本文给出了2015年大型强子对撞机启动的基准参数。在LS1期间，许多系统都进行了升级，2015年大型强子对撞机将以比以前更高的能量运行，并采用更严格的灌装方案。因此，2015年的调试阶段可能不会像2012年那样顺利。拟议的启动配置将重点放在可行性而不是峰值性能上，并包括运营不确定性的利润率。取而代之的是，一旦获得了BEAM经验和更好的机器知识，就可以设想推动$\beta^*$和性能的提升。在这篇文章中，重点是准直设置和$\beta^*$中的REACH-其他参数在这些会议的其他论文中有更深入的讨论。
This paper shows the baseline LHC machine parameters for the 2015 start-up. Many systems have been upgraded during LS1 and in 2015 the LHC will operate at a higher energy than before and with a tighter filling scheme. Therefore, the 2015 commissioning phase risks to be less smooth than in 2012. The proposed starting configuration puts the focus on feasibility rather than peak performance and includes margins for operational uncertainties. Instead, once beam experience and a better machine knowledge has been obtained, a push in $\beta^*$ and performance can be envisaged. In this paper, the focus is on collimation settings and reach in $\beta^*$---other parameters are covered in greater depth by other papers in these proceedings.
