    • The invention provides methods of charging superconducting materials and, in particular, methods of charging high-temperature superconducting materials. The methods generally involve cooling a superconducting material to a temperature below its critical temperature. Then, an external magnetic field is applied to charge the material at a nearly constant temperature. The external magnetic field first drives the superconducting material to a critical state and then penetrates into the material. When in the critical state, the superconducting material loses all the pinning ability and therefore is in the flux-flow regime. In some embodiments, a first magnetic field may be used to drive the superconducting material to the critical state and then a second magnetic field may be used to penetrate the superconducting material. When the external field or combination of external fields are removed, the magnetic field that has penetrated into the material remains trapped. The charged superconducting material may be used as solenoidal magnets, dipole magnets, or other higher order multipole magnets in many applications.
    • 本发明提供了对超导材料进行充电的方法,特别是对高温超导材料进行充电的方法。 所述方法通常涉及将超导材料冷却至低于其临界温度的温度。 然后,施加外部磁场以在几乎恒定的温度下对材料充电。 外部磁场首先将超导材料驱动到临界状态,然后穿透材料。 当处于临界状态时,超导材料失去所有的钉扎能力,因此处于通量流动状态。 在一些实施例中,可以使用第一磁场来将超导材料驱动到临界状态,然后可以使用第二磁场来穿透超导材料。 当外场或外场的组合被去除时,已经渗透到材料中的磁场被捕获。 在许多应用中,带电的超导材料可以用作螺线管磁体,偶极磁体或其它高阶多极磁体。

    • A method, a system, and an article of manufacture are disclosed for cryogenic cooling of systems operating at cryogenic temperatures or higher. Applications of this disclosure are as varied as trucking of meat and vegetable to mine sweeping and MRI systems. A cooling network is formed by coupling blocks of Thermal Energy Storage (TES) modules together with optional thermal switches or valves and optionally with an active cooling component to maintain a cryogenic temperature in a cryostat. The TES modules are combinations of thermal conducting elements to conduct heat and solid storage elements to absorb heat. The cooling component may be one or more cryocoolers for steady state and transient heat transfer conditions and may be coupled with the TES modules via thermal shunt connections. The thermal switches or valves may be deployed within the thermal shunts to control the flow of heat between different TES modules and cooling components, thus reconfiguring the cooling network.
    • 公开了用于在低温或更高温度下操作的系统的低温冷却的方法,系统和制品。 本披露的应用与将肉类和蔬菜运送到扫雷和MRI系统不同。 冷却网络通过将热能存储(TES)模块与可选的热开关或阀连接并且任选地具有主动冷却组件以将低温恒温器中的低温维持在一起而形成。 TES模块是导热元件的组合,用于传导热量和固体储存元件以吸收热量。 冷却部件可以是用于稳定状态和瞬态传热条件的一个或多个低温冷却器,并且可以经由热分流连接与TES模块耦合。 热开关或阀可以部署在热分流器内,以控制不同TES模块和冷却组件之间的热流,从而重新配置冷却网络。
