In the dynamic nuclear polarization process, microwave irradiation facilitates exchange of polarization from a radical's unpaired electron to nuclear spins at cryogenic temperatures, increasing polarization by >10,000. Doping samples with Gd(3+) ions further increases the achievable solid-state polarization. However, on dissolution, paramagnetic lanthanide metals can be potent relaxation agents...

The aim of this paper is to focus on the effect of cryogenic treatment on the microstructure, mechanical and wear properties of Al 6061 and Al 8011.  The first objective was to understand the degree to which hardness of these aluminium grades have been enhanced by giving  cryogenic on the specimens. The second objective is to check the wear resistance property of these two aluminium specimens i...

We explore the nanoscale colloidal self-assembly and self-alignment in liquid crystals. We use model particles with controlled shapes and sizes, including quantum dots and rods and metal nanoparticles in the form of spheres, rods, and polygonal platelets. To study these composites on the scales ranging from nanometers to millimeters and to motivate their use in metamaterial fabrication, we util...

Capacitive devices are customarily used as probes to measure the level of noble liquids in detectors operated for neutrino studies and dark matter searches. In this work we describe the use of a high-temperature superconducting material as an alternative to control the level of a cryogenic noble liquid. Lab measurements indicate that the superconductor shows a linear behaviour, a high degree of...

The target system for a muon collider/neutrino factory requires the conjunction of an intense proton beam, a highZ liquid target and a high-field solenoid magnet. We describe the design parameters for a pulsed solenoid, including the magnet cryogenic system and power supply, that can generate transient fields of greater than 10T with a flattops on the order of 1 second. It is envisioned to loca...
