No, it succeeded in confirming the existence of the Higgs boson. In fact, that's largely the reason Higgs and Englert were awarded the Nobel Prize in Physics in 2013.
Wow, I misread the OPs comment as the LHC also and thought I was experiencing the mandela effect haha.
No the LHC is a Large Hadron Collider, the previous collider was LEP a Large Electron Proton collider. They plan to build a linear electron proton collider similar to SLAC at some point.
Positron (the antimatter counterpart to the electron) not Proton (the positive particle in the nucleus of ordinary atoms).
