abstract = {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.},
