By Roger Ruber, Kevin Pepitone & Akira Miyazaki - Uppsala University in Sweden has been a valuable partner to CERN since the Laboratory’s foundation. In the 1950s, Uppsala, having just constructed its own cyclotron, contributed to the development of the very first accelerator at CERN, the Synchrocyclotron. In the 1980s, CERN assisted Uppsala in constructing a proton and heavy-ion accelerator and cooler-storage ring named CELSIUS and, in the mid-2000s, Uppsala assisted in the development and operation of the CLIC CTF3 test facility at CERN.

Now, Uppsala University is upgrading its FREIA Laboratory, initially constructed for the ESS project, to test superconducting magnets and crab cavities for the HL-LHC, CERN Bulletin.
