Query: ERLC (Twin LC) and LHC/FCC Based eA Colliders   Construction of the ERLC (twin LC) collider tangential to LHC or FCC will
give opportunity to realize eA collisions at multi-TeV center-of-mass energies.
Luminosity estimations show that values comparable with that of ERL60 based eA
colliders are achievable while center of mass energies are essentially higher.
Certainly, proposed eA colliders have great potential for clarifying QCD basics
and nuclear structure.
