Cryopumping of atomic hydrogen
The pumping speed for the cryopumping of an atomic hydrogen beam was measured. Measurements were made for cryocondensation, cryosorption, and differential pumping. The pumping speed for atomic hydrogen was observed to be much smaller than the pumping speed for molecular hydrogen. It is believed that this is due to the energy released during the recombination of the atomic hydrogen.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69754/2/RSINAK-62-11-2738-1.pd
Single spin asymmetry measurements for inclusive productions in and \pi^-+\p_{\uparrow}\to \pi^0+X reactions at 70 and 40 GeV respectively
The inclusive asymmetries were measured in reactions and at 70 and 40 GeV/c respectively. The
measurements were made at the central region (for the first reaction) and
asymmetry is compatible with zero in the entire measured region. For the
second reaction the asymmetry is zero for small region () and increases with growth of . Averaged
over the interval the asymmetry was .Comment: 4 pages, 2 figures; Presented at SPIN-2004 at Trieste, October
