Abstract:

Tests results are presented for the cryosorption of hydrogen on a commercially manufactured molecular sieve 5A panel operated near 20 K. The effects of repeated activations, water and air contamination under vacuum, and exposure to atmospheric conditions were observed. Using suitable operating techniques, pumping speeds near theoretical maximums were obtained.
