基于目前欧洲核子研究中心的基础设施，电子-质子对撞机提出了一个质心能量约为9 TeV。一个7 TeV的LHC束流被用作质子驱动器，以产生等离子体韦克菲尔德，然后将电子加速到3 TeV，然后与其他7 TeV的LHC质子束碰撞。虽然对撞机的能量很高，但它的投影积分光度只有10100 pb（-1）。对于这样的对撞机，质心能量比HERA大30倍，对于1 GeV 2的光子虚量Q（2），部分子动量分数x可以低至约10（-8）。高能强子截面的能量依赖性，如总光子-质子截面，它与宇宙射线物理学有协同作用，可以测量和QCD和物质的结构更好地理解在一个区域的影响是完全未知的。在高Q（2）下，超越标准模型的物理学将是可能的，特别是对leptoquark产生的灵敏度显着增加。概述了极高能电子-质子对撞机的这些和其他物理亮点。
Based on current CERN infrastructure, an electron-proton collider is proposed at a centre-of-mass energy of about 9 TeV. A 7 TeV LHC bunch is used as the proton driver to create a plasma wakefield which then accelerates electrons to 3 TeV, these then colliding with the other 7 TeV LHC proton beam. Although of very high energy, the collider has a modest projected integrated luminosity of 10100 pb(-1). For such a collider, with a centre-of-mass energy 30 times greater than HERA, parton momentum fractions, x, down to about 10(-8) are accessible for photon virtualities, Q(2), of 1 GeV2. The energy dependence of hadronic cross sections at high energies, such as the total photon-proton cross section, which has synergy with cosmic-ray physics, can be measured and QCD and the structure of matter better understood in a region where the effects are completely unknown. Searches at high Q(2) for physics beyond the Standard Model will be possible, in particular the significantly increased sensitivity to the production of leptoquarks. These and other physics highlights of a very high energy electronproton collider are outlined.
