|FACET 2 Lattice Description|
|Accelerator Directorate||FACET and Test Beam facilities||Lattice Descriptions||Device Database|
This is the home page of the lattice descriptions of the Facility for Accelerator Science and Experimental Test Beams-II (FACET II) accelerator.
The lattice descriptions are expressed in the Methodical Accelerator Design (MAD) language (version 8). There are also similar pages for the LCLS and planned LCLS II accelerators.
The following are the FACET-II MAD input files in SLAC's CVS:
|Main command file (e-)||FACET2e.mad8|
|Matching command file (e-)||FACET2e_match.mad8|
|Patch file (e-)||FACET2e_patch.mad8|
|Master definitions (e-)||FACET2e_master.xsif|
|Main command file (e+)||FACET2p.mad8|
|Matching command file (e+)||FACET2p_match.mad8|
|Patch file (e+)||FACET2p_patch.mad8|
|Master definitions (e+)||FACET2p_master.xsif|
|Main command file (SCAV e-)||FACET2s.mad8|
|Matching command file (SCAV e-)||FACET2s_match.mad8|
The MAD output results of the above files, are in directories under
/afs/slac/www/grp/ad/model/output/facet2/. Those output
directories containing files resulting from official lattice releases, are named after their
release date in the form ddMMMyy, eg "22DEC17". The date string is also used as the CVS tag of their release. The data of official releases should also be found in the Oracle database (see below). Additionally, the
latest output is always in
/afs/slac/www/grp/ad/model/output/facet2/latest/. Note that the "latest" link may contain results from
lattice development following the last release - so it is not necessarily the output of the most recent official release. That is, "latest" may contain follow-ups, or addenda, to files in an official release.
