The beamline and model is defined in the XAL beamline defintion file that Paul is maintaining:
http://www.slac.stanford.edu/cgi-wrap/cvsweb/ The production model is in:
Code Block |

/u1/lcls/physics/config/model/ |
This is the lcls.xdxf?rev=1.1&content-type=text/x-cvsweb-markup&cvsroot=LCLS
The default "accelerator" is loaded at startup. If you want to load a test model, Use Accelerator->Load Accelerator...

To create a knob, just do the following:
- Optionally, create a group
Group.
- Create a knob
Knob
- Add devices:
- Do this "by hand" if you know the PV. Eg YCOR:IN20:492:BDES
- Do this by "drilldown" (which uses physics name). In the Editor:
- Select a model sequence: Eg BXG TO BX01. Note that sequences are in alphabetical order. That is on the fix list.
- Select a device "type". Note that the type names given are:
1) SNS type names, which themselves use >1 name eg hcorr == dch == horrzcorr => X correctors.
2) and also flattened hierarchy of types, eg type "dipole" includes hcorr and vcorr. - Select a device name, by "physics name".
- Select FieldSet (not FieldRB). (issue: FieldRB should not be offered).
- Or calculate bump knobs
- Select a section of contiguous sequence of sections (a "combo sequence") Accelerator->Sequences
BXG TO BX01 - BX01 to BX02 works. - Knobs->(Make Horizontal Bumps | Make vertical bumps) Make Horizontal Bumps (Make Vertical Doesn't work, since it seems so many of our correctors are SLC!)
- For Horizontal Bumps: These setups were tested.
- Design Offset 3 (default) magnets - works (4 magnet doesn't work!)
- Design Angle 5 (default) magnets - works
- Live Offset 3 - works
- Live Angle 5 works - works
- For Vertical Bumps, select sections BXG to BX01 - QM15 to FV2
- Design Offset 3 (default) magnets - works, but they're mostly SLC magnets, so you can't connect and can't set them.
- Select a section of contiguous sequence of sections (a "combo sequence") Accelerator->Sequences
