5 How to attach the table to the floor TMC table Concrete polymer? Flat steel plate Bolt plate to floor Floor

6 Current QD0 configuration 610mm 50mm beam 1200mm T-plate 300mm (from Ghyslain’s drawing) 260mm Height to compensate! 30mm Idea for 260mm support is to have a bottom plate clamped to the bloc with some possibility of adjusting the position with big screws

8 Even if we don’t have the magnets yet, we can see that the magnet is at the same position as the “front” cam motor (without the winding)

9 Solid Wire Sextupoles 11/27/07 For the FD we will use 2 solid wire conductor sextupoles with 2.13” bore. These magnets have a position adjuster attached to the yoke. These magnets are located at KEK and will be shipped to Annecy. The magnet/adjuster assembly would be bolted to the sextupole mover v-block stage. To do this, new holes must be drilled and tapped in the v-block stage to match the position adjuster base plate. Already adjustable: our support will not need to be adjustable?

10 Solid Wire Sextupoles 11/27/07 Summary of important dimensions: Sextupole Core: height to magnetic center = 8.819”/2 = 4.410” or mm Position Adjuster: nominal height as seen in previous slide = 4.17” or mm approximate minimum height = 3.42” or 86.87mm maximum height = depends on bolt length, should keep at nominal or lower Sextupole Mover: height from bottom of T-plate to top v-block stage = ~ ” or ~ mm (measurement taken from mover in Justin May’s office, may have different dimensions from movers at Annecy) NOTE!!! Because this configuration is newly conceived, no assembly drawings exist which depict the dimensions of magnetic center referenced from bottom of mover T-plate. We need this dimension for support design
