The EIC’s ability to collide high-energy electron beams with high-energy
ion beams will provide access to those regions in the nucleon and nuclei
where their structure is dominated by gluons. Moreover, polarized beams
in the EIC will give unprecedented access to the spatial and spin
structure of gluons and sea-quarks in the proton and light nuclei.
The EIC will be an unprecedented collider with luminosities 2-3 orders
of magnitude higher than that at HERA over a very wide range of
center-of-mass energies from 20 up to 140 GeV, while accommodating
highly polarized (~70%) electron and nucleon beams. Equally demanding
are the requirements for physics detector(s) that will be needed to
carry out the compelling EIC physics program: hermetic coverage in
tracking, calorimetry and particle ID within a wide pseudorapidity
range, substantial angular and momentum acceptance in the hadron-going
direction, as well as high quality hadronic calorimetry among others.
In my talk I will give an overview of the detector requirements and
current general-purpose detector concepts, providing a connection
between physics requirements, simulations and the ongoing EIC Detector
R&D Program.
