The LENS_3X limit switch (switched when driving towards the chamber center) is broken and must be replaced, hence further work is required on the next JJ visit 9/10 Jan (TBC)

The in vacuum components also need further work during the above visit. The lens that lost alignment during commissioning was also found to be more severley damaged than anticipated - the B4C guard is cracked and this deposited some fragments under the lens. All lens cassettes will be exchanged, rebuilt and realigned in Jan.

The patch panel has been removed for rework (to switch motor direction)

The Be lenses seem to be in exactly the same condition as 'new'
