Vacuum Technology & Process Application

ABOUT THE COURSE: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.INTENDED AUDIENCE:UG, PG, Research Scholar, Industry Personnel and college teachersINDUSTRY SUPPORT:Electronic/Electrical/Pharma/Chemical/Metallurgical/food processing/nuclear/space sectors; BHEL/Crompton Greaves/Applied Materials/Defence laboratories/ Reddy Labs/ISRO/DAE/Aurobindo Pharma/BARC/NFC & vacuum industries. I have offered this course 30 times as self-sponsored under CEP programme of IIT Kharagpur
