Abstract

Cryogenic pumping is a means of achieving high vacuum by maintaining a temperature below the freezing temperature of a gas on the surface of a sorbent surface. The pumping action is accomplished either by condensation or adsorption of gases on the sorbent surface. The temperature on the surface can be achieved by using cryogenic liquids or closed cycle refrigerator. The scope of this project includes design and analysis of the pumping element like cryopannel and other related parts. The pumping behavior of different types of gases such as Nitrogen,Helium, Argon, etc will be studied on activated charcoal surfaces and without the charcoal. In this project cryopumping study will be carried out using a cryocooler based cooling media. The high vacuum environment necessary for many experiment like space experiments and degassing measurement system and very important requirement in plasma development technique. Cryopump is device which is used for producing very high vacuum environment. In the cryopump cooling will taking place by flow of coolant or by G-M Cryocoler. In this project we have developed the cryopannel according the cryocooler capacity of 1.5 watt at 10K temperature and conducted the experiment and calculated the pumping speed of cryopump with different gases.

Key Words

, capture coefficient, heat load , Cryopannel, GM Cryocooler, Activated charcoal.
