  The Na­tional Syn­chro­tron Light Source II is a third gen­er­a­tion light source under con­struc­tion at Brookhaven Na­tional Lab­o­ra­tory. The pro­ject in­cludes a highly op­ti­mized 3 GeV elec­tron stor­age ring, linac pre-in­jec­tor and full-en­ergy in­jec­tor-syn­chro­tron. Bud­ker In­sti­tute of Nu­clear Physics build booster for NSLS-II. The booster should ac­cel­er­ate the elec­tron beam con­tin­u­ously and re­li­ably from a min­i­mum 170 MeV in­jec­tion en­ergy to a max­i­mum en­ergy of 3.15 GeV and av­er­age beam cur­rent of 20 mA. The booster shall be ca­pa­ble of multi-bunch and sin­gle bunch op­er­a­tion. Pre-comis­sion­ing test re­sults of booster com­po­nents and sys­tem are re­viewed.

  For the pur­pose of re­al­iza­tion of sin­gle-turn in­jec­tion and ex­trac­tion from the NSLS-II booster syn­chro­tron, BINP mem­bers cre­ated nanosec­ond non-vac­uum fer­rite kick­ers with fronts of pulsed mag­netic field of ~ 200 ns, flat-top du­ra­tion of 300 nsec and its in­sta­bil­ity of 0.2/1% at most. This paper de­scribes the de­sign of unique kicker mag­nets with ce­ramic vac­uum cham­bers with de­posited lon­gi­tu­di­nal strips of ti­ta­nium ni­tride (TiN) in­side. The paper also pre­sents the re­sults of bench tests of the kick­ers: os­cil­lo­grams of cur­rent pulse in bus bars, the shape of the pulsed mag­netic field, and trans­verse dis­tri­b­u­tion of the lon­gi­tu­di­nal field in­te­gral in the kicker aper­ture.

  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.

  Fo­cus­ing and de­fo­cus­ing dipoles mag­nets of NSLS-II 3 GeV booster are de­signed, man­u­fac­tured and mea­sured in BINP, Rus­sia. The mag­nets should pro­vide the booster op­er­a­tion at en­ergy from 170 MeV to 3.15 GeV with a 2 Hz fre­quency. Be­cause of booster com­pact­ness the dipoles have quadru­pole and sex­tu­pole com­po­nents and should cre­ate high qual­ity of field of ± 2·10-4 in re­gion of ± 2 cm. In this paper the de­sign and re­sults of 2D and 3D sim­u­la­tion are pre­sented.

To mea­sure mul­ti­pole field com­po­nents one need to know ac­cu­rate po­si­tion of the probes in 3D co­or­di­nates. This re­port con­sid­ers de­scrip­tion of the mag­netic mea­sure­ment stand and achived ac­cu­racy for DC case.
