Vacuum Technology & Process Application

By Prof. V. Vasudeva Rao   |   IIT Kharagpur
Learners enrolled: 440
This course starts with a lucid introduction to basic concepts & applications of vacuum technology. This is followed by production, measurement, system design, process applications along with trouble shooting and maintenance of vacuum systems. This course is quite relevant to the modern process technologies like mobile/TV/Computer manufacturing, semiconductor processing, solar energy, metallurgical processing and steel degassing, drying of pharmaceutical intermediates and processed packed food. This course also serves Indian space and nuclear sectors as vacuum is essential for space simulation, thermovac chambers for satellite testing, particle accelerators and nuclear fusion for future clean energy.
