电子散射实验用于研究原子核和核子的结构及其性质,它依靠谱仪偏转磁铁前后的多丝正比室和多丝漂移室所记录的粒子位置结合计算机软件来决定粒子的轨迹及其动量,作为一个为它服务的多丝正比室就应当具有一定的空间分辨才能满足谱仪对定位精度及动量分辨的要求,从而提供粒子空间位置的信息。 根据以上要求,针对本组设计制作的多丝正比室(有效面积1.2×3cm~2,丝距1mm,位置分辨50μm),我们设计制作了一套多丝室电子学系统,并与多丝正比室一起进行了初步的线测试,从实验结果可以看出,该电子学系统是廉价、简单和符合电子散射实验
The electron scattering experiment is used to study the structure and properties of nuclei and nuclei. It relies on the positions of the particles recorded by the multi-filament proportional chambers before and after the deflection yoke of the spectrometer and the multi-wire drift chamber to determine the trajectory and momentum of the particles. A multi-filament proportional chamber serving it should have some spatial resolution to meet the requirements of the spectrometer for positioning accuracy and momentum resolution so as to provide information on the position of the particle in space. According to the above requirements, we design and produce a multi-wire room electronic system designed for the multi-wire proportional room (effective area 1.2 × 3cm ~ 2, pitch 1mm, position resolution 50μm) Room with a preliminary line test, the experimental results can be seen that the electronic system is cheap, simple and in line with the electron scattering experiment
