Conveyance Test by Oscillation and Rotation to a Permanent Magnet Repulsive-Type Conveyor

Various applications of a single-axis controlled repulsive-type magnetic bearing have been proposed earlier. However, most conventional systems are equipped with a set of passive magnetic bearings and an active magnetic bearing. In this paper a new repulsive-type conveyor system with many passive magnetic bearing pairs is proposed. This system enables an easy rotation with negligible friction and soft conveyance by radial stiffness between the rotor and the stator permanent magnets. This paper also reports a conveyance test using ellipse motion of each shaft

Analysis and results of the Sn-104 Coulomb excitation experiment

The analysis of the Coulomb excitation experiment conducted on Sn-104 required a strict selection of the data in order to reduce the large background present in the gamma-ray energy spectra and identify the gamma-ray peak corresponding to the Coulomb excitation events. As a result the B(E2; 0(+) -> 2(+)) value could be extracted, which established the downward trend towards Sn-100 and therefore the robustness of the N=Z=50 core against quadrupole excitations
