Spaces


Experimental Floor Concept

• Divided into 5 clusters

• Service Bldg supports all services within the cluster

• Six sectors/Cluster

• CLOB & Service Bldgs contain all Accelerator systems

• Ring, CLOB, LOB 1 & service bldgs are base scope

• LOB’s 2,3,4 can be added as needed w/o interruption


Experimental Floor Arrangement


Experimental Floor - Ring Building Section


CLOB Features

• Space for 190 Offices, 8 labs• Nominally 30 User Offices, 5 User labs from the total• Possible 400 seat Conference Center addition w/ vendor area and

three breakout rooms• Lobby and User Reception area• 2nd floor viewing gallery overlooking experimental floor• Bridge to electrical mezzanine and control room & RF/LINAC

areas• Close Proximity to future:

• JPSI Building• Guest house


Floor Plan – CLOB 1st


Floor Plan - CLOB 2nd


Floor Plan – CLOB 3rd


LOB Features

• Modular design – can be added when needed without interrupting operation• 11,000 SF each – Serves six sectors• 30 offices w/ conference space, interaction areas, lavs, showers• 5 labs intended for shared use• Shipping/Receiving/Storage area & chemical storage area• Potential for expansion for more offices if needed

• Egress provided for personnel and large items at each LOB• Loading area with exterior roll-up door• Roll-up door from each lab onto the experimental floor

• Designed to minimize impacts to future long beamlines


Lab – Office Building


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


Vibration Mitigation

• Measures to be implemented in conventional design include:• “Monolithic” slab for accelerator and experimental floor• Slab thickness and section changes will be based on vibration modeling

results• Possible use of polymer admixtures for enhanced damping

characteristics – likely use for access corridor• 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


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• Only needed service piping will be run in experimental area• Minimizes potential noise and vibration impacts

• Services provided at each BL include:• Electric Power Panel at Ratchet Wall, 75-95kW/Cell, 120/208V• Cooling Water, HVAC Supply Air, Exhaust• Compressed Air, LN2, GN2

• DI Water (Copper and Aluminum) by Accelerator Group


Utility Support


Temperature Stability

• Key temperature stability requirement is tunnel air @ +/- 0.1C at a given location with respect to time.• Requires high resolution industrial grade instruments and

controls with excellent repeatability.• 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

• Experimental Floor Temperature • Cooling: 75 F +/- 1 F, 50% RH +/- 10% RH• Heating: 75 F +/- 1F, 30% RH +/- 10% RH


Experimental Floor Air Distribution


Schedule

• Construction sequencing will enable • Availability of Ring Bldg for LINAC, booster and storage ring

installation to begin as early as March 2010• Beneficial Occupancy of Ring Building & LOB - June 2011• Control/Computer room availability & CLOB BO - August 2011• Conventional Construction complete - October 2011
