  CERN’s ac­cel­er­a­tor com­plex of­fers di­verse tar­get sys­tems for a range of sci­en­tific pur­suits, in­clud­ing vary­ing beam en­er­gies, in­ten­si­ties, pulse lengths, and ob­jec­tives. Fu­ture high-in­ten­sity fixed tar­get ex­per­i­ments aim to ad­vance this field fur­ther. This con­tri­bu­tion high­lights up­graded op­er­a­tional tar­get sys­tems, en­hanc­ing CERN’s physics en­deav­ours. One ex­am­ple is the third-gen­er­a­tion nTOF spal­la­tion neu­tron tar­get, using a ni­tro­gen-cooled pure lead sys­tem im­pacted by a 20 GeV/c pro­ton beam. An­other fo­cuses on re­cent an­tipro­ton pro­duc­tion tar­get up­grades, with a high-in­ten­sity 26 GeV/c beam col­lid­ing with a nar­row-air-cooled irid­ium tar­get. Look­ing ahead, new high-power tar­get sys­tems are planned. One aims to dis­cover hid­den par­ti­cles using a 350-kW high-Z pro­duc­tion tar­get, while an­other en­hances kaon physics through a 100 kW low-Z tar­get. This ar­ti­cle pro­vides an overview of cur­rent tar­get sys­tems at CERN, de­tail­ing beam-in­ter­cept­ing de­vices and en­gi­neer­ing as­pects. It also pre­views up­com­ing fa­cil­i­ties that could soon be im­ple­mented at CERN.
