	I.N. Meshkov JINR, Dubna, Moscow Region, Russia
	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 = 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 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.

	R.M. Kriske University of Minnesota, Minneapolis, Minnesota, USA
	Recently, at an ILC meeting in Tokyo, the Electron, Anti-Electron Beam strength was said to be about 7 milliamps, for the newest design of the planned International Linear Collider. This was about 1000 times the strength of Colliders in the last decade. This author would like to explore a different way of feeding Anti-Electrons and Electrons into a Collider that should increase the Potential Beam Strength by about 100 times. The question then is how to use Klystrons to maintain an enhanced Beam Strength and whether the larger number of Electrons and Anti-Electrons would cause too much damage to the Accelerator walls. This method should work for Protons and Anti-Protons as well.
