Even though many of the experiments leading to the standard model of particle physics were done at large accelerator laboratories in the US and at CERN1 many exciting developments happened in smaller national facilities all over the world. In this report we highlight the history of accelerator facilities in Sweden which was home to the highest-energy cyclotron in Europe for some time in the early 1950s. 1 For a brief history of this story see: V.
