LHeC
The LHeC (short for Large Hadron-Electron Collider ) is an accelerator project that is intended to significantly expand the existing LHC storage facility - currently the most powerful accelerator at the CERN Research Institute in Geneva - not only in terms of performance, but also in terms of the range of collisions investigated: Instead of the hadron-hadron collisions as before, proton-electron collisions should also be investigated, as with the decommissioned Hamburg electron-proton accelerator HERA . This is e.g. B. promising for the study of the Higgs boson .
The LHeC concept essentially consists in supplementing the existing LHC ring with two superconducting electron linear accelerators with a length of 1008 m arranged tangentially to it. In addition to the two opposing proton beams (or heavy ion beams) of the LHC, electron beams can then be accelerated to 60 GeV. The electron beam can then be “decelerated” again so that the energy is recovered (“energy recovery linac”, ERL). It is planned to record electron-proton data and, as before, proton-proton data at the same time.
