基于eRHIC的ERL梁-梁研究

Beam-beam study of ERL based eRHIC

Y. Hao, V. N. Litvinenko, V. Ptitsyn

摘要:

eRHIC是BNL提出的基于ERL的电子-离子对撞机(EIC)中的束-束效应,具有几个独特的特征,将其与强子对撞机和轻子对撞机中的束-束效应区分开来。利用电子束仅使用一次的事实,我们预计亮度将比具有类似参数的环-环碰撞方案大10倍。然而,如果不进行适当的处理,电子和强子束的质量可能会受到束-束相互作用的影响而下降甚至损失。讨论了电子束的扰动和失配效应、离子束的扭结不稳定性和噪声加热等有害效应及其可能的对策。

英文摘要:

Beam-beam effects in eRHIC, the proposed ERL-based Electron-Ion Collider (EIC) at BNL, have several unique features distinguishing them from those in hadron-colliders and lepton-colliders. Taking the advantage of the fact that the electron beam is used only once, we expect the luminosity to be 10 times greater than for the ring-ring collision scheme with similar parameters. However, without instituting proper treatments, the quality of electron and hadron beams can undergo degradation or even beam loss, driven by the beam-beam interactions. We will discuss the harmful effects, including the disruption and mismatch effect of the electron beam, the kink instability and the noise heating of the ion beam and the possible countermeasures.
