Automation Control System of Nuclear Track Membrane Research and Design

摘要

The nuclear track membrane is the most precise microporous membrane in the world. It is a porous, plastic film with dense holes in it, each of which has the same shape and size. Nuclear track membranes are available in a variety of sizes ranging from 5 microns to 60 microns and pore sizes ranging from 0.2 microns to 15 microns. Density of the hole ranges from 1-10 to 9th power per square centimeter. The nuclear track membrane of the Institute of Modern Physics of the Chinese Academy of Sciences through heavy ions generated by the HIRFL forms microspores and then undergoes special chemical etching. It is widely used in electronics, medicine, filtration, and analysis. The control system of the nuclear track membrane has an important role in the entire production system. Due to the special beam radiation, the automation requirements of the control system is also very high. The automatic control system of nuclear track membrane production, from theoretical design to actual control construction is studied by this article. The main focus is the beam homogeneity correction control system and the production automation control system. The principle of beam uniformity correction, the implementation process, and the specific implementation of the automatic control system are studied in detail. Specific hardware deployment architecture and software design process are also discussed.
