[BTeam] CERN Accelerator School: Vacuum for Particle Accelerators

[Jay Benesch]

Five papers showed up in arxiv today.  I expect more in coming days.   Like the Beam Instrumentation school, some may not have the subject line above in Comments, so the query below will not cover all.  But it's a start.  Checking https://arxiv.org/list/physics.acc-ph/recent daily is another option.

    Cleaning and Surface Properties

    Authors: Mauro Taborelli

    Abstract: Principles of the precision cleaning dedicated to ultra-high vacuum applications are reviewed together with the techniques for the evaluation of surface cleanliness. Methods to verify the effectiveness of cleaning procedures are addressed. Examples are presented to illustrate the influence of packaging and storage on the recontamination of the surface after cleaning. Finally, the effect of contami… ▽ More

    Cryopumping and Vacuum Systems

    Authors: Vincent Baglin

    Abstract: The understanding of complex and/or large vacuum systems operating at cryogenic temperatures requires a specific knowledge of the vacuum science at such temperatures. At room temperature, molecules with a low binding energy to a surface are not pumped. However, at cryogenic temperatures, their sojourn time is significantly increased, thanks to the temperature reduction, which allow a "cryopumping"… ▽ More

    Materials & Properties: Mechanical Behaviour

    Authors: Cedric Garion

    Abstract: All systems are expected to be designed to fulfil their functions over their requested lifetime. Nevertheless, failure of a system may occur, and this is unfortunately, true also for vacuum systems. From a mechanical point of view, buckling, leak by fatigue crack propagation, rupture of a fixed support under unbalanced vacuum force... may happen. To well understand and anticipate the behaviour of… ▽ More

    Fundamentals of Vacuum Physics and Technology

    Authors: Eshraq Al-Dmour

    Abstract: A good vacuum performance in particle accelerators is vital for their successful operation. The reasons why a good vacuum is needed, together with the basics of vacuum physics and technology and the main gas sources inside the vacuum system, are presented here.
