  Bud­ker In­sti­tute has de­signed and de­liv­ered Booster for NSLSII pro­ject in­clud­ing vac­uum sys­tem, mag­net sys­tem, di­ag­nos­tics and power sup­plies. Di­pole power sup­plies were di­rectly de­liv­ered to BNL by sub-con­trac­tor (Dan­fysik, Den­mark). To test di­pole mag­nets on fac­tory side, at BINP, it was de­cided to de­sign and con­struct a high cur­rent ramp­ing mode power sup­ply. The de­signed power sup­ply can op­er­ate with the re­ac­tive out­put power up to 150kVA and out­put cur­rent up to 900A at 2Hz ramp­ing mode. The ab­solute ac­cu­racy achieved is bet­ter than 100ppm for the in­jec­tion and ex­trac­tion flats and bet­ter than 500ppm for the ramps.

  Power sys­tem for quadru­pole mag­nets of NSLS-II 3 GeV booster is de­signed, man­u­fac­tured and tested in BINP, Rus­sia. The power sys­tem con­sists of 2 parts. The first part is a charg­ing source with a ca­pac­i­tance bank at out­put. And the sec­ond part con­sists of 3 cur­rent sources pow­ered by a ca­pac­i­tance bank. The charg­ing source out­put volt­age is up to 180 V, peak power is 40 kW and av­er­age power is 20 kW. Ca­pac­i­tance bank has a 120 kVA stor­age en­ergy. The sec­ond part con­tains 3 in­de­pen­dent cur­rent sources with up to 180 A out­put cur­rent each. This re­port con­sid­ers the de­tails of cur­rent sources de­sign, their pa­ra­me­ters and re­sults of in­spec­tion test in BINP. Fi­nally, the first re­sults of in­jec­tion and ex­trac­tion sec­tion com­mis­sion­ing at BNL site are re­ported.
