脉冲线测量波荡器磁场的研究

Development of a pulsed wire system for undulator measurement

介绍脉冲线测量波荡器磁场一、二次积分分布的原理和一套较高精度的脉冲线测量系统的研制,分析了传感器、实验环境、线的张力和波的反射性等因素对测量精度的影响。该系统对5周期波荡器模型的磁场测量结果与高精度Hall探头测量值作了比较,结果满意。

The pulsed wire method （PWM） is theoretically analyzed for developing a PWM system to measure the first and second integral field distribution of undulator. Effects of the sensor, the environment, tension of the wire and wave reflection are described in detail. An undulator model was measured by the pulsed wire system with minimum error caused by the effects. The results are compared with Hall probe method.
