In this paper we review the latest baseline parameters and performance, and study the potential reach of the HL-LHC with pushed optics at the ultimate beam energy. Results in terms of integrated luminosity and effective pile-up density of both the nominal (5.0×10³⁴ cm⁻² s^{−1}) and ultimate (7.5×10³⁴ cm⁻² s^{−1}) levelling operations are discussed PB - JACoW Publishing CP - Geneva, Switzerland SP - 408 EP - 411 KW - operation KW - luminosity KW - optics KW - emittance KW - cavity DA - 2018/06 PY - 2018 SN - 978-3-95450-184-7 DO - 10.18429/JACoW-IPAC2018-MOPML009 UR - http://jacow.org/ipac2018/papers/mopml009.pdf ER -
