i have always thought HRC refers to clinton, however, i think it refers to the hadron collider named alice at cern… the R is the only problem, but im not a physics expert, maybe someone else might figure this out.. but its too similar to not be an answer
"ALICE (A Large Ion Collider Experiment) is a detector dedicated to heavy-ion physics at the Large Hadron Collider (LHC). It is designed to study the physics of strongly interacting matter at extreme energy densities, where a phase of matter called quark-gluon plasma forms."
https://home.cern/science/experiments/alice#:~:text=ALICE%20(A%20Large%20Ion%20Collider,called%20quark%2Dgluon%20plasma%20forms.
The detector sits in a vast cavern 56 m below ground close to the village of St Genis-Pouilly in France, receiving beams from the LHC.
so is there another HRC detector somewhere, the US maybe? SA may not always refer to saudi arabia either….
