Abstract
The Search for Hidden Particles (SHiP) Collaboration has shown that the CERN SPS
accelerator with its 400 GeV c proton beam offers a unique opportunity to explore the Hidden
Sector [1–3]. The proposed experiment is an intensity frontier experiment which is capable of
searching for hidden particles through both visible decays and through scattering signatures from
recoil of electrons or nuclei. The high-intensity experimental facility developed by the SHiP
Collaboration is based on a number of key features and developments which provide the possibility
of probing a large part of the parameter space for a wide range of models with light long-lived superweakly
interacting particles with masses up to O¹10º GeV c2 in an environment of extremely clean
background conditions. This paper describes the proposal for the experimental facility together with
the most important feasibility studies. The paper focuses on the challenging new ideas behind the
beam extraction and beam delivery, the proton beam dump, and the suppression of beam-induced
background.
