Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons well nuclei. As a future high energy nuclear physics project, Electron-ion collider in China (EicC) has been proposed. It will be constructed based on upgraded heavy-ion accelerator, High Intensity Accelerator Facility (HIAF) which currently under construction, together with new electron ring. The proposed provide highly polarized electrons (with polarization $\sim$80%) and protons $\sim$70%) variable center mass energies from 15 to 20 GeV the luminosity (2-3) $\times$ 10$^{33}$ cm$^{-2}$ s$^{-1}$.

The Electron-Ion Collider
The future Electron-Ion Collider (EIC) is a proposed new facility to collide high-energy electrons with beams of polarized protons/light nuclei and unpolarized nuclei. We overview the goals of the project and key measurements at the EIC. We also briefly comment on recent developments of the project.
متن کاملAn Electron-Ion Collider at Jefferson lab
As explained in the oral presentation [1], the original plans for an electron-ion collider (ELIC) at Jefferson Lab involved the construction of two figure-of-eight rings, intersecting at up to four collision points, with a proton energy of 30-225 GeV (30-100 GeV/A for ions up to Pb) and electrons (and positrons) from 3 to 9 GeV [2]. Since the construction of such a facility must await completio...
متن کاملELectron - Ion Scattering in a storage ring ( eA collider ) – ELISe
The ELISe experiment will be part of the installations envisaged at the NESR for FAIR. It offers worldwide unique opportunities to scatter electrons off exotic nuclei. Physics opportunities For all stable nuclei, it has been shown [1] that the central densities are about the same (≈ 0.17 nucleons/fm) and that the matter density radius is roughly proportional to the atomic number to the power of...
متن کاملe+A physics at a future Electron-Ion Collider
s = 63 158 (40 110) GeV/A for e+p (e+A) collisions. Whilst gluon distributions have been studied extensively in nucleons at HERA, there is very little information on them for x < 0.1 in nuclei. The rapid increase in the gluon momentum distribution at low-x in nucleons found at HERA, if not tamed, leads to the violation of the Froissart Unitarity Bound at small-x. This can be achieved in non-lin...
