The 28 GHz Ion Source VENUS (versatile ECR for nuclear science) is back in operation after the
superconducting sextupole leads were repaired and a fourth cryocooler was added. VENUS serves as
an R&D device to explore the limits of electron cyclotron resonance source performance at 28 GHz
with its 10 kW gryotron and optimum magnetic fields and as an ion source to increase the capabilities
of the 88-Inch Cyclotron both for nuclear physics research and applications. The development and
testing of ovens and sputtering techniques cover a wide range of applications. Recent experiments on
bismuth demonstrated stable operation at 300 eμA of Bi31+, which is in the intensity range of interest
for high performance heavy-ion drivers such as FRIB (Facility for Rare Isotope Beams). In addition,
the space radiation effects testing program at the cyclotron relies on the production of a cocktail beam
with many species produced simultaneously in the ion source and this can be done with a combi
