摘要:
在X射线条纹相机静态测试中,发现分压电路的稳定性显著影响条纹相机成像性能.为提高成像稳定性,对分压电路进行测试,发现分压电路输出不稳定性由电流热效应导致,对此采用小电流分压电路方法,以降低电流热效应.测试和比较了两种分压电路的电压、电流输出,条纹相机静态成像性能和系统调制传递函数.理论分析和实验结果表明,相机在使用小电流分压电路加电20 min后,工作电流、温度及电子透镜焦距分别改变了1.4%、7.5%和0.14%,静态成像以及系统调制传递函数均优于原有方法.
Abstract:
In the static test of the X-ray streak camera,it is shown that the stability of the voltage divider circuit significantly affects the imaging performance of the streak camera. In order to improve the imaging stability, we analyze the voltage divider circuit. We find that the output instability of the voltage divider circuit is caused by the current thermal effect.The voltage circuit with smaller current is adopted to reduce the current thermal effect. We test and compare the voltages, current outputs, the static imaging performances of the streak cameras and the system modulation transfer functionsforthe two voltage dividers. Both theoretical analysis and experimental resultsshow that after the camera has been powered with the smaller current divider circuit for 20 min, the operating current, the system temperature and electron lens focal length change by 1.4%, 7.5% and 0.14%, respectively.And the static image quality and modulation transfer function are improved.
