2 Previous splitting of disk into Dees
Upper Dee: modules start and end on Z+ side Lower Dee: modules start and end on Z- side Nice straight edge along which disk can be split Note that there are more modules on upper Dee than on lower → bad for power balancing

3 Circuits de refroidissement
Circuits distribués dans 7 secteurs Chaque circuit et différent! Mais aussi pour le Dee inférieur → 14 circuits différents par disque 4 différent types de disque → 56 différents circuits!

4 Cost impact Latest pipes from Minitubes Gluing inserts onto pipes
2.20 x 1.95mm diameter Raw tube: €54.40/m Bending 2x sector 1 + 2x sector 2: €2,200 Tooling per sector: €3950 Gluing inserts onto pipes 1x jig sector 2: €3980 Large jigs for final Dee curing Per Dee type: one jig each side of Dee (jigs different) 4 Dee types / double disk type in old layout → 8 per TEDD 16 different jigs in total Multiplying the numbers in red by 56 gives pause for thought!

5 Il nous convient de rendre les deux Dees identiques (sans changer le disposition de base des modules silicium)

6 Identical paths S1/S3 and S4/S8 (orange)
At the Dee interface, the problem of routing between C-foams is different than at φ=90, and the paths deviate in these regions But same bending jig could be used for all 4 sectors → two jigs per disk!

7 Note: now only 4 return pipes per disk with ‘free’ path
Reduced overlap between S3/S4 reduces maximum pipe length from 7.08m to 6,71m Note: now only 4 return pipes per disk with ‘free’ path Odd rings #mods PS #mods 2S Power (W) L_CAD S1 12 16,5 184 6,60 S2 14 15 192 6,71 S3 6,61 S4 S5 S6

8 TEDD_1: all cooling loops
Odd + Even disks

9 Summary table → ~2 → 8 → 6,71 Original model
