Contribution

It proposes and evaluates the feasibility of repurposing Tevatron magnets for new injector options for the HE-LHC, highlighting their potential performance benefits.

Findings

Tevatron magnets could be suitable for HE-LHC injectors.

Performance expectations inform design choices for new accelerators.

Two main injector options are outlined and compared.

Abstract

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.
