  Two injector accelerator options for HE-LHC of p+ - p+ collisions at 33 TeV
cms energy are briefly outlined. One option is based on the Super-SPS (S-SPS)
[1] accelerator in the SPS tunnel, and the other one is based on the LER
(Low-Energy-Ring) [2] accelerator in the LHC tunnel. Expectations of
performance of the main arc accelerator magnets considered for the construction
of the S-SPS and of the LER accelerators are used to tentatively devise some
selected properties of these accelerators as potential injectors to HE-LHC.
