Abstract
The present study describes about superconducting magnets coupled with two kinds of disk type MHD generators. One is coupled with a disk generator in the closed cycle MHD experimental facility FUJI-1. The other one is for a full scale disk MHD generator. These are split-pair magnets.
In the magnet for FUJI-1 facility, a unique structure which supports the coils against the electromagnetic force has been fablicated and the magnet has been operating stably. During MHD power generation experiments, an induced voltage across the terminals of the coils were measured. A magnitude of the Faraday current in the generator was calculated from this induced voltage.
A possible construction of magnets for a full scale disk MHD generator is indicated. It is suggested that a high performance of the generator (output power density of 0.3_??_1GW/m3) can be obtained with high magnetic field up to 10 T.
