dc.description.abstract Antiprotons are produced at CERN by colliding a 26 GeV=c proton beam with a fixed target made of a3 mm diameter, 55 mm length iridium core. The inherent characteristics of antiproton production involveextremely high energy depositions i nside 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 risetemperature 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. es_ES
