Picture of R1 Chamber 2 just before installing first window
3/6/2012
Aluminized mylar windows have been installed on the first R1 chamber built at ISU. The chamber has been moved out of the clean room and has a 90/10 Ar/Co2 mixture flowing into the chamber.
Does JLab have any signal boards to send us so we can look for signals on sense wires?
The second chamber is inside the clean room having the pre-tensioners installed while it is on the floor before we mount it onto the spit. The A-frame was repositioned to reduce the interferance with the changing room.
A second A-frame has been moved onto the clean room floor and will be installed tomorrow.
Our goal will be to have two chambers mounted by Friday 3/9/2012 and begin stringing the second chamber on Monday 3/12/2012..
The clean room will be cleaned Friday afternoon because of all the equipment and drilling taking place. We have susended the use of smocks until we finish installing the second A-frame. The particle counts appear low enough to maintain the class 10,000 rating.
3/14/2012
Sector 3 is mounted on our first A-frame and ready for stringing.
The second A-frame is installed in the clean room.
Sector 6 is on the cleanroom floor and ready for pre-tensioning installation (Although we are short on pre-tensioning hardware but more is on its way).
Mallory and Marcie have finished wire wrapping Field wires on Sector 1--which is outside the cleanroom with gas flowing.
We plan to thoroughly re-sanitize the cleanroom today, replace all pre-filters, let the dust settle and start stringing Sector 3 tomorrow or Friday.
Our new Lead Stringer advertisement went out last Friday.
