Cryopump is a vacuum pump that pumps the gases and vapors by condensing them on a cold surface, by adsorption on porous surfaces or by trapping mechanism. Helium gas which is very light can only be pumped by Cryoadsorption cryopump. Cryoadsorption cryopump cannot be used when working for continuous operation as it pumps the effluent till the saturation state is achieved. Then the absorbed gases are required to be removed by warming up cryopanels. Hence, regeneration analysis of cryopump is very important to study. In cryoadsorption cryopump, charcoal-coated cryopanels are cooled down to 4.5 K with supercritical helium. In this review paper, we estimated hydraulic parameters i.e., mass flow rate, heat load, cool-down and warm up time scales and pressure drop, which are majorly involved in cryopump operation.Keywords: cryopump, pressure drop, hydroformed cryopanelCite this Article:Ramani K, Makadia J.
