Initiated through the Physics Beyond Colliders (PBC) Study Group there is a strong interest from the scientific community to exploit the full intensity potential of the Super Proton Synchrotron (SPS) at CERN for Fixed Target physics experiments before the end of this decade. With the ECN3 cavern in the North Area (NA) identified as a suitable candidate location for a future high-intensity experimental facility compatible with a large variety of experiments, the new PBC ECN3 Beam Delivery Task Force was mandated to assess the feasibility of delivering a slow extracted beam of up to 4x10^19 protons per year at 400 GeV. This contribution summarises the conclusions of the multifaceted beam physics and engineering studies that have been carried out recently to understand the present intensity limitations and to find technical solutions to meet the request for higher intensity in the NA transfer lines towards ECN3. The necessary modifications to the beam lines, the primary target area, beam instrumentation and intercepting devices, as well as the relevant infrastructure and services are outlined, along with a timeline compatible with the NA consolidation project that is already underway.

The LHC beam dump system was developed to safely and reliably dispose of the LHC beams at the end of physics fills or in case of emergency aborts. The beams are extracted by means of kicker magnets, deflecting the beams horizontally, and septa, which provide a vertical kick. The system must be able to cope with rare failure scenarios, such as an asynchronous beam dump, where the rise time of the extraction kickers is not synchronized with the 3 $\mu s$ long particle-free abort gap. This type of event would lead to bunches impacting on downstream accelerator equipment if not properly absorbed by a system of beam-intercepting devices. In the High Luminosity-LHC (HL-LHC) era, the protection absorbers have to withstand significantly higher bunch intensities of up to $2.3\cdot10^{11}$ protons. In this paper, we study the robustness and protection efficiency of the septum protection absorbers for HL-LHC operation. In particular, we present energy deposition simulations for the absorber blocks and downstream equipment and define the required absorber upgrades for HL-LHC.
