  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 CERN[1]
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.
