A compact pod for modular superconducting electronics

Abstract

The invention discloses a modular superconductivity electronic equipment pod compact in structure. The modular superconductivity electronic equipment pod is characterized in that the pod is composed of an upper end cover, a lower end cover, a shell and a pod-penetrating piece, and the pod-penetrating piece is fixed to the center of the upper end cover; three eccentric-circle pile plates are adopted in the pod to establish a modular stack structure and to provide support for a superconductivity sensor assembly and a measurement and control assembly under the precondition that a vacuum bleeder valve outside a Dewar cylinder body is prevented from being bumped, and therefore integrity of a Dewar and a stack assembly is achieved; the modular stack structure formed by the three eccentric-circle pile plates is in rigid connection with the Dewar cylinder body through lengthened bolts between the cylinder body and a plug, and the eccentric-circle pile plate structural components of the stack assembly are connected through threaded rods; an SQUID device and a selected direct-reading type SBC are placed in a low-temperature container Dewar formed by the Dewar cylinder body and the Dewar plug. The pod is easy to realize, low in cost and capable of guaranteeing maintainability, expandability and environmental suitability of superconductivity electronic equipment within limited space.
