Title: Innovations by James G. Pierce
Introduction
James G. Pierce is an accomplished inventor based in Columbus, OH (US). He has made significant contributions to the field of refrigeration systems, particularly in the context of superconducting magnet technology. With a total of 3 patents, his work showcases a blend of creativity and technical expertise.
Latest Patents
One of his latest patents focuses on the refrigeration of superconducting magnet systems. This innovative refrigeration system includes a dewar and a refrigerator/liquefier designed to meet the variable demands of a superconducting magnet within the dewar. The system is engineered to accommodate average loads over a defined duty cycle while being variably operable to meet specific demands. In the preferred embodiment, a first supply of fluid circulates through a 'condenser' element positioned in a dewar ullage to liquefy a separate supply of fluid in the dewar and to refrigerate a pulsed cryogenic load, such as a superconducting magnet. Additionally, a portion of the first supply of fluid may be diverted to refrigerate a second pulsed cryogenic load, such as magnet current leads permanently connected to the magnet. The dewar features a cold gas vapor storage chamber separate from the dewar ullage, ideally located within the inner core of a solenoid superconducting magnet for a compact and thermally efficient design. This system allows for responsive, independent adjustment of refrigeration to pulsed cryogenic loads.
