  The first LHC Pb ion run took place at 1.38 A TeV/c per beam in autumn 2010. After a short period of running-in, the injector chain was able to fill the collider with up to 137 bunches per ring, with an intensity of 108 Pb ions/bunch, about 50% higher than the design value. This yielded a luminosity of 3E25 Hz/cm2, allowing the experiments to accumulate just under 10 inverse microbarn each during the four week run. We review the performance of the individual links of the injector chain, and address the main issues limiting the LHC luminosity, in view of reaching 1026 Hz/cm2 in 2011, and substantially beyond when the LHC energy increases after the long shutdown in 2013-14.

CERN has 2 operational primary beam ion sources, that are presently used for the production of beam for LHC as well as several other facilities. Protons are produced by a duoplasmatron source, and ions from the GTS-LHC ECR ion source. In addition, new sources are required for a new 160MeV H Linac, and development has been made on a high power RF plasma generator which could serve for a future high power Linac. In this report, the present status will be given, along with operational statistics and experience for the operation sources, and the development programme reported for the future sources.
