The Right Optics Concept for the Right Dimension of the High Luminosity LHC Project / Fartoukh, Stephane (CERN)
While the LHC optics is approaching its limit in terms of beta*, not only bounded, somehow in relative, by the aperture of the existing inner triplets, but also, in absolute, by the match-ability, the flexibility and, at some point (not yet reached) the chromatic aberrations of the corresponding collision optics, the High Luminosity LHC project requests to triple or even quadruple this effort in order to meet the challenging performance target of 250 1/fb per year.
