered.
To optimize and control the positron beam, also the polarization measurement
close to the creation point is recommended.
Taking into account the positron beam parameters at the source,
possible methods for polarimetry include a Compton transmission
polarimeter (directly downstream the capture section) and a Bhabha...
