520 _ _ |a The UNILAC will serve as injector linac for heavy ion beams for the future FAIR, with the commissioning being anticipated in 2025. One of the crucial steps in the course of acceleration along the UNILAC is the stripping of the ions by a gas stripper in front of the main linac. Its efficiency is decisive in reaching the intensities required and may be increased by more than 50% by introducing hydrogen as stripping target, instead of the nitrogen used so far. This requires the stripper to be operated in a pulsed mode, since otherwise the pumping speed is not sufficient to maintain suitable vacuum conditions. The proof of principle was demonstrated in 2016*. A dedicated project aims for a setup suitable for routine operation. Main issues are safety, reliability and automated operation. We report on the development done since 2016 and give an overview of the realisation coming within the next few years. Results from systematic measurements on the properties of the valves and their impact on the properties of the stripping target are presented.
