The workshop will investigate the physics potential of a very high energy electron-proton and electron-ion collider with nominal (eP) center-of-mass energy of 9 TeV, a factor of 30 higher than HERA. The workshop will be over 2 days, 1st and 2nd June 2017, in MPI Munich, starting at 9am on the 1st and finishing by 16:00 on the 2nd. The basis for the accelerator concept is proton-driven plasma wakefield acceleration of electrons, and this approach will be reviewed. A number of invited speakers will cover aspects of QCD and the behavior of high-energy cross sections in general. The sensitivity to physics beyond the Standard Model will also be described. Further contributions are also greatly encouraged; we have purposefully left significant free time in the agenda for additional contributions and discussions. There will be participation fee of 50,- Euro which will cover the lunches in the MPP canteen, the coffee breaks as well as a social dinner in the evening of June 1.

There will be a joint reception for participants in the Workshop and Symposium following the Symposium presentations.
