  Basic goal of the planned NICA fa­cil­i­ty at JINR is fo­cused on the study­ing of heavy ion col­li­sions over the en­er­gy range √s ~ 4…11 GeV/u. Ca­pa­bil­i­ties of the pro­posed scheme were care­ful­ly an­a­lyzed in this case and reach­ing of the de­sired av­er­age lu­mi­nos­i­ty, L = 1·1027 cm-2 s−1 for gold-gold col­li­sions at √s = 9 GeV/u, have been con­firmed. The other im­por­tant NICA re­search do­main is the ex­per­i­ments with po­lar­ized pro­ton beams at the high­est pos­si­ble en­er­gy, the high­est lu­mi­nos­i­ty and po­lar­iza­tion de­gree as well. The main aim is to pro­vide √s ~ 25 GeV and L ~ 1·1031 cm-2 s−1. The un­solved as­pects of the prob­lem are dis­cussed, pos­si­ble so­lu­tions are an­a­lyzed and nec­es­sary mod­i­fi­ca­tions of the NICA scheme are con­sid­ered as well.

  The Nu­clotron up­grade – the Nu­clotron-M pro­ject, which had been start­ed in 2007, in­volved the mod­ern­iza­tion of al­most all of the ac­cel­er­a­tor sys­tems, using beam time dur­ing seven runs de­vot­ed to test­ing newly in­stalled equip­ment. Fol­low­ing the pro­ject goals, in March 2010 Xe ions were ac­cel­er­at­ed to about 1.5 GeV/u. In De­cem­ber 2010, the sta­ble and safe op­er­a­tion of the mag­net­ic sys­tem was achieved with a main field of 2 T. The suc­cess­ful com­ple­tion of the pro­ject paves the way for fur­ther de­vel­op­ment of the Nu­clotron-based Ion Col­lid­er fA­cil­i­ty (NICA).
