An isocentric superconducting rotating-gantry for heavy-ion therapy is being developed [1]. This rotating gantry can transport heavy ions having 430 MeV/u to an isocenter with irradiation angles of over ±180°, and is further capable of performing fast raster-scanning irradiation [2]. A layout of the beam-transport line for the compact rotating-gantry is presented in Fig. 1. The rotating gantry ...

Distributed energy resources (DER) are in transition from the lab to the marketplace. The defining characteristic of DER is that they are active devices installed at the distribution system level, as opposed to the transmission level. While no specific size range has been defined, most distribution systems would have difficulty accommodating distributed generating resources larger than 10 MW/MV...

This paper presents a combinatorial standalone permanent magnet synchronous generator (PMSG) based variable speed wind turbine (VSWT) and small-size superconducting magnetic energy storage (SMES) system into the DC microgrid system. The principal purpose of SMES system is to preserve power balance by absorbing power during peak wind generation and to release it during low power generation. This...

In this paper an attempt has been made to control frequency deviations using Particle Swarm Optimization (PSO) in a two area system. and PSO technique has been compared with GA. This study also involve analysis of AGC with energy storage unit like super-conducting magnetic energy storage system. Parameters of super conducting magnetic energy storage unit (SMES) have been optimized using PSO to ...

We investigate the evolution of a superconducting string network with arbitrary, constant string current in the friction dominated regime. In the absence of an external magnetic field the network always reaches a scaling solution. However, for string current stronger than a critical value, it is different than the usual, horizon–scaling of the non-superconducting string case. In this case the f...

The superconductivity at 39 K discovered in MgB2 among simple binary chemical composition attracted much interest in its fabrication techniques and practical applications [1]. MgB2 superconductor exhibits many impressive properties such as highest critical temperature amongst intermetallic superconductors which means low cooling costs, impressive grain boundary transparency to the flow of curre...
