  ILSF booster syn­chro­tron is a full en­ergy 3GeV in­jec­tor with the cir­cum­fer­ence of 192m will be housed in a sep­a­rate tun­nel from stor­age ring. In order to keep low the emit­tance, a the­o­ret­i­cal min­i­mum emit­tance lat­tice in which the dipoles and quadrupoles have sex­tu­pole com­po­nent has been con­sid­ered for the booster. In this paper, the lat­tice con­cept and main fea­tures of the booster will be re­ported. The vari­a­tion of emit­tance and beam size dur­ing booster ramp­ing is also in­ves­ti­gated. Fi­nally the ef­fect of ex­isted eddy cur­rent on the chro­matic­ity and dy­namic aper­ture will be pre­sented.

  We have stud­ied ef­fects of dif­fer­ent in­ser­tion de­vices(IDs) in the high filed ILSF stor­age ring. Ra­di­a­tion from the IDs leads to change emit­tance and en­ergy spread of the ring and mag­netic field of them re­sults to beta-beat­ing, tune shift and shrink of dy­namic aper­ture. This paper de­scribes ef­fects of the IDs on beam pa­ra­me­ters of the high field lat­tice struc­ture of ILSF stor­age ring and pro­poses the com­pen­sa­tion method of these ef­fects.

  In the high in­ten­sity stor­age rings, there are many sources of er­rors which lead to closed orbit dis­tor­tion (COD). To study ef­fect of er­rors on closed orbit and to find op­ti­mum arrange­ment of beam po­si­tion mon­i­tors (BPMs) and strength of cor­rec­tor mag­nets, dif­fer­ent types of ex­pected mis­align­ments and field er­rors were im­posed ran­domly in the high field lat­tice of ILSF stor­age ring. This paper gives the re­sults of closed orbit cor­rec­tion in the ILSF ring and stip­u­lates the strength of cor­rec­tors.

  The Iran­ian Light Source Fa­cil­ity (ILSF) pro­ject is a first large scale ac­cel­er­a­tor fa­cil­ity which is cur­rently under plan­ning in Iran. The cir­cum­fer­ence of the stor­age ring is 297.6 m with the en­ergy of 3 GeV. The fa­cil­ity will be built on a land of 100 hectares area in the city of Qazvin, lo­cated 150 km West of Tehran. The city is sur­rounded by many uni­ver­si­ties, re­search cen­ters and in­dus­trial com­pa­nies. The de­sign and con­struc­tion of pro­to­type items such as radio fre­quency solid state am­pli­fier, di­pole mag­nets, highly sta­ble mag­net power sup­plies and gird­ers have al­ready begun. A low field H-type di­pole mag­net with the cen­tral field of 0.5T at the gap of 34mm and length of 500mm was built and tested in site. Also a pro­to­type stor­age ring quadru­pole with a 18 T/m gra­di­ent and 233 iron length is in now in fab­ri­ca­tion process. Site se­lec­tion stud­ies, in­clud­ing ge­ot­ech­ni­cal and seis­mo­log­i­cal mea­sure­ments are being per­formed. Con­cep­tual De­sign Re­port, CDR, as the first mile­stone of the pro­ject has been pub­lished on Oc­to­ber 2012.

  There are two trans­fer lines (T-lines) which link the Iran­ian Light Source Fa­cil­ity (ILSF) ac­cel­er­a­tor com­plex to gather. Sev­eral cri­te­rias have been con­sid­ered in de­sign stage of the T-lines. This paper gives lin­ear op­ti­miza­tion re­sults of the de­signed T-lines based on the first lay­out of the ILSF.

  The in­jec­tion sys­tem into a stor­age ring of a syn­chro­tron ra­di­a­tion fa­cil­ity sig­nif­i­cantly af­fects qual­ity of the elec­tron beam and the ra­di­ated x-ray. The ex­tracted 3 GeV elec­tron beam from the booster syn­chro­tron of the ILSF is trans­ferred via the BTS trans­fer line and in­jected into the ILSF stor­age ring based on high field lat­tice struc­ture. This paper de­scribes the in­jec­tion pro­ce­dure into the ILSF stor­age ring and gives the elec­tron track­ing re­sults of the in­jected beam.
