BACKGROUND The superconducting cyclotron is of great importance to treat cancer parts of the body. To reduce the operation costs, a superconducting magnet system for the 250 MeV proton cyclotron was designed to confirm the feasibility of the superconducting cyclotron. FINDINGS The superconducting magnet system consists of a pair of split coils, the cryostat and a pair of binary high temperatu...

Is there a difference in the level of job satisfaction among clinical nurses employed at magnet versus nonmagnet hospitals, and is it linked to nurse executive leadership? To answer these questions, 305 clinical nurses employed at magnet and nonmagnet hospitals rated their perceptions of job satisfaction while 16 leaders from the same hospitals were interviewed for their perception of their rol...

This study looked at the effect of an external magnet on the biodistribution of magnetoliposomes intravenously administrated in mice (8 mg iron/kg) with and without induced acute inflammation. Our results showed that due to enhanced vascular permeability, magnetoliposomes accumulated at the site of inflammation in the absence of an external magnetic field, but the amount of iron present increas...

Magnetic flux measurements of a toroidal magnet revealed a concave-shaped field distribution with a single minimum and a null field along the axis of the torus at the point where the field reversed. The non-linear magnetic field of the toroidal magnet perpendicular to the Ag2O-doped superconducting disc sample with trapped magnetic flux distorted the field line distribution. As a result, the in...

Tendencies in development of wind power industry including direct-drive small-scale wind power plants and generators have been analyzed. Synchronous generators with permanent magnet excitation for direct-drive wind power turbines are described. Primary magnetic field distribution and effect of armature reaction have been studied for design of a low-speed multipole permanent-magnet synchronous g...

It had been observed that the mechanical stability of some magnets had influences on the closed orbit in the storage ring. In this paper, a mechanical shaker in low vibration level was applied on the quadrupole magnet. The perturbation of the closed orbit was measured. The thermal induced distortion of magnet supporting structure was discussed. The motions of BPM and quadrupole magnet were meas...

The JHF 50-GeV main ring, very high-intensity proton synchrotron, for the JHF project has been designed.[1][2] The main ring consists of 96 bending magnets, 176 quadrupole magnets, 48 sextupole magnets and 176 steering magnets. The bending magnet is of a modified window frame type, whose maximum field is 1.9 T. Field gradient of the quadrupole magnet is 20 T/m in peak and the bore radius is 63 ...

In this paper a brushless permanent magnet motor is designed considering minimum thrust ripple and maximum thrust density (the ratio of the thrust to permanent magnet volumes). Particle Swarm Optimization (PSO) is used as optimization method. Finite element analysis (FEA) is carried out base on the optimized and conventional geometric dimensions of the motor. The results of the FEA deal to ...

SIS100 will be operated with high intensity heavy-ion and proton beams. In order to avoid coherent beam instabilities, the reduction of the overall ring impedance is of great importance. The extraction kicker system is one of the main contributors to the overall ring impedance. This paper focuses on the contribution of the external electrical network to the kicker impedance. Previous calculatio...

The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis...
