在电子-离子对撞机上进行的亮度测量

Challenging luminosity measurements at the Electron-Ion Collider

Krzysztof Piotrzkowski

摘要:

在未来的电子-离子对撞机(EIC)上,利用韧致辐射过程精确测定绝对光度将是非常困难的,本文讨论了它的三个主要挑战。首先,由于所谓的束尺寸效应而引起的韧致辐射率抑制必须得到很好的控制。其次,应减轻巨大的同步辐射通量的影响。第三,巨大的韧致辐射事件率,超过10千兆赫,必须应付。一个基本布局的亮度测量设置在EIC,解决这些问题,提出了初步的探测器技术的选择。最后,对三种方法的不确定性进行了讨论。

英文摘要:

A precise determination of absolute luminosity, using the bremsstrahlung process, at the future Electron-Ion Collider (EIC) will be very demanding, and its three major challenges are discussed herein. First, the bremsstrahlung rate suppression due to the so-called beam size effect has to be well controlled. Secondly, the impact of huge synchrotron radiation fluxes should be mitigated. Thirdly, enormous bremsstrahlung event rates, in excess of 10 GHz, have to be coped with. A basic layout of the luminosity measurement setup at the EIC, addressing these issues, is proposed, including preliminary detector technology choices. Finally, the uncertainties of three proposed methods are also discussed.
