Some early particle accelerators that more properly did nuclear physics, but existed prior to the separation of particle physics from that field, are also included.
They tended to have very briefly run, inexpensive, and unnamed experiments.
[1] The magnetic pole pieces and return yoke from the 60-inch cyclotron were later moved to UC Davis and incorporated into a 76-inch isochronous cyclotron which is still in use today[1] More modern accelerators that were also run in fixed target mode; often, they will also have been run as colliders, or accelerated particles for use in subsequently built colliders.
