A design for a radio frequency (RF) neutron spin flipper obtained from magneto-static and neutron spin transport simulations is presented. The RF flipper constructed from this design provides a flipping probability of 0.999 or better for a beam size

An important consideration when designing a magnetostatic cavities for various applications is to maximize the ratio of the volume of field homogeneity to overall size of the solenoid. We report a design of a magnetically shielded solenoid that signi

Polarized 3He neutron spin filters can operate over a wide neutron energy range and provide a large angular acceptance. A compact 3He neutron spin filter system has been developed for the Multi-Axis Crystal Spectrometer at the National Institute of S

The weakness of electron-electron correlations in the itinerant antiferromagnet Cr doped with V has long been considered the reason that neither new collective electronic states or even non Fermi liquid behaviour are observed when antiferromagnetism
