Hi Marc,

With Chuck help today, we moved the rack in the TEDF building where the 
Bigbite frame is located (where our GEM layer is installed). I don't 
really know the room number of the area but maybe Chuck could help me 
out here

Chuck also has prepared the gas cylinder to be used for the test and I 
believe everything is ready to go. So when you are available, we can go 
ahead with the installation.

I am not at JLab tomorrow so if you plan to work tomorrow, Chuck could 
help also. if not, I will be back at JLab on Thursday and we can plan 
accordingly

Please let me know

Best regards

Kondo
