【Abstract】 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.更多还原
