Seminarium Fizyki Wielkich Energii

In the talk the following subjects will be tackled: basics of the spin-dependent deep inelastic scattering; status of spin-dependent parton distribution measurements and of tomographic imaging of the nucleon; need of higher energies and higher luminosities; features of the planned Electron-Ion Collider and its detectors; possible new phenomena in the now-unexplored kinematic regime reached by EIC.Electron-Ion Collider, a planned new machine to be located in the USA (BNL or JLab), will start operation about 2028.Collision centre-of-mass energy will be of the order of that at HERA but polarisation of electron, proton and light-ion beams, wide variety of heavy-ion beams, up to 1000 times increase in luminosity and wide energy variability will greatly exceed the capabilities of HERA.
