Hi All,

I've now added the 18GeV-2col files to the eRhic -> collaboration -> Version-5.1.
This file has both  IR6 and IR8 squeezed to the same 5cm Beta*. This can be used to
test cancellation of chromatic functions using IR phase differences.

Hi All,

I've released the 18GeV lattice to share point. Included is a PDF for both
10GeV and 18GeV.

Hi All,

Sharepoint now has all the 10GeV version 5.1 electron storage ring MADX
files.
18GeV will follow shortly.
