Dear Amrit,
let me try to summarize my present understanding about
EEL-125 use.

Space: RICH assembling would likely need more space than
expected due to the complex procedure and several
delicate elements. However, looking at the screenshot
of Bob Miller, I realized the SVT+MM system will be
moved out of the clean room at the end of October.
This will free the space in time for the most critical
activity (aerogel assembling). To remove unnecessary
stuff or re-organize part of the services (i.e. tables)
might solve the issue without the need of moving
the SVT+MM in advance.

Clean: the RICH group has always scheduled a cleanup
action between the tasks to be performed before
the critical element assembling. This cleanup
has not been very well defined yet but the actions
Yuri is listing are all going in the same direction.
I am in favor of them. Who should do what has
to be agreeded, and RICH will cover his part by sure.

Of course, I might not have all the details under
control and I am at disposal to further discuss the
above points in order to reach a practical agreement.

Best regards, Marco.
