Estimation of the average vaccum in the Nuclotron ring
measuring circulating deutron beam lifetime at Е=5 MeV/u
corresponds to the vacuum pressure not worse than 4*10-10 Тоrr.

Nuclotron-M Results
First 6 turns (about 50 s), deutron beam after orbit correction. Blue injected beam, Red - signal from pick-up.
Circulating beam signals during 1150 ms. Small increasing of the signal
amplitude is connected to beam de-bunching

Nuclotron-NICA
Heavy Ion Source KRION-6T
Assembling of electron/ion optics system:
view from the “ion extraction” side.
Superconducting test coil (L=19 cm, 32
layers of SC wire) : preparation for
testing in a liquid helium.
Magnetic field (T) versus current (A) for SC
solenoids; experimental and expected data.
1) 26 layers (green line, 21 Jan.’11) – 7.41T at
I_crit.=131 A (experimental data);
2) 32 layers (top green line, 25 Apr.’11) – 7.81T at
I_crit=114 A (experimental data);
3) red line: critical current for SC wire according it’s
manufacturer data;
4) blue line: expected for Krion-6T ESIS – 22 layers,
L=120 cm, B=6 T at I_working=118 A . Should be
ready in September 2011.

Nuclotron-NICA
Moreover:
- dedicated test bench for injection system (inflector plates)
into Booster is in operation;
- dedicated prototype of HV platform (PS 225kV/3A) is under assembly;
- new system of the whole complex synchronization is under design
and construction;
- new thermometry and quench detection system for Nuclotron is in progress;
-…
PLANS:
Next run at Nuclotron with prolonged period (1,5-2 months) is planned
for November-December 2011 and beam will be delivered mainly for physicists.
