Ion operation and beam losses

Speaker

Dr Simone Gilardoni (CERN)

Description

The electromagnetic collisions of Lead ions can change the ions charge state due to electron capture via pair production (Bound-Free Pair Production ). Many electron-positron pairs are created in the intense electromagnetic fields of the nuclei. In some cases, the electron is created in a bound-state of one nucleus. These wrongly charged ions are lost in the dispersion suppressor regions, and may lead to a magnet quench when LHC operates at the nominal luminosity and at collision energy. After a brief description of the Bound-Free Pair Production process, a first Monte Carlo evaluation of the energy deposition induced by such losses is discussed.
