Pac Man For BDS Tunnel

Recessed Niche Pac Man Open

Pac Man Closed

Can not locate Pac Man on IR wall.Not enough clearance to open and close.Solution: Create Recessed Niche

Asymmetrical Pac Man

Beam Line Support Here Minimize Unsupported Span~3m

Still need to think about Pac Man “snout” to span IR wall to detector.Should it be integrated into detector?

IR Concrete Floor DeformationExtreme Case 20,000psi

Max Y Displacement = .6mm

From CMS/ATLAS experience,need 5cm thick steel plates on IR Floor to prevent cracking.

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.
