Vacuum Characterization of a Woven Carbon Fiber Cryosorber in Presence of $H_2$

Some of the cold bores of the Large Hadron Collider (LHC) will operate at 4.5K. In these elements, the desorbed H2 pressure will rapidly reach the saturated vapour pressure, 3 orders of magnitude larger than the design pressure. Therefore, the use of cryosorbers is mandatory to provide the required...

description Some of the cold bores of the Large Hadron Collider (LHC) will operate at 4.5K. In these elements, the desorbed H2 pressure will rapidly reach the saturated vapour pressure, 3 orders of magnitude larger than the design pressure. Therefore, the use of cryosorbers is mandatory to provide the required pumping capacity and pumping speed. The behaviour of a woven carbon fiber to be potentially used as a cryosorber has been studied under H2 injection. The pumping speed and capacity measured in the range 6 to 30 K are described. Observations made with an electron microscope are shown. A proposed pumping mechanism and the implications for the LHC are discussed.
