Cryogenic Facility (Cryo Center)
The cryogenic facility produces and distributes liquid helium and liquid nitrogen for research at the university. In addition it provides the cryogens for experiments in the test cryostats at FREIA Laboratory. This facility is supported by a grant from the “Knut and Alice Wallenberg Foundation”. It is the key infrastructure needed to develop the superconducting accelerating technology required for many of the future electron and proton accelerators used for particle and material physics such as free electron lasers and high intensity proton accelerators.
Annually approximately 14000 litre of liquid helium and 100000 litre of liquid nitrogen are distributed to users at Uppsala University, the University of Agricultural Sciences and other institutes in Uppsala.
The entrance to the Cryo Centre is either from floor 1 in Ångström or directly from the southern parking lot. A bell and/or phone number are available at the doors, direct entry requires a keycard authorization.
Ordering liquid nitrogen occurs by bringing your dewar to the Cryo Center and complete the order form available. Dewars brought before 9:00 are usually filled the same day. If you are uncertain or have a special request it is recommended that you come down yourself during open hours.
Open for filling of liquid nitrogen: Monday – Friday, 8:00 AM to 9:00 AM.
Open for collection of liquid nitrogen: Monday – Friday, 8:00 AM to 12:00 AM.
Open for filling and collection of liquid helium according prior agreement.
Access with keycard for collection of liquid nitrogen and helium: Monday – Friday, 8:00 AM to 12:00 AM.
Opening hours during Summer 2020
Delivery of liquid nitrogen and helium
Cryo Centrum will continue delivering liquid nitrogen and liquid helium during summer 2020. Delivery will be done every Tuesday and Thursday between 6 July and 31 July, as shown with green in the calendar below.
For the other days that are not shown in the calendar, delivery will be done every working day, as usual.
Filling of dewar takes place between 8:00 and 9:00.
