Large Spherical Magnetic Shield Room

Abstract

A unique large magnetic shield room of the spherical type has been constructed on the new campus of the Institute of Space and Astronautical Science. A spherical shield room is theoretically of good design to produce a nice uniform field inside it. The purpose of the magnetic shield room is to test the magnetic characteristics of spacecraft, satellite, sounding rocket payload and their subsystems, the calibration of magnetometer and others. The present shield room is also used as an electric shield room. Therefore, it is quite useful to check the electro-magnetic interference of payload system and to calibrate the high sensitive electronic circuit. The present paper describes the design and the shielding characteristic of the room. The authors wish that the shielding room can be used effectively by many investigators in the space science field and others. It is the authors desire that the shielding room will be utilized effectively by numerous investigations, not only in the space science field but also that of other fields of research. © 1985, Society of Geomagnetism and Earth, Planetary and Space Sciences.
