Title:
HIGHLY PRESSURE-RESISTANT COOLING CONTAINER FOR SENSOR AND UNDERGROUND PROBING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/208443
Kind Code:
A1
Abstract:
In the highly pressure-resistant cooling container for a sensor and the underground probing device according to the present invention, it possible to continue cooling a SQUID to a stable operating temperature over a long period of time within a high pressure exceeding 1.0 MPa. The present invention is provided with a pressure-resistant airtight container that is resistant to pressures of at least 1.0 MPa, a phase-transition-coolant thermal insulation device housed within the pressure-resistant airtight container, and a phase-transition-coolant releasing tube that is connected to the pressure-resistant airtight container and is resistant to pressures of at least 1.0 MPa.
