Project Nr. 2.1 “Introduction of technological research and development of an optimized cathode-ray heater for the production of high-purity materials” began

Work program “Growth and work” 1.2.1. Specific objective 1.2.1.1 Specific objective “Increasing private sector investment in R&D”. Within the framework of the event “Support for the Development of New Products and Technologies in Competence Centers”, SIA “MAŠĪNBŪVES KOMPETENCES CENTRS” implements project No.1.2.1.1 / 18 / A / 008 “Engineering Competence Center” from April 1, 2019 to December 31, 2021. ,
On April 1, 2019, KEPP EU jointly with the cooperation partner SIA Center for Analysis and Research of Processes, as part of the project Center for Competence of Mechanical Engineering, launched the research project Nr. 2.1 Introduction of technological research and development of an optimized cathode-ray heater for the production of high-purity materials.
The aim of this research project is to eliminate sources of impurities in silicon crystals grown using electron beam melting technology. Impurities enter the silicon alloy in the form of ions, which arise as a result of the interaction of the electron beam with the materials of the device. Design and testing of an electron-beam heater will be carried out by combining the previous study 2.3 “Modeling the plasma charge shape of electron-beam heaters and optimizing its shape to improve control of the crystal growth process” under the project “Creation of a center of competence in mechanical engineering” (id. 1.2.1.1 / 16 / A). / 003) the scientific results of the current project were obtained.
A simulation of the magnetic particle separation process will be performed to determine the required system parameters. An advanced electron beam heater will be tested and the concentration levels of impurities in the resulting product will be studied. The plant will be reconstructed using a new electron-beam heater. The resulting finished product will be tested for quality and compared with market products.
As a result, it is planned to develop a prototype of an electron-beam heater, which has no analogues on the market and can produce high-purity materials.
The study is planned to be carried out before November 30, 2021.
The total project cost is estimated at 406,423.57 euros, including 299,804.14 euros from the European Regional Development Fund.
