9 BROOKHAVEN SCIENCE ASSOCIATES Floor Plan – CLOB 3rd

10 BROOKHAVEN SCIENCE ASSOCIATES Tunnel Design Roof and wall thicknesses generally driven by shielding criteria except inner wall in area of berm (just structural) Outer wall (ratchet wall) is HD concrete During T-I will study whether precast or poured in place provides best balance of technical and cost performance Tunnel floor thickness driven primarily by vibration criteria During T-I will do modeling to arrive at optimal thickness and section shape Rigidly connected to exp. floor to create monolithic floor Penetrations from above for power and cooling water Penetrations from sidewall for HVAC Supply and Return

11 BROOKHAVEN SCIENCE ASSOCIATES Tunnel Design - Ring Building Section

12 BROOKHAVEN SCIENCE ASSOCIATES Tunnel Access Egress for life safety achieved by exits at each service building location Large shielded doors for equipment access provided at Service buildings for tunnel entry Mandoors and labyrinth provided at each Service building Vehicle ramp to roll-up door at 2 nd floor of each Service Bldg provides equipment access to electrical mezzanine at top of tunnel RF & LINAC areas integrated with CLOB structure have similar access as Service Bldgs

13 BROOKHAVEN SCIENCE ASSOCIATES Service Bldgs

14 BROOKHAVEN SCIENCE ASSOCIATES Differential Settlement Measures to reduce potential for differential settlement include: Thorough geotechnical analysis of site to identify problem areas Minimize footprint over disturbed areas Set finished floor elevation for maximum cut and minimum fill Early site preparation contract for maximum time to cut, fill, compact and observe settlement prior to building contract. Monolithic slab design for tunnel and experimental floor High slab stiffness, Tunnel 36 ” ; Experimental Floor 18 ” Building loads isolated from tunnel and experimental floor slab Access corridor isolated from experimental floor slab

15 BROOKHAVEN SCIENCE ASSOCIATES Vibration Mitigation Measures to be implemented in conventional design include: “ Monolithic ” slab for accelerator and experimental floor Slab thickness and section changes based on vibration modeling results during Title I Possible use of polymer admixtures for enhanced damping characteristics Isolation of bldg structure from tunnel and slab Inertial bases and isolation of machinery Low flow velocity design for ducts and piping Limited use of duct and piping isolation to avoid conversion & transmission of low frequency vibration Commissioning of equipment and systems to include alignment, balancing & vibration measurement

16 BROOKHAVEN SCIENCE ASSOCIATES Utility Support Utilities run underground in center of ring and distributed to five service bldgs (one in CLOB RF/LINAC area) Minimizes pipe runs and pipe size in bldg proper Minimizes potential noise and vibration impacts Mechanical Utilities include: Chilled water from expansion of Central CHW plant Tower water from process cooling water tower Potable water, compressed air, sanitary etc. Electrical Utilities distributed via substation and load center at each services bldg

19 BROOKHAVEN SCIENCE ASSOCIATES Temperature stability Key temperature stability requirement is tunnel +/- 0.1C at a given location with respect to time. Requires high resolution industrial grade instruments and controls with excellent repeatability. Control scheme using programmable controllers and reheat with temperature reset capability Space temp setpoint of 85 F is nominally equivalent to process cooling water supply setpoint to minimize temperature gradients Should be readily achievable provided loads to accelerator components are relatively steady-state

20 BROOKHAVEN SCIENCE ASSOCIATES Tunnel Temperature Control

21 BROOKHAVEN SCIENCE ASSOCIATES Tunnel Air Distribution

22 BROOKHAVEN SCIENCE ASSOCIATES Control Room The Accelerator Control Room is located on the second floor of the CLOB above the LINAC-RF area Provides ready access to Tunnel, RF & LINAC areas and electrical mezzanine Computer room is adjacent to control room and control room operators meeting room Additional study is required to identify optimal cable routing which may indicate computer room may be more advantageously located on 1 st or 3 rd floor

23 BROOKHAVEN SCIENCE ASSOCIATES Schedule Conventional Facilities Schedule has been coordinated with Accelerator requirements. Construction sequencing will enable Availability of Ring Bldg for LINAC, booster and storage ring installation to begin – June 2011 LINAC & Booster can be sooner if required Control/Computer room availability in CLOB - August 2011 Conventional Construction complete - October 2011
