We report 4.2-K photodesorption experiments in two quasi -- closed geometries-a simple tube and a tube with a coaxial perforated liner -- designed to manure separately the desorption coefficients of tightly bound and physisorbed molecules. The results are important for the beam tube vacuum of the next generation of superconducting proton colliders that have been contemplated-the 20-TeV Superconducting Super Collider (SSC) in the United States and the 7.3-TeV Large Hadron Collider (LHC) at CERN.
