	Status of the project of Nuclotron-based Ion Collider fAcility NICA/MPD (MultiPurpose Detector) under development at JINR (Dubna) is presented. The general goals of the project are providing of colliding beams for experimental studies of both hot and dense strongly interacting baryonic matter and search for the mixed phase and critical endpoint. Spin physics experimental studies in collisions of polarized protons (deuterons) are planned as the second stage of the project. The first program requires providing of heavy ion collisions in the energy range of squrt(s) = 4-11 GeV at average luminosity of L = 1·1027 cm-2 s-1 for Au79+. The polarized beams mode is proposed to be used in energy range of squart(s) = 12-27 GeV (protons) at luminosity of L = 1·1030 cm-2 s-1. The key issue of the project is application of both stochastic and electron cooling methods at the NICA collider. The latter will be used in the NICA Booster for preliminary formation of the ion beam. The report contains description of the facility scheme and characteristics in heavy ion operation mode, the discussion of luminosity life time limitations, status and plans of the project development.

	The 2 MeV electron cooling system for COSY-Juelich was proposed to further boost the luminosity even in presence of strong heating effects of high-density internal targets. The project is funded since mid 2009. The design and construction of the cooler is accomplished in cooperation with the Budker Institute of Nuclear Physics in Novosibirsk, Russia. The 2 MeV cooler is also well suited in the start up phase of the High Energy Storage Ring (HESR) at FAIR in Darmstadt. It can be used for beam cooling at injection energy and is intended to test new features of the high energy electron cooler for HESR. The infrastructure necessary for the operation of the cooler in the COSY ring (radiation shielding, cabling, water cooling etc.) is established. The electron beam commissioning at BINP Novosibirsk is scheduled to start at May of 2011. First results are reported. Final commissioning at COSY-Juelich is planned for the end of 2011.

	At S-LSR in ICR, Kyoto University, approaches to multi-dimensional laser cooling of Mg ions with the use of synchro-betatron coupling has been applied in addition to the realization of one dimensional ordering of 7 MeV proton beam with application of an electron beam cooling. In the present paper, recent results of transverse cooling of bunched beam will be presented together with an aproach to provide a short bunch 7 MeV proton beam with a high peak current to make bio-medical irradiation of biological cells.

TUPS05	Simulation of High-Energy Electron Cooling at COSY with BETACOOL Program	electron, target, simulation, luminosity	95
	L. J. Mao, J. Dietrich FZJ, Jülich
	A 2 MeV electron cooling device will be installed at COSY in order to boost the luminosity of pellet target experiments. The magnetized electron cooling technique is used to compensate the energy loss and emittance growth for future COSY pellet target experiments. In this article, a numerical simulation of cooling process is performed with BETACOOL code. The cooling time is calculated for variant cooler setting parameters. The intrabeam scattering (IBS) and target effect are essential for prediction of equilibrium beam parameters. The influence of the pellet target on the beam parameters is demonstrated.
