Experiment exposing refractory metals to impacts of 440 GeV/c proton beams for the future design of the CERN antiproton production target: Experiment design and online results

[EN] The HRMT27-RodTarg experiment employed the HiRadMat facility at CERN to impact intense 440 GeV proton beams onto thin rods 8 mm in diameter, 140 mm in length, and made of high-density materials such as Ir, W, Ta, Mo, and alloys. The purpose of the experiment was to reduce uncertainties on the C...

The purpose of the experiment was to reduce uncertainties on the CERN antiproton target material response and assess the material selection for its future redesign. The experiment was designed to recreate the extreme conditions reached in the production target, estimated in an increase of temperature above 2000 degrees C in less than 0.5 mu s and a subsequent compressive-to-tensile pressure wave of several gigapascals. The goals of the experiment were (i) to validate the hydrocode calculations used for the prediction of the antiproton target response and (ii) to identify limits and failure mechanisms of the materials of interest. In order to accomplish these objectives, the experiment relied on extensive instrumentation (pointing at the target rod surfaces). This paper presents a detailed description of the experiment as well as the recorded online results which showed that most of the investigated materials suffered internal damage from conditions 5-7 times below the ones present in the AD target. Tantalum, on the other hand, apparently withstood the most extreme conditions without presenting internal cracking.The authors express their gratitude to the HiRadMat facility for its invaluable support during the design and execution of the experiment as well as to all the CERN groups involved, such as BE/OP/SPS, BE/BI/PM, HSE/RP/AS, and EN/MME. In addition, the authors thank CERN's Accelerator Consolidation (ACC-CONS) Project, which financed this work, as well as the funding received through the EuCARD2 FP7 program (Grant Agreement No. 312453) in the context of the HiRadMat facility. Finally, the authors are grateful to Anna Lambert and Louisa Catherall for the English proofreading of this manuscript.American Physical SocietyEuropean CommissionRepositorio Institucional de la Universitat Politècnica de València Riunet20192019-01-07journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://riunet.upv.es/handle/10251/161602reponame:RiuNet.
