[dsg-svt] RICH Assembly in EEL 124, SVT space needed in cleanroom

[Marco Mirazita]

Dear Walt,
thank you for these images.
I'm currently at jlab, I will stay till nov. 9 and next week also Dario 
and Sandro will be here.
It would be good if we could have a meeting to discuss the situation in 
EEL124.
Any time on monday 7 or tuesday 8 would be fine for us.
Thank you,
Marco
