  In the frame­work of the CERN Large Hadron Col­lider In­jec­tors Up­grade (LIU) Pro­ject, the Pro­ton Syn­chro­tron (PS) has been equipped with two new mov­able In­ter­nal Dumps (PSID), each of them ca­pa­ble of ab­sorb­ing par­ti­cle beams of an en­ergy of up to 100 kJ. These dumps re­place the old In­ter­nal Dumps, which have been op­er­ated in the ac­cel­er­a­tor com­plex since their in­stal­la­tion in 1975 until their de­com­mis­sion­ing and re­moval from the ma­chine dur­ing the sec­ond LHC Long Shut down (LS2). This con­tri­bu­tion will ad­dress the con­struc­tion and test­ing phases of the new PSIDs, in­clud­ing the as­sem­bly of the dump core, its ac­tu­a­tion sys­tem and the re­spec­tive shield­ing, me­chan­i­cal run­ning-in tests, metrol­ogy ad­just­ments, Ul­tra-High Vac­uum (UHV) and im­ped­ance ac­cep­tance tests. The de­scribed in­stal­la­tion work was com­pleted suc­cess­fully, and the new gen­er­a­tion Dumps are cur­rently op­er­a­tional in the PS ma­chine.

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.

  The Beam Dump Fa­cil­ity (BDF), cur­rently in the study phase, is a pro­posed gen­eral-pur­pose fixed tar­get fa­cil­ity at CERN. Ini­tially will host the Search for Hid­den Par­ti­cles (SHiP) ex­per­i­ment, in­tended to in­ves­ti­gate the ori­gin of dark mat­ter and other weakly in­ter­act­ing par­ti­cles. The BDF par­ti­cle pro­duc­tion tar­get is lo­cated at the core of the fa­cil­ity and is em­ployed to fully ab­sorb the high in­ten­sity (400 GeV/c) Super Pro­ton Syn­chro­tron (SPS) beam. To val­i­date the de­sign of the pro­duc­tion tar­get, a down­scaled pro­to­type was tested with the beam at CERN in 2018 in the North Area pri­mary area in a ded­i­cated test at 35 kW av­er­age beam power. This con­tri­bu­tion de­tails the BDF pro­to­type tar­get op­er­a­tion, fully re­mote re­moval in­ter­ven­tion, and fore­seen post-ir­ra­di­a­tion ex­am­i­na­tion plans.
