A com­pre­hen­sive, first-of-its-kind ex­per­i­ment (HRMT-14) has been re­cently car­ried out at CERN Hi­Rad­Mat fa­cil­ity on six dif­fer­ent ma­te­ri­als of in­ter­est for Beam In­ter­cept­ing De­vices (col­li­ma­tors, tar­gets, dumps). Both tra­di­tional ma­te­ri­als (Mo, W and Cu al­loys) as well as ad­vanced metal/di­a­mond and metal/graphite com­pos­ites were tested under ex­treme con­di­tions as to pres­sure, den­sity and tem­per­a­ture, lead­ing to the de­vel­op­ment of highly dy­namic phe­nom­ena as shock-waves, spal­la­tion, ex­plo­sions. Ex­per­i­men­tal data were ac­quired, mostly in real time, re­ly­ing on ex­ten­sive em­barked in­stru­men­ta­tion (strain gauges, tem­per­a­ture and vac­uum sen­sors) and on re­mote ac­qui­si­tion de­vices (laser Doppler vi­brom­e­ter and high speed cam­era). The ex­per­i­ment was a suc­cess under all points of view in spite of the tech­no­log­i­cal chal­lenges and harsh en­vi­ron­ment. First mea­sure­ments are in good agree­ment with re­sults of com­plex sim­u­la­tions, con­firm­ing the ef­fec­tive­ness of the ac­qui­si­tion sys­tem and the re­li­a­bil­ity of ad­vanced nu­mer­i­cal meth­ods when ma­te­r­ial con­sti­tu­tive mod­els are com­pletely avail­able. In­ter­est­ing in­for­ma­tion has been col­lected as to ther­mal shock ro­bust­ness of tested ma­te­ri­als.
