Development of the new nozzle and detector system in thegas-phase electron diffraction apparatus

本研究项目的目的是对气相电子衍射装置进行改造。在本项目中，我们设计并制造了一种新的喷嘴系统，用于在装置的真空室中喷射气体样品，并进行了改进，以更好地处理和多功能的能力。我们还研制了一种新的衍射图样检测系统。新的XYZ型步进机械手的引入，使喷嘴的精确控制变得容易。我公司开发了高温裂解真空线，由石英管和不锈钢管组成。该系统安装在衍射室旁边，并与XYZ工作台上的喷嘴相连。最后，我们利用这种新型喷嘴构造了原型装置，并进行了一些实验，观察了气相中小分子的衍射图样。

The purpose of this research project is the renovation of the gas-phase electrondiffraction apparatus. In this project, we have designed and made a new nozzle systemfor the jet gas samples in the vacuum chamber of the apparatus, have modified forbetter handling and multifunctional capability. We have also developed a newdetection system of the diffraction patterns. The introduction of new XYZ-stagemanipulator has made it easier to get the precise control of the nozzle. We havedeveloped the high-temperature-pyrolysis vacuum line, made from the quartz tube andstainless-steel pipes. This system have been settled beside the diffraction chamber andit was connected to the nozzle on the XYZ-stage. Finally, we have constructed theprototype apparatus using the new nozzle and have carried out some experiments toobserve the diffraction pattern of small molecule in the gas phase..
