Updates to the MAX IV 3 GeV Storage Ring Lattice
Last revised: June 11, 2012
The lattice for the MAX IV 3 GeV storage ring has been modified to include results from detailed vacuum engineering design. A new lattice m4-20111213-420  has been branched off from the previous m4-20110117-420 version. As the optics have not been modified, beam dynamics studies performed with the previous m4-20110117-420 branch will remain valid. The previous lattices will be retained, however, a new bare lattice file m4-20111213-420-bare is being made available in order to reflect updated positions and lengths of the elements contained in the lattice files. This document describes the changes that resulted in the new m4-20111213-420 branch. A list of current lattice files and their purpose is appended.
