More parts of the muon delivery ring
I don't know what this is. It says something about "Debuncher" on the top but that's just a reference to what this entire ring used to be in the Tevatron days, I think (agni.phys.iit.edu/~vpa/fnaldebuncher.html), when this was part of the antiproton production system. Making antiprotons in large numbers was really hard -- I once heard them referred to as "the most expensive stuff on earth, by weight". That's one reason the LHC decided to use proton-proton collisions.
