Description
The physics program using the polarized low energy electron/positron beam at CE$^+$BAF will require multiple forms of precise beam polarimetry.
The spin dependent synchrotron radiation (SR), called “spin-light,” is a
well known phenomena routinely used to polarize electron/positron beams in
storage rings. The use of spin-light for monitoring beam polarization of
transversely polarized beams was conclusively demonstrated four decades ago. More recently, polarimetry of longitudinally polarized beam was shown to be much more challenging, but feasible for high energy beams. We will explore spin-light based non-invasive polarimetry for low energy transversely polarized electron/positron beams and present the potential range of operation for such a device.
