分压电路对X射线条纹相机成像稳定性的影响
Influence of voltage divider circuit on imaging stability of X-ray streak camera
摘要
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 functions for the two voltage dividers.Both theoretical analysis and experimental results show 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.关键词
