  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.

  The new neu­tron spal­la­tion tar­get for the CERN neu­tron Time-Of-Flight (n_TOF) fa­cil­ity is based on a ni­tro­gen-cooled Pb core im­pacted by short high-in­ten­sity pro­ton beam pulses. An ex­ten­sive ma­te­r­ial char­ac­ter­i­za­tion cam­paign has been car­ried out to de­fine the con­sti­tu­tive be­hav­ior of lead and as­sess its re­sponse under pulsed pro­ton beam ir­ra­di­a­tion. The ac­tiv­i­ties car­ried out in­clude a beam ir­ra­di­a­tion test in the CERN Hi­Rad­Mat fa­cil­ity. The tests and in­spec­tions per­formed show a ro­bust be­hav­ior of the core ma­te­r­ial dur­ing op­er­a­tion and promi­nent sta­tic hard­en­ing re­cov­ery al­ready at room tem­per­a­ture.
