	In the recent years, Russian government and scientific society have been coming gradually to an understanding the way of development science in Russia. Government have accepted a program of building six mega-science projects, and one of them can be a new 4-th generation x-ray light source based on accelerator-recuperator. Multiturn energy recovery linacs (ERL) looks very promising for making modern synchrotron radiation sources, being less expensive and more flexible. At this time only one multiturn ERL exists. This Novosibirsk ERL operates with two orbits and two free electron lasers based on one linac now. The conception of Multiturn Accelerator-recuperator Radiation Source (MARS) was proposed in 1997 by G.N. Kulipanov, A.N. Skrinsky and N.A. Vinokurov. The use of the ERL with two separated accelerating structures allows to exclude main disadvantages of scheme with one linac, such as the pass of electron bunches with different energies through the same magnetic arcs. The feasibility study for such ERL-based high brightness x-ray source is presented.

FRBOR01	Progress in the Negative Ion Sources Development	ion, plasma, ion-source, cathode	213
	V.G. Dudnikov Muons, Inc, Batavia, USA
	Modern trends and recent progress in development of negative ion sources will be considered and analyzed. Surface Plasma Sources (SPS) rely on cesium-enhanced plasma surface reactions to produce negative ions are main sources delivering the negative ion beam for charge exchange injection in accelerators and fusion devices. After development of the SPS with cesiation the negative ion beam intensity has increased up to ~10⁴ times, from a record 3 mA to more than 40 A. Since the original conception of SPS with cesiation, many modifications and improvements have been made such that they constitute a mature and reliable technology today. The world-wide effort on the development and use of SPS with cesiation has increased to more than a thousand highly qualified scientists, engineers, technicians, workers, and administrators. The cost scale of advanced SPS has increased from ~ k to ~ M. SPS with cesiation have become "sources of life" and "working horses" for big installations such as SNS, LANSCE, BNL, FNAL, ISIS, KEK, JT 60 (Japanese tokamak), and the LHD (Large Helicon Device). Large development projects include the SPS for the Large Hadron Collider (LHC) and for the International Thermonuclear Experimental Reactor (ITER). The development and fabrication of injectors with cesiated SPS has become a billion dollar scale industry.

TUPPB045	The Field Cathodes with the Effect of Space Charge Modeling	space-charge, electron, cathode, vacuum	415
	M.A. Makarova, E.M. Vinogradova Saint-Petersburg State University, Saint-Petersburg, Russia
	This work is devoted to the question of the effect of space charge on the field electron emission. The electrostatic potential distributions for the diode emission systems are calculated. The diode systems, which can be readily constructed, is generally used for the characterization of field emission properties of novel materials. They have some effective applications in vacuum nano- and microelectronics. In this work the plane diode emission system and cylindrical diode emission system are investigated. The solutions of Poisson's equation for the electrostatic potential distribution are received for the boundary-value problems. The right side of Poisson's equation is assumed to be the piecewise constant function. The charge conservation law and the energy conservation law are used. One and two dimensional cases are investigated.
