This paper presents the studies of cryosorption pumping of He by charcoal at 4.2/sup 0/K and between 10 and 20/sup 0/K. We conclude that coconut charcoal at 4.2/sup 0/K is suitable for evacuating He from fusion reactors. A compound cryopump design, which utilizes cryocondensation for hydrogen isotopes and cryosorption for helium is also presented.
