This proposal covers the development of a helium temperature (4 Kelvin) cryocooler. This cryocooler can be used for continuous cooling of superconducting devices that require these temperatures. These include Magnetic Resonance Imaging (MRI) superconducting magnet systems and Superconducting Quantum Interference Detector (SQUID) based magnetoencephalography (MEG) systems. The cryocooler will have no moving parts in the cryogenic section, so the usual lifetime limiting elements are eliminated. The cryocooler will be designed for operation by technicians with no special training in cryogenic techniques. Therefore, the development will enable the widespread use of superconducting instruments in medical environments.

这项建议包括开发氦温度(4开尔文) 冷冻机。该制冷机可用于冷冻机的连续冷却 需要这些温度的超导装置。这些措施包括 磁共振成像(MRI)超导磁体系统和 超导量子干涉探测器(SQUID) 脑磁图(MEG)系统。制冷机将不会移动 部件在低温部分，所以通常的寿命限制元件是 被淘汰了。制冷机的设计将由技术人员操作。 没有接受过深冷技术方面的特殊训练。因此， 发展将使超导仪器的广泛使用成为可能 在医疗环境中。
