| Abstract: | The superconducting magnet is a large caliber,high magnetic field device,The LabVIEW was selected as data acquisition and measure and control system.There are six low temperature sensors,installed in magnet helium vessel and cooling shield respectively,including three carbon resistance thermometer,two platinum resistance thermometer Pt100 and one Pt1000,which are applied to observe the temperature of magnet;There is a superconducting helium liquidometer,which is applied to observe the liquid helium level.Based magnet parameters,a set of DC power supply and the quench protection system are developed for the magnet so as to assure it operate safely.All data acquisition is by DAQ6251 that is inserted in PXI made in NI,data acquisition and human machine interface are programmed by LabVIEW. |
