9 Breakthroughs CLOUD Particle size Aerosol nucleation under controlled conditions Atmospheric measurements Time (hours) Nucleation depends on traces of organic vapors (tertiary process) and is sensitive to cosmic rays ionization CLOUD: Irradiation at cosmic level C. Vallee SPC-274 Non-LHC Particle Physics at CERN Atmospheric nucleation rates however not reproduced with H 2 SO 4 + NH 3 only, other (yet unknown) organic compounds needed. More studies ongoing at lower temperature 9

New focussing magnets and CRAB cavities for very high luminosity with luminosity levelling Run 4: Collect data until > 3000 fb
