轻子散射实验是探索核子与原子核结构的理想工具。中国电子离子对撞机(Electron Ion Collider in China,EicC)建议书设想在已开建的强流重离子加速器装置(High Intensity heavy ion Accelerator Facility,HIAF)的基础上,升级质子束流为20 GeV的极化束流,并建造2.8~5 GeV极化电子束流,从而实现质心系能量为15~ 20 GeV的双极化电子-离子对撞。EicC设计的亮度为(2~4)×10~(33) cm~(–2)·s~(–1),质子束流极化率达到70%,电子束流极化率达到80%。该装置除了能提供极化轻离子束流(例如:氦-3)外,也可产生非极化重离子束流(碳-12 ~铀- 238)。EicC将聚焦核子海夸克部分子结构、原子核物质结构与性质、奇...

Lepton scattering is an established ideal tool for studying inner structure of microscopic particles such as nucleons as well as nuclei.As a future high energy nuclear physics project,an Electron-ion collider in China(EicC)has been proposed.It will be constructed based on an upgraded heavy-ion accelerator,High intensity heavy-ion accelerator facility(HIAF)which is currently under construction,together with an additional electron ring.The proposed collider will provide highly polarized electrons(with the polarization~80%),protons and Helium-3(bo...
