摘要
In Heavy-Ion Medical Machine (HIMM), it is very necessary to monitor the power supply's current value bythe data acquisition The hardware of the data acquisition monitor system is NI PXIe-6366 DAQ card, which has16-bits resolution, 8 differential channels, 2MS/s per channel's sample rate, and also has a good synchronizationperformance. The hardware architecture is shown in Fig. 1.
