CF Deliverables for XFD

• Provide a facility that promotes collaborative
  leading edge research in a pleasant working
  environment
• Structurally stable facility with low vibration
  (lt25nm 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

Revised LOB Program

• The 2 LOBs (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
  LOBs plus some additions)
• Current plan is to provide 3 larger LOBs to
  support more rapid buildout of beamlines and
  transfer of NSLS beamlines (20)

LOB Features

• Modular design can be added when needed without
  interrupting operation
• 3 _at_ 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 LOBs
• 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
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, LN2, GN2
• DI Water (Copper and Aluminum) by Accelerator
  Group

12
Stability Dependent on Conventional Facilities

• Stability goals driven by conventional facility
  design
• Stability of storage ring tunnel floor
• Vibration lt 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
• /- 0.1o C for 1 hour time constant
• Thermal stability of experimental floor
• /- 0.5o C for 1 hour time constant

13
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

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
