  1. BDS Design Studies John Amann ILC Mechanical Engineering 10/24/06

  2. BDS Alcove Layout 4.5m x 6m x 3m Instrumentation/Control/Vacuum Racks Rack Mounted Power Supplies Freestanding 800kW Power Supply Amann 10/24/06

  3. PDL1 Area 4m Service Tunnel .75m Cable Penetration 20m Section High Density of Power Supplies 15 Rack Mount PS 23 Freestanding PS 3.25m floor Amann 10/24/06

  4. 4m Service Tunnel Installation Issues? 350kW Power Supply Fits Amann 10/24/06

  5. Tunnel Pocket to Accommodate 800kW PS 4m BDS Tunnel Need 2 Total for BDS 1 for Each BSY Tunnel Pocket Cable Tray 4m Service Tunnel 800kW PS Clearance Around Racks and PS Amann 10/24/06

  6. Push Pull IR 25m x 100m x 30m Amann 10/24/06

  7. Push Pull IR (Cavern Hidden) Mobile Shield Wall GLD Sized Detector Mobile Platform 20m x 30m Electronics/Cryo Shack 1m Shielded Amann 10/24/06

  8. Mobile Shield Wall Half Steel Reinforced Concrete 3m Thickness Interference with Service Tunnel Opening Structural Rib Overlapping Rib 25m Height 9m Base Amann 10/24/06

  9. Pac Man For BDS Tunnel Can not locate Pac Man on IR wall. Not enough clearance to open and close. Solution: Create Recessed Niche Recessed Niche Pac Man Open Pac Man Closed Amann 10/24/06

  10. Asymmetrical Pac Man Still need to think about Pac Man “snout” to span IR wall to detector. Should it be integrated into detector? Detector Pac Man Beam Line Support Here Minimize Unsupported Span ~3m Amann 10/24/06

  11. IR Concrete Floor Deformation Extreme Case 20,000psi Max Y Displacement = .6mm From CMS/ATLAS experience, need 5cm thick steel plates on IR Floor to prevent cracking. Amann 10/24/06

  12. Work in Progress…… • Design of beam line breaking point/location of SC magnets. • Design of Pac Man snout to enclose breaking point. • Air caster modules for mobile platform and shield wall. • Service tunnel entrance/access from IR. • More detailed IR floor deformation studies.
