Application of hot isostatic pressing (HIP) technology to diffusion bond refractory metals for proton beam targets and absorbers at CERN / Descarrega, Josep Busom (CERN) ; Calviani, Marco (CERN) ; Hutsch, Thomas (Fraunhofer Inst., Dresden) ; López Sola, Edmundo (CERN) ; Fontenla, Ana Teresa Pérez (CERN) ; Marcone, Antonio Perillo (CERN) ; Sgobba, Stefano (CERN) ; Weißgärber, Thomas (Fraunhofer Inst., Dresden)
A target assembly, composed of several collinear molybdenum (Mo)‐based and tungsten (W)‐based cylindrical blocks, will reside in the core of the new beam dump facility (BDF) being designed at the European Laboratory for Particle Physics (CERN). The target blocks will be protected from the cooling water erosion‐corrosion by a tantalum (Ta)‐based cladding.In order to obtain intimate and reliable bonding between the several cylinders composing each target block and with the cladding, hot isostatic pressing (HIP) assisted diffusion bonding technique was explored.

First prototypes of the new design of the CERN's antiproton production target / Torregrosa Martin, Claudio Leopoldo (CERN) ; Calviani, Marco (CERN) ; Solieri, Nicola (CERN) ; Espadanal, Joao Canhoto (CERN) ; Perillo‐Marcone, Antonio (CERN) ; Ferriere, Romain (CERN) ; Fornasiere, Elvis (CERN) ; Descarrega, Josep Busom (U. Exeter) ; Dickinson, Benjamin (U. Exeter)
For antiproton production at CERN, high‐energy (26 GeV/c), intense, and short proton beams are impacted into a small rod-target core-made of a dense metal. Temperature rises in the order of 2000°C, and subsequent dynamic stresses of several gigapascals are induced in this rod every time it is impacted by the primary proton beam. [...]

A Beam Dump Facility (BDF) at CERN – The Concept and a First Radiological Assessment / Ahdida, Claudia Christina (CERN) ; Avigni, Pietro (CERN) ; Casolino, Mirkoantonio (The Barcelona Institute of Science and Technology (BIST) (ES)) ; Calviani, Marco (CERN) ; Busom Descarrega, Josep (CERN) ; Canhoto Espadanal, Joao Pedro (CERN) ; Grenard, Jean-Louis (CERN) ; Jacobsson, Richard (CERN) ; Kershaw, Keith (CERN) ; Lamont, Mike (CERN) et al.
The Beam Dump Facility (BDF) Project, currently in its design phase, is a proposed general-purpose fixed target facility at CERN, dedicated to the Search for Hidden Particles (SHiP) experiment in its initial phase and whose aim is to fully absorb the high intensity 400 GeV/c SPS beam. The BDF target complex would be located underground at a depth of about 10 m and is designed to contain most of the cascade generated by the primary beam interaction. [...]
