Description
Chiral Belle is a project proposed to expand the capabilities of SuperKEKB and the physics goals of Belle II by injecting polarized electrons into the High Energy Ring (HER) to make left-right asymmetry measurements. As part of the R&D and feasibility studies of this project, we are developing a proposal to inject and transport transversely polarized electrons into the HER and measure the polarization lifetime.The polarization will be measured as a function of time without Compton polarimetry using the well-established Touschek lifetime approach. Ideally, the Touschek polarization lifetime experiment will include studies of beam-beam effects and a beam energy scan. The results of this Touschek polarization lifetime experiment will inform us of the feasibility of the Chiral Belle project and a measurement of the beam energy. The status of this development work will be presented.
