Accelerator Magnet RD in the Perspective of a LHeC and HE-LHC - Synergy or Competion?

Beyond HL-LHC, CERN has a number of physics options that offer potential and challenges. This contribution dwells on the long-term projects HE-LHC and LHeC to put the magnet R&D at CERN (resistive and superconducting, slow and fast) in a long-term perspective. In particular synergies and parallel roadmaps will be highlighted. We will show how the on-going development (2012-2015) on low-field, high-field, and low-loss magnets can be used towards longer term objectives.
