Summary

“Gersemi”, a vertical cryostat to test superconducting magnets and radio-frequency cavities at liquid helium temperatures, will be installed at FREIA Laboratory at Uppsala University, Sweden. With three independent inserts, the same cryostat can be used to test different superconducting equipment at low power: a “vacuum” insert for cavities equipped with a helium vessel, a “bath” insert for cavities (and other equipment) without a helium vessel and a “lambda-plate” insert for magnet testing. Each insert has been designed to be as versatile as possible, making the available space inside the cryostat the main constraint for equipment testing. The cryostat will have an internal diameter of 1.1 m and 4.7 m total height. For magnet testing, “Gersemi” will be able to handle superconducting magnets with a stored energy up to 340 kJ. A valve box to direct the cryogens, a reheater for warming up the output gases and a control system complete the setup. "Gersemi" vertical cryostat is connected to a helium liquefier and recovery system, and in parallel to an existing horizontal cryostat for testing superconducting equipment already operational at FREIA Laboratory.
