Visualized: step inside CERN's particle-detecting Compact Muon Solenoid

It's spring maintenance time over at the Large Hadron Collider, and the folks at CERN have seen fit to crack open the Compact Muon Solenoid to get at some of its loose connectors. You see, after three years, 99-percent of the the lead tungstate-based electromagnetic calorimeter's channels are currently operational -- but its keepers think it can do better, working on a less than reliable connection that has the preshower down to a paltry 97-percent. Naturally, they've cracked the thing open and ...
