1. Decay Solenoid – what do we have to do to make it work?

2. Work Strands Refurbishment Alignment –Shims and stops These tasks should be completed by the time Linde commissioning is complete (November 23 rd ?) Testing –Controls –Interfaces – Electrical and Pneumatic Positioning System for Installation

3. Refurbishment Method Statement and Risk Assessments in place 1 week’s work on exit end MLI Entry end MLI probably slightly less, BUT this includes repairing copper shield and investigating leak. Jenny Tomkins was originally lined up to do MLI, but will probably be too busy on other projects to do it all.

4. Alignment Requires shims and stops to be designed and procured –Design in progress Help required from Metrology (CC).

5. Test Position

6. Testing – Preparatory Work Create a level area for the Solenoid Test Position Specify and procure pipework for connecting Gas Panel to Solenoid Turret Position the Power Supply, Control Rack and Gas Panel –We need a safe place to store the Gas Panel (currently in R12) Make all the necessary electrical connections between the Solenoid, Fridge, Control Rack, Power Supply and Gas Panel. Connect up the vacuum pumps Software??

7. Controls – Update from Graham Charnley The rack is now complete except for the 48v back up supply. We are waiting for the battery charger to be delivered. Expected end Oct. Rack wiring checks next week External field cables complete by end this week except for DC cables, these to be supplied by Martin Hughes. Need to clarify latest delivery date to allow for software testing prior to delivery. Aiming for w/c 12th Nov but could be w/c 19th Nov DL will provide resource at RAL to connect field wiring for test position. DL require confirmation of actual date for this work ASAP to enable booking of travel and accommodation.

8. Final Installation Procure (?) and install pumping rig Re-orient transfer line –Need to book in DeMaCo for this? –Needs a support inside the DSA Need to design and procure positioning system – probably just a simple pulley.

9. Open Questions Can we get help for the MLI work? Is the power supply cabling for the test and final positions in hand? Can a temporary scaffold platform be made to support the Solenoid in the test position? What support is needed for moving the transfer line to the test position? What are the full implications of connecting all the solenoid systems in the DSA? –Do we need a high level platform? –Are cable routes agreed?
