1. A dual-helmet magnetoencephalography measuring apparatus comprising:
an internal container comprising a glass fiber-reinforced plastic and storing a liquid refrigerant;
an external container surrounding the internal container and including a first external helmet and a second external helmet spaced apart from each other;
a first sensor-mounted helmet surrounding the first external helmet between the external container and the internal container;
a second sensor-mounted helmet surrounding the second external helmet between the external container and the internal container;
a plurality of first SQUID sensor modules on the first sensor-mounted helmet, each comprising a first SQUID sensor and a first pick-up coil; and
a plurality of second SQUID sensor modules on the second sensor-mounted helmet, each comprising a second SQUID sensor and a second pick-up coil,
wherein a space between the external container and the internal container is in a vacuum state.
