Description
CERN’s upcoming SPS Beam Dump Facility (BDF), in the framework of the HI-ECN3 project, will host the Search for Hidden Particles (SHiP) experiment to search for physics beyond the standard model. At the core of BDF is a solid, high-Z target designed to safely absorb the \SI{400}{\GeV/c} proton beam and dissipate an average deposited thermal power of 305 kW, while providing secondary particles for SHiP. A helium-cooled tungsten (W) design is being developed as an alternative to the initial design based on water-cooled tantalum-tungsten clad molybdenum alloy and W blocks. The new design improves the physics potential performance while simplifying the operation and maintenance of the annex systems. To validate the new concept, two static helium-filled prototype targets were tested with slow extracted beam in CERN’s TCC2 North Area in 2025. In addition to the details of the helium-cooled design, this contribution outlines the prototype design and manufacture and compares online measurements with calculations, highlighting their relevance to the material testing campaign and final target design. The 2025 tests are complemented with a second beam test campaign ongoing in 2026, employing a new prototype with an active helium cooling system, to further validate the target and cooling system.
