The gradient system in SV is called XFD. It contains three gradient amplifiers XFA and one
gradient power supply XFD-PS. They are all water-cooled. A leak sensor is installed in front of
XFD to detect leakage of water pipe connectors. XFD slew rate is 100, which is twice as
much as HFD-lite used in HDe system.
