We pre­sent the cur­rent sta­tus of the beam track­ing sim­u­la­tions of the Com­pact Lin­ear Col­lid­er (CLIC) from the exit of the damp­ing ring to the in­ter­ac­tion point, in­clud­ing the ring to main linac (RTML) sec­tion, main linac, beam de­liv­ery sys­tem (BDS) and beam-beam in­ter­ac­tions. This model in­tro­duces re­al­is­tic align­ment sur­vey er­rors, dy­nam­ic im­per­fec­tions and also the pos­si­bil­i­ty to study col­lec­tive ef­fects in the main linac and the BDS. Spe­cial em­pha­sis is put on low emit­tance trans­port and beam sta­bi­liza­tion stud­ies, ap­ply­ing beam based align­ment meth­ods and feed­back sys­tems. The aim is to per­form re­al­is­tic in­te­grat­ed sim­u­la­tions to ob­tain re­li­able lu­mi­nos­i­ty pre­dic­tions.

Over the last months the gen­er­al lay­out of the CLIC main beam RTML has sta­bi­lized and most im­por­tant lat­tices are ex­ist­ing. This al­lowed us to per­form de­tailed stud­ies of tol­er­ances on mag­net­ic stray fields and on mag­net mis­align­ment. Ad­di­tion­al­ly, beam lines could be im­proved in terms of per­for­mance and flex­i­bil­i­ty. We dis­cuss the over­all lay­out as will be de­scribed in the CLIC con­cep­tu­al de­sign re­port, high­light the im­prove­ments which have been made and show re­sults of tol­er­ance stud­ies.

The Com­pact Lin­ear Col­lid­er (CLIC) ac­cel­er­a­tor has strong pre­ci­sion re­quire­ments on the po­si­tion of the beam. The beam po­si­tion will be sen­si­tive to ex­ter­nal dy­nam­ic mag­net­ic fields (stray fields) in the nan­otes­la regime. The im­pact of these fields on the CLIC main beam has been stud­ied by per­form­ing sim­u­la­tions on the lat­tices and tol­er­ances have been de­ter­mined. Sev­er­al mit­i­ga­tion tech­niques will be dis­cussed.

The CLIC BDS tun­ing, align­ment and feed­backs stud­ies have been typ­i­cal­ly per­formed in­de­pen­dent­ly and only over par­tic­u­lar sec­tions of the BDS. An ef­fort is being put to in­te­grate all these pro­ce­dures to re­al­is­ti­cal­ly eval­u­ate the lu­mi­nos­i­ty per­for­mance.
