Future e+e− colliders will need positron sources that stretch present technical capabilities. The project teams for these proposed colliders are working to extend these capabilities. A positron source encompasses many elements: an electron driver, production target, lattice optics, capture section, damping ring(s), injection/extraction short-pulse kickers, an emittance preserving complex delivery system, specific injection specifications, and (perhaps) polarization. The required technical parameters need to accommodate many beam aspects including bunch intensities, final emittances, spacings, train lengths, and desired damping times. For this note, the technical requirements for positrons related to bunch charges, number of bunches, damping ring lengths and damping times for the various positron sources for the presently proposed colliders are compared, concentrating on their damping ring specifications.

A special session at eeFACT’22 reviewed the electrical power budgets and luminosity risks for eight proposed future Higgs and electroweak factories (CCC, CEPC, CERC, CLIC, FCC-ee, HELEN, ILC, and RELIC) and, in comparison, for a lepton-hadron collider (EIC) presently under construction. We report highlights of presentations and discussions.
