	Electron String Ion Source (ESIS) "Krion-2" (JINR) is the first and now only ion source of such type in the world. ESIS is a sophisticated modification of Electron Beam Ion Source (EBIS) working in a reflex mode of operation under very specific conditions. The main results, which were achieved during recent years are: Au⁵⁴⁺ ion beams with intensity 5x10⁷ particle per pulse were first produced, ion-ion cooling technology was demonstrated to prove its efficiency for a thermal ion loss reduction and Krion-2 was used for production and injection of Xe⁴²⁺ ion beam into LINAC injector of JINR synchrotron Nuclotron, where the beam was first accelerated to relativistic energy in March 2010 [1-3]. At the present time an essential progress was achieved in construction of the new 6 Tesla ESIS, which is expected to be the full scale prototype of a highly charged ion source for NICA - the new JINR accelerator complex. It is foreseen in the NICA project that new ESIS will provide Au³²⁺ beams with ion yield about 2x10⁹ ppp. However, a project parameters of new Krion-6T ion source allow to expect production of even more highly charged states of heavy elements, up to Au⁶⁹⁺ in terms of gold. In this case new Krion-6T ESIS is planned to be used on operating JINR "Nuclotron" facility in near future for experiments with an extracted accelerated gold ion beams on a fixed target. [1] D.E.

	Solenoids have important role in focusing the beam in drift tube of charge particle accelerators. In order to optimize the beam current in ES-200, an electrostatic proton accelerator at Shahid Beheshti University, design and simulation of a suitable solenoid has been performed. Using CST Studio package, simulation results has been validated in comparison with theoretical formula. According to the results we optimized the design using CST to have minimum beam current on drift tube.
