Abstract

In consideration of the demand of bremsstrahlung conversion target filament for accurate restoring in high-energetic particle burst experiments

a service device for target filament accurate restoring was designed. First

some key formulas of restoring system were derived according to the stereoscopic theory. Then

a scheme for design of an accurate restoring system of the micro target filament was proposed according to the real application. Finally

an experiment platform to simulate real conditions was established to test the restoring accuracy error of this system. The experiment results indicate that the accuracy error of this restoring system is 2%.The semi-physical simulation experiment illustrates that this restoring system reaches the accurate restoring of the bremsstrahlung conversion target filament in the high-energetic particle burst experiments. As the research object is a restoring system rather than a positioning system

it do not need to be calibrated

so there is no calibration error. The target filament accurate restoring system developed ensures the reliability of high energy electron beam burst experiments.
