  We dis­cuss the cur­rent sta­tus and plans for de­vel­op­ing the NSLS-II in­jec­tor. The lat­ter con­sists of a 200 MeV linac, a 3-GeV booster, trans­port lines and the stor­age ring in­jec­tion straight sec­tion. The sys­tem de­sign and in­stal­la­tion are com­plete. Last year we con­cluded 200-MeV linac com­mis­sion­ing and are plan­ning to com­mis­sion the 3 GeV booster dur­ing sum­mer of 2013.

  The booster syn­chro­tron of the NSLS-II light source at Brookhaven Na­tional Lab­o­ra­tory (BNL) pro­vides elec­tron beam ac­cel­er­a­tion from 200 MeV up to 3 GeV in 300 ms. This im­poses strict con­di­tions on both ac­cu­racy of con­trol and syn­chro­niza­tion of ramp­ing Power Sup­plies (PS). Hard­ware part of PS con­trols are based on elec­tron­ics spe­cially de­vel­oped at BNL and in­cludes Power Sup­ply Con­trollers (PSC) and Power Sup­ply In­ter­faces (PSI). The for­mer rep­re­sents dig­i­tal part of hard­ware and im­ple­ments low-level logic (gen­er­at­ing ramp func­tions, sim­ple data ver­i­fi­ca­tion and data ac­qui­si­tion), com­mu­ni­ca­tion with con­trol sys­tem soft­ware and PSI. The lat­ter is an ana­logue part of en­tire sys­tem and it per­forms gen­er­a­tion and ac­qui­si­tion ana­logue and dig­i­tal sig­nals by a set of on-board DACs, ADCs and dig­i­tal in­puts/out­puts. The PSC and the PSI are con­nected by dig­i­tal fibre optic link for elec­tri­cal de­cou­pling. This paper de­scribes soft­ware for the booster syn­chro­tron PSs con­trol which is based on EPICS and in­cludes a spe­cially de­signed elec­tron­ics con­fig­u­ra­tion, a set of pro­grams to man­age ramp func­tions and to con­trol dif­fer­ent types of power sup­plies, both pulsed and ramp­ing.

  The NSLS-II is a state of the art 3 GeV syn­chro­tron light source under con­struc­tion at Brookhaven Na­tional Lab­o­ra­tory. Since 2012, the in­jec­tor sys­tem grad­u­ally moves to the com­mis­sion­ing stage. It oc­curs after group peo­ple ef­forts on op­tics de­sign, equip­ment spec­i­fi­ca­tions, con­struc­tion and tests, as­sem­bly, in­stal­la­tion and align­ment. It is very im­por­tant and ex­cit­ing. To make the com­mis­sion­ing smooth and ef­fi­cient, an im­por­tant ef­fort was put on the sub-sys­tem in­te­gra­tion test to make sure the de­vice func­tion along with util­ity, tim­ing sys­tem and con­trol sys­tem, to cal­i­brate di­ag­nos­tics sys­tem and to debug high level ap­pli­ca­tion with sim­u­lated beam sig­nals and re­quired hard­ware. In this paper, we re­port our in­te­gra­tion test ex­pe­ri­ence and re­lated con­trol sys­tem soft­ware de­vel­op­ment.
