High-intensity and high-brightness beams are key ingredients to maximize the integrated luminosity of the LHC and exploit its full potential. This contribution will describe the optimization of the beam and machine parameters to maximize the integrated luminosity for the LHC experiments, by taking into account the expected intensity and brightness reach of the LHC and its injector chain and the capabilities of the detectors for the next run and foreseen upgrade scenarios.

For the production of the LHC type beams, but also for the high intensity ones, the budget allocated to losses in the CERN injector chain is maintained as tight as possible, in particular to keep as low as possible the activation of the different machine elements. Various beam dynamics effects, like for example beam interaction with betatronic resonances, beam instabilities, but also reduced efficiency of the RF capture processes or RF noise, can produce losses even on a very long time scale. The main different mechanisms producing long term losses observed in the CERN injectors, and their cure or mitigation, will be revised.
