We present an approach for compensating adverse effects of the detector solenoid in the SuperB Interaction Region (IR). We place compensating solenoids around the IR quadrupole magnets to reduce the magnetic fields nearly to zero. This allows more operational headroom for superconducting IR magnets and avoids saturation of ferric IR magnets. We place stronger compensating solenoids between IR m...

 This article proposes a new dual-sided permanent magnet (DSPM) machine with flux-concentrated U-shaped magnets (PMs) in stator, and consequent-pole PMs rotor, respectively. The proposed DSPM can perform bidirectional field modulation effect (BFME) to enhance the effective harmonics, hence improving torque capability. A magneto-motive force-permeance based model is employed reveal produc...

Each stage of an accelerator system has a limited dynamic range and therefore a chain of stages is required to reach high energy. A combination of septa and kicker magnets is frequently used to inject and extract beam from each stage. The kicker magnets typically produce rectangular field pulses with fast riseand/or fall-times, however, the field strength is relatively low. To compensate for th...

NIIEFA have developed and began manufacturing a cyclotron project for the acceleration of multiple-charged ions to energies regulated in range 7.5-15 MeV/nucl. The electromagnet is H-shaped. system consists two dees, located "valleys". Acceleration performed at even harmonics. Ions are injected from external sources through axial channel. classical deflector magnetic channels ...

The theory of spin superradiance, developed earlier for nuclear magnets, is generalized to a wider class of spin systems, such as granular magnets and molecular magnets. The latter may possess strong single-site magnetocrystalline anisotropy, whose role in nonlinear spin dynamics is analysed. Transient as well as pulsing superradiant regimes are described. These coherent regimes may be employed...

Among the few foreign bodies swallowed, multiple magnets are very rare. Ingestion of Multiple Magnets may lead to a number of dire complications. The present case report is about the ingestion of multiple singing magnets by 4-year-old child leading to intestinal segmental necrosis and perforations.

This paper proposes the design of a weighted-rotor energy harvester (WREH) in which the oscillation is caused by the periodic change of the tangential component of gravity, to harvest kinetic energy from a rotating wheel. When a WREH is designed with a suitable characteristic length, the rotor’s natural frequency changes according to the wheel rotation speed and the rotor oscillates at a wide a...
