Dur­ing CERN’s LS2, sev­eral up­grades were per­formed to beam in­ter­cept­ing de­vices in the frame­work of the HL-LHC Pro­ject. Up­graded equip­ment in­cludes two in­ter­nal beam dumps (TDIS) in­tended for ma­chine pro­tec­tion lo­cated at the in­jec­tion points from the SPS to the LHC. These two de­vices have been as­sem­bled, tested, and in­stalled around LHC Point 2 and Point 8 and are cur­rently ready to get com­mis­sioned with the beam. They are 5.8m-long, three-mod­ule-seg­mented vac­uum cham­bers, with large aper­ture to ac­com­mo­date the in­jected and cir­cu­lat­ing beam and equipped with ab­sorb­ing ma­te­ri­als, These com­prise graphite and higher Z al­loys that are em­bed­ded on sub-as­sem­blies re­in­forced with back-stiff­en­ers made of TZM. The cur­rent con­tri­bu­tion cov­ers three main mat­ters. First, it de­tails the TDIS de­sign and its key tech­ni­cal fea­tures. The sec­ond topic dis­cussed is the out­come of an ex­per­i­ment where a pro­to­type mod­ule was tested under high-en­ergy beam im­pacts at CERN’s Hi­Rad­Mat fa­cil­ity. To con­clude it is pre­sented the re­turn of ex­pe­ri­ence from the pre-se­ries con­struc­tion, val­i­da­tion and in­stal­la­tion in the LHC tun­nel.
