2 BROOKHAVEN SCIENCE ASSOCIATES Outline Conventional Facilities Deliverables for XFD Overview of Conventional Facilities Scope Experimental Floor Beamline Support Space – LOB ’ s Utility Services for XFD Stability Strategy Schedule Dependency

3 BROOKHAVEN SCIENCE ASSOCIATES CF Deliverables for XFD Provide a facility that promotes collaborative leading edge research in a pleasant working environment Structurally stable facility with low vibration (<25nm Rms) Tunnel design that provides required shielding and accessibility Experimental floor temperature stability of +/- 0.5 deg C Utility capacity & shielding for up to 3.6 GeV operation Utility services for anticipated full suite of beamlines (60m) Facility layout that enables future long beamlines Facility design enabling future expansion to support full beamline build-out

7 BROOKHAVEN SCIENCE ASSOCIATES Facility Program

8 BROOKHAVEN SCIENCE ASSOCIATES Revised LOB Program The 2 LOB ’ s (1 integrated in CLOB, the other standalone) in CDR were insufficient to support full beamline buildout Intended to support initial suite of beamlines (~5 - 10) Would require substantial additional construction to support future beamlines (at least 3 more LOB ’ s plus some additions) Current plan is to provide 3 larger LOB ’ s to support more rapid buildout of beamlines and transfer of NSLS beamlines (~20)

10 BROOKHAVEN SCIENCE ASSOCIATES LOB Features Modular design – can be added when needed without interrupting operation 21,000 SF each – Each serves six sectors 72 offices w/ conference space, interaction areas, lavs, showers 6 labs - intended for shared use Shipping/Receiving/Storage area & chemical storage area Potential for expansion for 2 more LOB ’ s Egress provided for personnel and large items at each LOB Loading area with exterior roll-up door Double-door from each lab onto the experimental floor Designed to minimize impacts to future long beamlines

11 BROOKHAVEN SCIENCE ASSOCIATES Beamline Utility Support 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, LN 2, GN 2 DI Water (Copper and Aluminum) by Accelerator Group

12 BROOKHAVEN SCIENCE ASSOCIATES Stability Dependent on Conventional Facilities Stability goals driven by conventional facility design Stability of storage ring tunnel floor Vibration < 25 nm rms from PSD from 4-50hz (vertical) Stability of experimental floor Vibration level of ~ 25 nm rms (vertical) from PSD from 4-50hz for general floor area Vibration level for 1 nm resolution beam lines requires further definition but appears achievable with proper correlation Thermal stability of storage ring tunnel environment +/- 0.1 o C for 1 hour time constant Thermal stability of experimental floor +/- 0.5 o C for 1 hour time constant

13 BROOKHAVEN SCIENCE ASSOCIATES CF Program for Vibration Management Assessment of “ green-field ” conditions Studies by Colin-Gordon Associates & N. Simos On-going monitoring program Identification and mitigation of cultural sources (where feasible) FE Modeling of site and facility design Needed to understand & predict facility response Design optimization tool Analysis of other facilities (CFN, APS & SPring 8 thus far) Draw upon lessons learned Provide input for model Model performance verification During & after construction, implement monitoring and maintenance program

14 BROOKHAVEN SCIENCE ASSOCIATES Ring Building Section Non-vibrating Equipment Need to assure that vibration mitigation measures are carried out at Ring building interfaces with other structures and where systems enter building or tunnel Section at Lab Office Building and Service Building Rotating Machinery Distance determined by modeling & empirical analysis

15 BROOKHAVEN SCIENCE ASSOCIATES Schedule Dependency Conventional Facilities are the critical path until facilities are turned over to Accelerator and Experimental Divisions Critical Interfaces CF needs Beamline scope and design criteria during T-I and T-II design to assure conventional facilitis will meet XFD requirements – (especially for 1 nm & 0.1 meV resolution and long beam lines) XFD requires Beneficial Occupancy of experimental floor as soon as possible to meet beamline installation schedule Interface managers to be designated shortly CFD, XFD and ASD meet weekly as part of schedule task force to assure schedule needs are coordinated Currently assessing revised funding profile impacts
