“…A new junction cavern and extraction tunnel are proposed to be built in the North Area of CERN to house the new beam-line leading protons to the Beam Dump Facility (BDF) complex [4]. A 1.5 m long production target will be located inside the radiation protecting bunker at about 15 metres below ground level.…”

“…The setup consists of a high-density proton target located in the target bunker [7][8][9], followed by a hadron stopper and a muon shield [10]. The target is made of blocks of a titanium-zirconium doped molybdenum alloy (TZM) in the region of the largest deposit of energy, followed by blocks of pure tungsten.…”

The Search for Hidden Particles (SHiP) Collaboration has proposed a general-purpose experimental facility operating in beam-dump mode at the CERN SPS accelerator to search for light, feebly interacting particles. In the baseline configuration, the SHiP experiment incorporates two complementary detectors. The upstream detector is designed for recoil signatures of light dark matter (LDM) scattering and for neutrino physics, in particular with tau neutrinos. It consists of a spectrometer magnet housing a layered detector system with high-density LDM/neutrino target plates, emulsion-film technology and electronic high-precision tracking. The total detector target mass amounts to about eight tonnes. The downstream detector system aims at measuring visible decays of feebly interacting particles to both fully reconstructed final states and to partially reconstructed final states with neutrinos, in a nearly background-free environment. The detector consists of a 50 m long decay volume under vacuum followed by a spectrometer and particle identification system with a rectangular acceptance of 5 m in width and 10 m in height. Using the high-intensity beam of 400 GeV protons, the experiment aims at profiting from the 4 × 10 19 protons per year that are currently unexploited at the SPS, over a period of 5-10 years. This allows probing dark photons, dark scalars and pseudo-scalars, and heavy neutral leptons with GeV-scale masses at sensitivities that largely exceed those of existing and projected experiments. The sensitivity to light dark matter reaches well below the dark matter relic density limits in the range from a few MeV/c 2 up to 200 MeV/c 2 , and it will be possible to study tau neutrino interactions with unprecedented statistics. This paper describes the SHiP baseline experiment setup and the detector systems with performance results from prototypes in test beams. The expected detector performance from simulation is summarised at the end.

“…The authors in [316] interpreted the ALP search result in NOMAD [302] by a LSW-like regeneration method (ALP production in the magnetic field of the beam focusing horn and ALP detection in the magnetic field of the detector) in terms of PASSAT (see the line for PASSAT-NOMAD). They further proposed a realization of PASSAT by recycling the magnets of the CAST or the proposed BabyIAXO experiments (after decommissioned) and placing them at the proposed beam-dump facility [364] at CERN (see the lines for PASSAT-BDF-CAST and PASSAT-BDF-BabyIAXO). Similar proposals were made for DUNE or DUNE-like neutrino facilities [319].…”

We review topics in searches for axion-like-particles (ALPs), covering material that is complementary to other recent reviews. The first half of our review covers ALPs in the extreme environments of neutron star cores, the magnetospheres of highly magnetized neutron stars (magnetars), and in neutron star mergers. The focus is on possible signals of ALPs in the photon spectrum of neutron stars and gravitational wave/electromagnetic signals from neutron star mergers. We then review recent developments in laboratory-produced ALP searches, focusing mainly on accelerator-based facilities including beam-dump type experiments and collider experiments. We provide a general-purpose discussion of the ALP search pipeline from production to detection, in steps, and our discussion is straightforwardly applicable to most beam-dump type and reactor experiments. We end with a selective look at the rapidly developing field of ultralight dark matter, specifically the formation of Bose-Einstein Condensates (BECs). We review the properties of BECs of ultralight dark matter and bridge these properties with developments in numerical simulations, and ultimately with their impact on experimental searches.
