Standard LHC optics at 7 TeV with TCRYO collimators.

Description of this case:

In this case, the sequence has been modified (courtesy of R. Bruce): thin markers for collimators have been installed in the middle of the current 8.3T dipoles.
This corresponds to the situation where these dipoles have been replaced by two shorter 11 T dipoles, creating free space.
However, in this thin optics case, the dipoles have not been replaced. For IP1 and IP5: Beta*=0.55m; for IP2 and IP8: Beta*=3m.
