Antiprotons are produced at CERN by colliding a 26 GeV=c proton beam with a fixed target made of a 3 mm diameter, 55 mm length iridium core. The inherent characteristics of antiproton production involve extremely high energy depositions inside the target when impacted by each primary proton beam, making it one of the most dynamically demanding among high energy solid targets in the world, with a rise temperature above 2000°C after each pulse impact and successive dynamic pressure waves of the order of GPa's. An optimized redesign of the current target is foreseen for the next 20 years of operation. As a first step in the design procedure, this numerical study delves into the fundamental phenomena present in the target material core under proton pulse impact and subsequent pressure wave propagation by the use of hydrocodes. Three major phenomena have been identified, (i) the dominance of a high frequency radial wave which produces destructive compressive-to-tensile pressure response (ii) The existence of end-ofpulse tensile waves and its relevance on the overall response (iii) A reduction of 44% in tensile pressure could be obtained by the use of a high density tantalum cladding.

“…[176]. Some numerical studies of material damage induced by beam impacts using this failure criterion can be found in the literature ( [164], [166]). As with the previous two models, the P min failure model is implemented in most of the nonlinear commercial codes due to its simplicity and data availability in the literature.…”

The Antiproton Decelerator Target (AD-Target) is a unique device responsible for the production of antiprotons at the European Organization for Nuclear Research (CERN). During operation, intense 26 GeV energy proton beams are impacted into its core, made of a 3 mm diameter rod of a high density material such as iridium, creating secondary particles-including antiprotons-from the nuclear reactions induced in its interior. This thesis delves into the characteristics of antiproton production and in particular in the mechanical response of the target core material, which is exposed to a rise of temperature of ∼ 2000 • C in less than 0.5 µs each time is impacted by the primary proton beam. A coupled numericalexperimental approach has been applied for this purpose. Finalmente, agradecer infinitamente a mi familia, primos y tíos. Y más que a nadie a mis padres y hermana, por su cariño y apoyo incondicional, ahora y siempre. Este doctorado es tan suyo como mío.
