1. G.Barber - Imperial College London - EE Workshop 12-14 March 20021 EE Dee Assembly Contents:- Area Manipulator Future Plans

2. G.Barber - Imperial College London - EE Workshop 12-14 March 20022 Area At present we will be using the compound in Building 867. The plan is to move one of the Opal frames into this region and set it in place using concrete blocks to adjust the height. It will have the original Opal back plate fitted and the idea is to mount a plate to the front of this that has the CMS fixing points machined into it. The advantage of this is that we will be able to test installation of the super crystal modules in various areas by making small inexpensive plates and the support will be given by the original Opal backplate.

3. G.Barber - Imperial College London - EE Workshop 12-14 March 20023 Manipulator We are developing a super crystal manipulator at Imperial College that has not only to positions the SC’s on the Dee but also allows an ‘in place’ tilt to enable the Saclay monitoring fibres to be introduced into the back. We hope to bring this manipulator arm to Cern in the next two months to prove/develop this procedure. This will then be the basis for the assembly chapter of the EDR.

6. G.Barber - Imperial College London - EE Workshop 12-14 March 20026 Future Work The next 3 months will be spent developing the equipment and technique needed to assemble the dees. It will not be the final scheme but we need to be confident enough in the philosophy to present it in the EDR. It can be improved and adapted over the coming months/years to accommodate any changes that may happen to the design. It is important to develop ‘a feel’ for handling the super crystals and with this we can adapt the equipment to achieve the best (and for best you could say the simplest) solutions.
