Abstract
Electron beam accelerators are used in many applications, such as basic physical research, chemistry, medicine, molecular biology, microelectronics, agriculture and industry, among others. The majority of the accelerators have electrons from a hot tungsten filament and their energy is increased as it passes through an electric field in the vacuum chamber. For industrial purposes, the most common model is Dynamitron®. At IPEN-CNEN/SP, there is an electron beam accelerator Dynamitron® Type (Manufactured by RDI - Radiation Dynamics Inc., 1978) model DC1500/25/4. The technology applied was available in the 60´s and 70´s, but, nowadays is obsolete. Moreover, there are not original spare parts for this equipment any longer. The aim of this work is to develop a nationalized automated operation system for the accelerator, to replace the old equipment. electron beam, accelerator, automated system, Dynamitron®
Highlights
Particle accelerators are sophisticated and expensive equipment used to accelerate electrically charged particles such as electrons, protons and ions, besides less common particles, like positrons
Its various applications range from industry, medicine, basic physical research, molecular biology, chemistry and agriculture, among others
At the end of the 1920 ́s, it became clear that natural radioactive sources were not enough anymore and the ion accelerators were necessary in the development and research of nuclear physics
Summary
Particle accelerators are sophisticated and expensive equipment used to accelerate electrically charged particles such as electrons, protons and ions, besides less common particles, like positrons. The equipment and process are the result of years of research and dedication of dozens of thousands of professionals, in many countries. Its various applications range from industry, medicine, basic physical research, molecular biology, chemistry and agriculture, among others. At the end of the 1920 ́s, it became clear that natural radioactive sources were not enough anymore and the ion accelerators were necessary in the development and research of nuclear physics. At the beginning of the 1930 ́s, different types of accelerators started to be developed, almost simultaneously: the linear high frequency accelerator, the Circular and the Direct Current accelerator. Cockroft and Walton built their first generator of 600 keV, cascade type, in 1932. Almost at the same time, Robert Van de Graff built his 1.5 MeV machine
