With the increasing demand of accelerators for high-energy particles, it is necessary to develop ECRIS (electron cyclotron resonance ion source) with compact structure, small volume, and high energy. ECRIS, which generates highly charged particles, is an essential component of heavy ion accelerators and heavy ion therapy equipment. A new S-shaped hexapole structure was proposed in 2016, which...
MgB2 based superconducting planar undulators are of interest for future electron storage rings for synchrotron radiation by virtue of their higher temperature operation margin with higher stability. In this work, an undulator winding consisting of twelve small pancake coils wound with multifilamentary MgB2 strands was fabricated and tested in liquid and gaseous He, from 4.2 K – 20 K. The coil...
The U.S. Air Force has wide ranging needs for electrical energy storage systems. Superconducting magnetic energy storage (SMES) devices offer attractive and unique features including no theoretical limit to specific power, high cycling efficiencies and charge/discharge rates, and virtually no degradation with cycling. The mass specific energy density (MSED) of SMES systems however falls short...
In the practical application of high temperature (HTS) REBCO coated conductor (CC) tapes, such as epoxy-impregnated or no-insulation (NI) coils, they can experience radial and transversely applied stress due to the large Lorentz force, thermal stress induced by the difference in coefficient of thermal expansion (CTE) among constituent layers which can result in delamination damage and...
