The comparison of electron and positron collisions with ions or fix targets has been used at HERA*, ** to explore the nuclear structure and investigate predictions of the Stantard Model. High luminosity and/or a high polarization positron beams are today considered at Jefferson Lab for physics experiments***. The understanding of different physics processes requires both unpolarized and polarized positron beams to unveil the internal structure of nuclei. In this paper, we report on integration schemes of positron beams at the CEBAF and for the proposed JLEIC. We explore possible injection schemes that provide the desired bunch charge and injection bunch pattern for both unpolarized and polarized positrons. For the JLEIC, we also estimate the collider performance in terms of luminosity and polarization.
