Beam slow extraction system at maximum energy(V. Volkov)
Works on design of new high voltage power supply for the electro-static septum in the LHEP
design bureau were completed in autumn 2008. Prototype of such system was constructed and
successfully tested up to 140 kV (existing septum power supply allows up to 110 kV only – it
corresponds to 2,3 GeV/n extracted beam).
Now all the elements of new power supply had been manufactured at LHEP workshops and
this system is assembled – 03 Jan 2010: tested up to 220 kV. We plan to install it in the slow
extraction sector in order to provide experiments on beam extraction at energy 4 GeV/n during
next Nuclotron run.

The PAC takes note of the report by the Chairman of the
Machine Advisory Committee (MAC) for the Nuclotron-M/NICA accelerator complex, Prof. B. Sharkov and recognizes the significant progress in the realization of the Nuclotron-M project. The PAC expresses its gratitude to the MAC Chairman, members and experts for fulfilling an extremely important role in the project realization. The PAC especially notes that the expertise performed by the MAC has confirmed the feasibility of the NICA project.

VI. Recommendations on the progress towards the MPD Conceptual Design Report
The PAC takes note of the report on the preparation of the MPD Conceptual Design Report, presented by VBLHEP Director V. Kekelidze. The PAC notes with interest the progress of work on the MPD conceptual design and supports the basic ideology of the construction of the detector which will be unique in acceptance and efficiency for the registration of charged hadrons in the energy field under the study. The PAC supports the strategy of stage-by-stage construction of this detector and notes the substantial progress in scrutinizing all the basic elements. The PAC recommends preparing a project of the first-stage realization of the multipurpose set-up MPD — the starting stage –– and presenting at the next meeting of the PAC.

VII. Recommendations on the progress towards the NICA White Paper
The PAC takes note of the report by BLTP Deputy Director A. Sorin on the ongoing preparation of the white paper for the NICA programme on the mixed phase and spin physics. The PAC notes the progress achieved in this direction and recommends continuation of the work to elaborate a competitive research programme in view of its complementarity with studies planned at CERN, RHIC, and FAIR.

IX. Recommendations on the first experience of JINR physicists in data taking in the LHC experiments
The PAC takes note of the reports on the first experience of JINR physicists in data taking in the ALICE, ATLAS and CMS experiments. The PAC congratulates these teams for having fulfilled their obligations in the construction of the detectors and the commissioning phase. The PAC highly appreciates the presentation of the first physics results which witness the overall good operation of the detectors. The PAC recognizes the LIT important contribution to the first data analysis phase.
18/II/2010 Egle Tomasi-Gustafsson 15
X. Recommendations for new projects (I)
The PAC suggests supporting JINR’s participation in the physics research programmes at the LHC on the basis of a five-year term. The PAC recommends approval of the projects “JINR’s participation in the physics research at the LHC. ATLAS, ALICE, CMS” for execution until the end of 2014.
The PAC recommends that sufficient resources be allocated for the participation of JINR in the data taking and analysis, in order to match the strong commitment deployed during the construction phase with a corresponding effort during the physics and analysis phase. The PAC looks forward to receiving regular reports on these activities at its future meetings.

X. Recommendations for new projects (II)
2. The PAC recommends approval of JINR’s participation in the project “STAR at RHIC” until the end of 2012. The PAC supports the participation in the beam energy scan and in the polarized proton-proton data programme which will provide world-class results and represent an important training ground for the NICA collider project.
(Results: Z-scaling, strangeness, critical point)
3. The PAC appreciated the ongoing activity at JINR and recommends approval of JINR’s participation in the project “PANDA. Experiments at FAIR” until the end of 2014, considering the time scale of the project.
(Magnet, DIRC and Muon mini-drift tubes)

We continue collaboration works with INR (Troitsk) on the development of the new high-intensity polarized deuteron source, and signed an addendum for work prolongation in 2009. We plan to complete TDR documentation in this year and start construction of some elements at INR.
Simulation, modeling and design of different elements of the future source are in active phase at LHEP.
Experimental hall for the future test bench with that source is prepared at LHEP building 203A, preparation electrical and water-cooling works were performed.
It is planned to purchase part of necessary vacuum equipment (TMN pumps) for the SPD realization in 2009 – done.
