Update on Alignment kit and Stave 250 frame

and thoughts for Stave 130

M.Gibson (RAL)7/6/13

1

• Status of infrastructure for stave 250 module mounting and testing.

• Stave 130 ‘stuff’

Stave 250 Module Mounting• Now have 3 modified jigs, with 2 assembled onto the bridges using the pre-loaded bearing principle.

• Ivan has started looking at the problem or array handling given the data from Tim, and using Peters drawing.

• A set of data for manual positioning has been created.

• Stave expected 5th June (wed) with the stave frame expected on the 12th . (Wed).

• I am assuming no Kapton between modules ‘cos I havn’t made any or modified the glue pattern.

• Mike is away until June 10th (Monday) at earliest. Need him to bend the linking pipes stave to frame and Ian, Richard, or John to weld the ends on.

• Plenty to do 5th to 12th as we will have to measure the kapton to see if its like the drawing and form a plan. So 19th (Wed) or 20th June we might be in a position to stick a module.

Stave 250 testing infrastructure

• Installation of the CO2 system is progressing. Bunds are installed, along with N2 (for flushing of the test volume).

• The SS pipe installation is progressing slowly because we have lost Mike so I am doing it!

• A design for all the necessary interlocks now exists. Needs converting to a real circuit and the items ordering.

• Automatic fume extraction fan, trunking, and hole in window all exist, just needs fitting.

• I have the CO2 solenoid on my desk and the connectors arrived 30/5/13.

• CO2 detection system is on order and due anytime now.

• Still not done anything about measuring the liquid level of CO2 in the bottles. But ultrasonics looks like the way forwards.
