  • From lclshome -> User Dev Displays panel.
  • Run one of the matlab scripts xalRunModel or xalGetModel.

        Select a beamline.
         For example, select "*Cathode to Dump*" This runs the LCLS "Full Machine" model, from the LCLS Cathode to the main Dump. See [Why are all models from Cathode to some location|#whysameloc].

        Select whether to "*Run extant machine or design model? (x/d) \[d\]:*".
         Running the "design" model (choice "d") causes the XAL model to be run with the element setpoint values in the model input files. Those design setpoint values are, [to the extent possible, identical to the MAD design|#modeldiffs]. Running the "extant" model (choice "x") will cause the model execution to first replace the design values of beamline devices, with the actual readback values, as acquired through EPICS and AIDA, prior to running the envelope tracker.  That is, "extant" is equivalent to what was called "DATABASE" in the SLC modelling system; it describes the extant machine at the time the model is run.

      • Check the initial conditions which will be used for the model run. These are presently taken from the SLC marker point 80. You an check this with AIDAWeb beforehand (MARK:VX80:80//twiss MODE=5)
