  As the first step of a long-term pro­gramme aim­ing at an in­crease in the LHC lu­mi­nos­i­ty, CERN is build­ing a new 160 MeV H− lin­ear ac­cel­er­a­tor, Linac4, to re­place the age­ing 50 MeV Linac2 as in­jec­tor to the Pro­ton-Syn­chrotron Boost­er (PSB). Linac4 is an 86-m long nor­mal-con­duct­ing linac made of an H− source, a Radio Fre­quen­cy Quadrupole (RFQ), a chop­ping line and a se­quence of three ac­cel­er­at­ing struc­tures: a Drift-Tube Linac (DTL), a Cell-Cou­pled DTL (CCDTL) and a Pi-Mode Struc­ture (PIMS). The civil en­gi­neer­ing has been re­cent­ly com­plet­ed, and con­struc­tion of the main ac­cel­er­a­tor com­po­nents has start­ed with the sup­port of a net­work of in­ter­na­tion­al col­lab­o­ra­tions. The low-en­er­gy sec­tion up to 3 MeV in­clud­ing a 3-m long 352 MHz RFQ en­tire­ly built at CERN is in the final con­struc­tion phase and is being in­stalled on a ded­i­cat­ed test stand. The pre­sent sched­ule fore­sees beam com­mis­sion­ing of the ac­cel­er­a­tor in the new tun­nel in 2013/14; the mo­ment of con­nec­tion of the new linac to the CERN ac­cel­er­a­tor chain will de­pend on the LHC sched­ule for long shut-downs.

  The LHC In­jec­tors Up­grade (LIU) pro­ject has been launched at the end of 2010 to pre­pare the CERN ac­cel­er­a­tor com­plex for re­li­ably pro­vid­ing beam with the chal­leng­ing char­ac­ter­is­tics re­quired by the high lu­mi­nos­i­ty LHC until at least 2030. Based on the work al­ready start­ed on Linac4, PS Boost­er, PS and SPS, the LIU pro­ject co­or­di­nates stud­ies and im­ple­men­ta­tion, and in­ter­faces with the High Lu­mi­nos­i­ty LHC (HL-LHC) pro­ject which looks after the up­grade of the LHC it­self, ex­pect­ed by the end of the pre­sent decade. The an­tic­i­pat­ed beam char­ac­ter­is­tics are de­scribed, as well as the sta­tus of the stud­ies and the so­lu­tions en­vis­aged for im­prov­ing the in­jec­tor per­for­mances.

  CERN’s pro­ton in­jec­tor chain is un­der­go­ing a mas­sive con­sol­i­da­tion and up­grade pro­gram in order to de­liv­er beams meet­ing the needs of the LHC Lu­mi­nos­i­ty Up­grade. As an al­ter­na­tive to the up­grade of the ex­ist­ing Pro­ton Syn­chrotron Boost­er (PSB), the con­struc­tion of a Rapid Cy­cling Syn­chrotron (RCS) has been stud­ied. This ma­chine would re­place the PSB and de­liv­er beams to the LHC as well as to CERN’s rich fixed-tar­get physics pro­gram. This paper sum­ma­rizes the out­come of the fea­si­bil­i­ty study along with a ten­ta­tive RCS de­sign.
