Cryo-Free 7.0T Actively-Shielded ICR Spectromet Magnet

描述(由申请人提供)： 用于离子回旋共振傅里叶变换质谱仪(ICR-FTMS)的无制冷剂、主动屏蔽的7.0T高分辨率超导磁体的开发将显著降低系统运行成本，提高操作员的安全性，并简化操作和维护。生物科学家和基因研究人员越来越依赖ICR-FTMS。拟议的FTMS主动屏蔽磁体系统将具有许多技术优势：超高分辨率、低系统运行成本(不需要重新填充制冷剂即可操作系统)、用户友好性(使用闭合循环制冷，CCR，光谱仪的磁体部分几乎无需维护)、紧凑的尺寸(由于主动屏蔽，系统可以适合小型实验室，而且低温恒温器将更小，因为不需要制冷剂存储容量)、灵活性和移动性(不需要制冷剂意味着制冷剂访问和可用性的问题将不再构成选址限制)。

DESCRIPTION (provided by applicant): The development of a cryogen-free, actively-shielded 7.0 T high resolution superconducting magnet for Ion Cyclotron Resonance Fourier Transform Mass Spectrometry (ICR-FTMS) will significantly reduce system operating costs, improve operator safety, and simplify operation and maintenance. Bio-scientists and genetic researchers rely more and more on ICR-FTMS. The proposed FTMS actively-shielded magnet system will have many technological merits: ultra high resolution, low system operating costs (no cryogen refilling will be required to operate the system), user-friendliness (using closed cycle refrigeration, CCR, the magnet portion of the spectrometer becomes almost maintenance free), compact size (due to the active shielding, the system can fit into a small laboratory, and the cryostat will be much smaller since no cryogen storage volume is necessary), flexibility and mobility (no cryogen requirement means problems with cryogen access and availability will no longer pose siting limitations).
