welding, the YBCO temperature must be limited during welding. After leak detection
of the sealed can, dry nitrogen gas of slightly more than one atmospheric pressure
is pumped into the can and it is permanently sealed. After 10 years of operation, the
can has been opened and YBCO bulks have been removed. Test results show that the
performance of the YBCO bulks remain unchanged (see Section 6.20).
The sealed cans are fixed firmly in the liquid nitrogen vessel. Figure 6.55c shows
the on-board HTS Maglev equipment completely assembled. The on-board Maglev
equipment is connected rigidly to the two sides of the vehicle body.
6.16 Experimental results of the on-board Maglev equipment
The levitation forces on a single on-board HTS Maglev equipment above the PMG were
measured with the SCML-01 HTS Maglev measurement system. The measurement
method is described in Section 6.3. During the experiment, the on-board HTS Maglev
