Experiences from nonevaporable getter-coated vacuum chambers at the MAX II synchrotron light source
(Color online) Vacuum system of cells 2 and 3 in the MAX II storage ring from (a) commissioning to July 2007, (b) July 2007 to July 2008, (c) July 2008 to April 2009, and (d) from April 2009 onward.
Drawings of the standard stainless steel dipole vacuum chamber (top) and the new NEG-coated copper dipole vacuum chamber (bottom).
(Color online) Pressure in the MAX II storage ring from February 2009 to July 2009. The solid line corresponds to the pressure in MAX II in 2003 (Ref. 21).
(Color online) Product of stored beam current and total lifetime in MAX II from August 2008 to July 2009. Where available, the products of current and lifetime limitations due to inelastic scattering, elastic scattering, and the Touschek effect are given. The lines correspond to the products of current and lifetime in MAX II in 2003 (Ref. 21).
(Color online) Count rate in the NaI detectors per and milliamperes stored current in MAX II from March 2009 to June 2009.
Relative proportions of the residual gases in MAX II during operation.
