Linac Locking - Phase Locker IOC PVs [sioc-sys0-ms10]
Currently, there is no phase locker test stand in Dev and hence only the Production display is availableDev and hence only the Production display is available.
To launch the linac locking dashboard GUI in Production, log onto the appropriate host (Production ==> lcls-srv01) and then run the command mslk_dashboard:

Upon running the command successfully, the following display is invoked. Choose Phase Locker Expert to monitor the phase locker IOC.
Note that the preferred way of accessing the display is the one shown above. However, below, we include instructions on how to launch the old display directly if needed.
To access and launch the display in Production, follow the steps outlined below.

The Phase Locker Expert is an engineering screen intended to be used by the firmware engineer for tuning until a locked state is achieved.
The registers have been tuned to achieve a lock in Production. See below the display with the selected values. These values are also captured by autosave.
The released software will be made available in the main IOC release area post-deployment (Dev: /afs/slac/g/lcls/epics/iocTop/masterSource/, Production:/usr/local/lcls/epics/iocTop/masterSource/). See below for the specific repositories and tags.
