The accumulated downtime of each subsystem is shown in Fig. 5, with 99.73 h in total. Together with the trip
events listed in Table 5, it is shown that some trip events resulted in a long downtime. For example, a single cryo- Facility Status
genic event took about 6 h to effect a system recovery; this instance indicates the importance of great reliability
of these critical subsystems. (Reported by Chang-Hor Kuo)
