Abstract :
Nonmagnetic facilities have been constructed at the KRISS for the precision determination of proton gyromagnetic ratio and other related experiments. They are composed of a wooden house, an observatory and a service building equipped with temperature control system. The Earth´s magnetic-field at the wooden house is monitored remotely by a fluxgate magnetometer, and compensated automatically down to 1 nT by a closed feedback loop with three-dimensional Helmholtz coils. Overall facilities and performances are presented
