Abstract

New advanced cryogen-free superconducting mini-gap undulators are capable of supplying high-energy photons required by experiments in medium energy storage rings. ACCEL´s new cryogen-free superconducting undulators pave the way for these easy-to-use high-field insertion devices. The magnet cold mass is cooled down below 4 K without even intermediate use of any cryogenic agent. The cooling power is provided exclusively by multistage cryocoolers and a sophisticated cryogenic design. The cryogenic concept as well as thermal behavior of the first industrial device delivered in January 2004 will be presented along with the field quality measurements.
