Beam-loss induced pressure rise of Large Hadron Collider collimator materials irradiated with 158  GeV/u In^{49+} ions at the CERN Super Proton Synchrotron

During heavy ion operation, large pressure rises, up to a few orders of magnitude, were observed at CERN, GSI, and BNL. The dynamic pressure rises were triggered by lost beam ions that impacted onto the vacuum chamber walls and desorbed about 10^{4} to 10^{7} molecules per ion. The deterioration of...
