Gersemi is a vertical cryostat system for testing superconducting magnets and cavities located at the FREIA Laboratory, Department of Physics and Astronomy, Uppsala University, Sweden.
The facility allows users to characterize their devices in either saturated or sub-atmospheric liquid helium baths, with a diameter of 1.1m and a height of 2.8m. The range of operation is 1.8 to 4.5~K.
A project based at Gersemi is expected to last typically for three weeks. It is estimated that the installation of equipment will take one week, followed by a week of cooling and measurement, and finally a week to warm up the facility so equipment can be removed.
