Six­Track is a sym­plec­tic 6D track­ing code rou­tinely used to sim­u­late sin­gle par­ti­cle tra­jec­to­ries in high en­ergy cir­cu­lar ma­chines like the LHC and RHIC. The paper pre­sents the de­vel­op­ments re­cently im­ple­mented and those fore­seen for ex­tend­ing the physics mod­els: exact Hamil­ton­ian, dif­fer­ent ions and charge states, RF mul­ti­poles, non-lin­ear fringe fields, Tay­lor maps, e-lenses, ion scat­ter­ing. More­over new func­tion­al­i­ties are also added like vari­able num­ber of tracked par­ti­cles, time de­pen­dent strengths, GPU com­pu­ta­tions with a refac­tor­ing of the core struc­ture. The de­vel­op­ments will ben­e­fit stud­ies on the LHC and SPS, for col­li­ma­tion ef­fi­ciency, ion op­er­a­tions, fail­ure sce­nar­ios and HL-LHC de­sign.

  The LHC In­jec­tors Up­grade (LIU) Pro­ject aims at up­grad­ing the sys­tems in the LHC in­jec­tion chain, to re­li­ably de­liver the beams re­quired by the High-Lu­mi­nos­ity LHC (HL-LHC). Es­sen­tial for the clean in­jec­tion into the LHC, the SPS scrap­ers are one of the im­por­tant sys­tems under re­vi­sion. In order to take into ac­count of the ef­fect of be­ta­tron and lon­gi­tu­di­nal beam dy­nam­ics on en­ergy de­po­si­tion pat­terns, and nu­clear and Coulomb scat­ter­ing in the ab­sorb­ing medium onto loss pat­terns, the Six­Track and Fluka codes have been cou­pled, prof­it­ing from the best of the re­fined phys­i­cal mod­els they re­spec­tively embed. The cou­pling en­vis­ages an ac­tive ex­change of tracked par­ti­cles be­tween the two codes at each turn, and an on-line aper­ture check in Six­Track, in order to es­ti­mate the local clean­ing in­ef­fi­ciency of the sys­tem. Knob-like, time-de­pen­dent strengths have been im­ple­mented in Six­Track, since the de­signed scraper sys­tem fore­sees the use of a mag­netic bump. The study is in­tended to as­sess the ro­bust­ness of the pro­posed scraper as well as its ef­fec­tive­ness with re­spect to the de­sired per­for­mance.
