Title:
BIOMAGNETISM MEASUREMENT DEVICE
Document Type and Number:
Japanese Patent JP2016221184
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a biomagnetism measurement device that realizes the reuse of helium and the rotation of a magnetic sensor and reduces external magnetic fields that enter a magnetic shield room.SOLUTION: A biomagnetism measurement device comprises: a magnetic shield room; a cryogenic refrigerator installed outside the magnetic shield room; a cryostat installed inside the magnetic shield room; a transfer tube that penetrates the magnetic shield room and forms a flow passage of helium between the cryogenic refrigerator and the cryostat; and a magnetic sensor housed in the cryostat and cooled by the helium. The cryostat is configured rotatably by using the transfer tube as a rotating axis.SELECTED DRAWING: Figure 3
