Özet:

Construction of a new 9 km long e-ring tangential to the Large Hadron Collider (LHC) has been proposed as an option for QCD-Explorer stage of the Large Hadron electron Collider (LHeC). It is shown that L=1033 cm-2 s -1 can be achieved with 90 MW synchrotron radiation losses. This luminosity value, which coincides with basic version of ERL60LHC, will be sufficient for precise determination of (Parton Distribution Function) PDFs for LHC, as well as exploration of QCD basics, especially small x Björken region up to 10-6 at Q2 ≈ 1 GeV2 . In addition, some comments on basic and upgraded versions of ERL60LHC are presented as well. It is shown that upgraded ERL60LHC version with L=1034 cm-2 s -1 requires high wall plug power exceeding 160 MW.
