Description
The Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab (JLab) is the first particle accelerator to employ superconducting radio-frequency (SRF) cavities for generating continuous-wave (CW) high-intensity polarized electron beams. These beams enable detailed investigations of nucleon structure, protons and neutrons, and the strong nuclear force that governs their interactions. Recently, an upgrade opportunity has been explored: the addition of an unpolarized or polarized positron beam. This enhancement would significantly broaden the range of experimental probes and provide data that cannot be obtained using electron beams alone. This talk presents spin rotation design strategies aimed at delivering the desired polarization configurations for both electron and positron beams in low-energy electron–positron physics experiments at CEBAF.
