The emittance preservation in the Beam Delivery System (BDS) is one of the
major challenges in CLIC. The fast detuning of the final focus optics requires
an on-line tuning procedure in order to keep luminosity close to the maximum.
Different tuning techniques have been applied to the CLIC BDS and in particular
to the Final Focus System (FFS) in order to mitigate static and dynamic
imperfections. Some of them require a fast luminosity measurement. Here we
study the possibility to use beam-beam backgrounds processes at CLIC 3 TeV CM
energy as fast luminosity signal. In particular the hadrons multiplicity in the
detector region is investigated.
