Abstract
Construction of the TESLA linear electron-positron collider tangentially to the HERA proton
ring will provide a number of new facilities for particle and nuclear physics research. In this
paper main parameters and physics goals of eA, γA and FEL γA colliders, as well as fixed target
experiments are discussed.
HERA based eA collider. Collisions of Ee=30 GeV electrons with different nuclei accelerated
in HERA proton ring (EA=Z 0.92 TeV) will give opportunity to investigate parton distributions
in nuclear medium. Especially, exploration of the region of very small x at Q2>1 GeV2 is very
important.
TESLA* HERA based eA collider. In this case Ee=250 GeV electrons from TESLA will be
used, which results in essential extension of the x-range.
TESLA*HERA based γA collider. Using the Compton backscattering of the laser beam off the
electron beam from TESLA one can form the high-energy y-beam (Eγ≈200 GeV). The yA
collider will give a unique opportunity to investigate a number of important phenomena
(including the region of extremely small xg) in a best manner.
TESLA*HERA based FEL yA collider. Ultrarelativistic ions will see the TESLA FEL (Free
Electron Laser) beam as a beam of MeV energy photons. This will give a unique opportunity to
investigate “old” nuclear phenomena in rather unusual conditions.
Fixed target experiments. The scattering of the polarised electron and photon beams from
TESLA on polarised nuclear targets will give opportunity to investigate the spin contents of
nucleons.
ELFE@DESY: An Electron Laboratory For Europe at DESY. Using TESLA and HERA a
high luminosity quasi-continuous electron beam (Ee= 15-5-25 GeV) suitable for nuclear physics
experiments can be produced. In addition, using a 2660 Ao laser a 25 GeV electron beam can be
converted into a photon beam with energy up to 16 GeV.
