Good Morning,
I inspected the three piezo mounts with the stage unloaded from the system and found piezo post three's ceramic ball missing.  Evidently it had broken or sheared off the kinetic mount.
Additonally found the slider contact strip for the sample holders faraday cup connection had become bent and no longerr making suitable contact to the groundung pin on the sample holder.
Raith field service personnel are on their way and should be here in  an hour or so.  Caught them just as they were to leave from SFO to travel back back to Germany after another Bay area installation.
System is shut down to all users
