Sumario:During the LHC proton physics run in 2016 the injectors were regularly providing 25 ns beams, in both the standard and the high brightness, i.e. BCMS, variant. In this paper , the achieved parameters for these two beam production schemes are analysed and compared to the expected performance reach of the LHC injector complex. It is shown that the standard beam could be produced close to the known performance limits, while the high brightness BCMS beams suffered from emittance blow-up especially in the PS. First results from machine development studies addressing this issue are presented, showing the potential for mitigating at least part of the blow-up in the future. An outlook of the expected beam parameters from the injectors in 2017 is given, including also special beam variants like the 8b4e, the 80 bunches and the doublet scrubbing beam.
