The SCML-01 measurement system is capable of making real time measurement of
Maglev properties with one or many YBCO pieces and with a PM or PMGs. Figure 5.7a
shows a columnar liquid nitrogen vessel over a PMG. The columnar vessel includes
a YBCO bulk or an array of 2–7 YBCO bulks. This set-up was employed in on-board
HTS Maglev equipment over the PMGs (Fig. 5.7b). The on-board Maglev equipment
includes a rectangular-shaped liquid nitrogen vessel and an array of 43 YBCO bulk
