| Abstract: | The wiggler magnetic measurement system is designed according to theoretical analysis and manufacture technology level. The main parameters which affect the character of the magnetic measurement are described and analyzed in detail. Accurate orientation and measure of Hall probe with synchronous acquisition of the position and magnetic field data are the main function of the magnetic field measurement device which is made up of air-thrust bearings, Magnetic instrument and control system. In z direction, the positioning accuracy and repeat positioning accuracy are less than 5 m and 2 m respectively. Measuring precision, repeat measuring precision and response frequency of Hall probe are 0.05%, 0.01% and 1 kHz respectively. Sampling rate of data acquisition card is more than 1000. |
