Positron sources are critical components of the future linear or circular collider projects. This is essentially due to the very high beam intensity required to achieve a high luminosity. Moreover, positron sources are complex devices, where each stage (production, capture, acceleration, injection strategy) has an impact on the final efficiency of the system. Therefore, the technology and design optimization has to be performed for the whole chain. The French (LAL/IPNL) and Japanese (KEK) groups have a long-standing collaboration on the positron source R&D since several years. Currently, two teams are working to improve the performance of the world’s highest intensity positron source in operation of SuperKEKB which is under commissioning now and design of the positron injector for the e+/e- Future Circular Collider FCC-ee. Final performance of the FCC-ee positron source will definitely benefit from the lessons learned during the SuperKEKB commissioning and operation. French members : I. Chaikovska, R. Chehab, H.
