“…Furthermore, positron beams offer the possibility of alternative tests of the Standard Model of particle physics through the search of a dark photon, the precise measurement of electroweak couplings, and the investigation of charged lepton flavor violation. Perspectives on an experimental program with high duty-cycle positron beams at JLab may be found in [1,2].…”

Nuclear physics experiments requiring spin polarized positron beams are being proposed at the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Laboratory. This workshop proceedings describes the framework for implementing polarized positron beams at CEBAF and highlights some of the main technical challenges. Specifically, a new polarized positron injector is needed, where the positron beam polarization is created from the bremsstrahlung of an intense continuous-wave (CW) spin polarized electron beam.

“…Jefferson Lab aims to develop a capability to generate a spin-polarized, c.w. positron beam for injection into the main CEBAF accelerator and subsequent delivery to the experimental halls [1,2]. The PEPPo method [3] will be used to generate positrons in a target subjected to a spinpolarized electron beam of at least 1 mA, the high current being necessary due to the low yield of the conversion and subsequent capture process.…”

The Ce+BAF project at the Thomas Jefferson National Accelerator Facility intends to develop over the coming years a high-duty cycle, high intensity, and high polarization positron beam to serve a unique Nuclear Physics experimental program. It generically comprises the study of the effects of the two- and multi-photon exchange mechanisms, the investigation of the nuclear structure at the nucleonic and partonic scales, and tests of the standard model of particle physics and interactions. This proceedings illustrates this physics program through specific examples and presents the Ce+BAF positron injector concept.
