  The pro­ject NICA is being con­structed in JINR, Dubna to pro­vide col­li­sions of heavy ion beams in the en­ergy range from 1 to 4.5 GeV/u at the lu­mi­nos­ity level of 1*1027 cm-2*s−1. One of the el­e­ments in the col­lider in­jec­tion chain is BUSTER – a cy­cling ac­cel­er­a­tor of ions 197Au32+. The in­jec­tion en­ergy of par­ti­cles is 6.2 MeV/u, ex­trac­tion en­ergy is 600 MeV/u. Two RF sta­tions are to pro­vide 10 kV of ac­cel­er­a­tion volt­age. Fre­quency range of op­er­a­tion of the sta­tions in the in­jec­tor chain is from 634 kHz to 2400 kHz. The pro­vi­sions are made for au­tonomous mode of op­er­a­tion of the sta­tions in the fre­quency range of 0.5 – 5.5 MHz at the same ac­cel­er­at­ing volt­age. Amor­phous metal rings of Russ­ian pro­duc­tion are used in the RF cav­i­ties. RF sta­tions are cre­ated in the Bud­ker In­sti­tute of Nu­clear Physics, SB RAS, Novosi­birsk. The sta­tions are tested in the op­er­a­tive mode and will be de­liv­ered to the cus­tomer in Oc­to­ber, 2014. Main de­sign fea­tures and pa­ra­me­ters of RF cav­ity, power gen­er­a­tor and con­trol sys­tem of the sta­tions are de­scribed in the paper.

The sta­bil­ity of the main field has great in­flu­ence on pre­ci­sion ex­per­i­ments on par­ti­cle physics which are per­formed on VEPP-4M fa­cil­ity cur­rently. A method of broad­band sta­bi­liza­tion of the VEPP-4M main field al­low­ing us to achieve field sta­bil­ity bet­ter than 0.5 ppm over DC - 50Hz fre­quency range is pre­sented. The method com­bines NMR sta­bi­liza­tion and feed­back loop using in­duc­tion sig­nal.

  A com­pact con­tin­u­ous-wave lin­ear ac­cel­er­a­tor for in­dus­trial ap­pli­ca­tions with an out­put elec­tron en­ergy of 1 MeV and de­sign av­er­age beam cur­rent of 25 mA is de­scribed. The re­sults of beam dy­nam­ics, ac­cel­er­at­ing struc­ture, and RF sys­tem sim­u­la­tion are pre­sented, ac­cel­er­a­tor con­struc­tion and first re­sults of its com­mis­sion­ing are de­scribed.

In this paper dy­nam­ics of processes in ac­cel­er­a­tor dri­ven sys­tem (ADS) is con­sid­ered. ADS re­ac­tor op­er­ates at sub­crit­i­cal level and the nec­es­sary neu­tron sup­ply comes from the in­ter­ac­tion of a charged par­ti­cles beam with a heavy atom nu­cleus (spal­la­tion re­ac­tion). Math­e­mat­i­cal model of dy­nam­ics of sub­crit­i­cal re­ac­tor con­trolled by lin­ear ac­cel­er­a­tor is pre­sented. Cal­cu­la­tion re­sults of tran­sient processes in the re­ac­tor core tak­ing into ac­count fuel feed­back. The re­ac­tor power level con­trol is car­ried out through the reg­u­la­tion of linac cur­rent im­pulses fre­quency.
