MVD routing: disks

  • Problems so far ... 

N t ffi i t ith thi l b l t

  • Not sufficient space, even with thinner global support
  • Required routing inside global MVD support
  • Solution ...  ... (!?)
  • Decrease outer radius of barrel layer 4 and strip disks
  • Global MVD support shifted inside
  • Global MVD support shifted inside

 Smallest impact of overall concepts in strip part  Sufficient space created in between global MVD  Sufficient space created in between global MVD

support and maximum outer radius of 150 mm

SLIDE 13

MVD routing: disks

  • Solution ...  ... (!?)
  • Decrease of outer radius barrel layer 4:

rmax = 140 mm – 5 mm  rmax = 135 mm

  • Global MVD support:

r = 137 mm ... 141 mm  Space: 8,228 mm2 Remark: Remark: Additional space at radii > 150 mm along CF for cooling pipes : 20 mm (width) up to min. r = 175 mm g p p ( ) p  Additional space outside r = 150 mm: > 1,400 mm2

  • Check:
  • Effects for strip disks
  • Coverage tests

Conclusion

  • Updated mass estimates (for mechanics input!)

in agreement with former specifiaction

  • First concept for MVD barrel routing

First concept for MVD barrel routing

  • Solution for internal routing of forward part

To be checked Question: Question:

Alternative routing of additional disks

  • What about routing into forward part

(e.g. GEM system) ?
