LIGO Hanford Observatory Infrastructure

1
LIGO Hanford Observatory Infrastructure

• Frederick J. Raab, LIGO Hanford Observatory

2
Facilities Infrastructure

• LIGO Hanford Observatory facilities comparable to
  a moderately-sized hi-tech college campus
• 10 buildings w/ 100,000 air-conditioned sq ft
• 70,000 sq ft are moderate to high-level clean
  laboratories
• 475,000 sq ft of total enclosed space
• 6 miles of roads, parking spaces for 80 vehicles
• 10,000 cu meters of high to ultra-high vacuum
  systems, 5 miles long, with gt 500 control
  measurement points
• 90,000 gallons of liquid nitrogen for
  cryo-pumping
• Independent potable water waste disposal plants
  with 2.5 miles of pipeline fire suppression
  system (tested!)
• 28 electrical transformers, 2 independent
  electrical distribution systems, 100 miles of
  fiber optic lines

Hi-Tech InfrastructureProduct (Data) Pipeline

• Wide Area Network (WAN) lines to campus through
  DOE our routers/security/etc. start at PNNL
• Three large Local Area Networks (LANs)
• General Computing (GC) principally
  science/engineering analysis on 50 computers
  plus WAN interface, security, web hosting,
  electronic document archiving/reproduction,
  digital A/V systems
• Control Data System (CDS) observatory central
  nervous system and machine diagnostics
• LIGO Data Analysis System (LDAS) production
  real-time data analysis and data shipping of 0.5
  Terabyte/day
• Flat-loaded 24/7 duty by 2002
• If any system at either site goes down, US GW
  effort is off-line

Product Pipeline Example LDAS at Hanford

• 4 Sun Enterprise 450 servers w/ 2-4 secondary
  servers
• 4-8 onsite user machines for visitors
• 15.5 Terabyte Disk Farm
• 100ea, 1-GHz-PC, Beowulf Cluster w/ Megapoint FFT
  Rating (28 Gflops)
• 1.5 Terabyte Tape Library System (Tape robot
  AIT tapes 2 tapes 24/7 at 6 MB/s)
• Gigabit 100BaseT Ethernet LAN
• R/T data-handling analysis software
• Major power/cooling requirements vibration source

Hi-Tech Support Laboratories Currently in
Operation

• Optics Lab
• Optics receiving, cleaning, assembly, balancing
  (class 100)
• High power IR laser work
• General optics experimental set up space
• Vacuum Prep Lab
• Cleaning, vacuum-baking residual gas
  certification of components (class 100)
• Clean Assembly Lab
• Handles all out-of-chamber assembly for in-vacuo
  interferometer components (class 100)
• Electronics Lab
• 1000 sq ft to measure, service detector, plant
  and collaboration set-ups

6
Hi-Tech Support Laboratories Currently in
Operation (continued)

• Mechanical Lab
• Set-ups that do not require class 100
  environments
• Vacuum components maintenance
• Remote labs in mid-stations and end-station
• Service, repairs and staging space used on
  as-needed basis
• All buildings housing clean laboratory space
  have special receiving/cleaning areas for
  materials transfer

7
Staging Building

• Provides facilities for integration of hardware
  upgrades once initial LIGO detectors are
  operational
• Separate science detector development chambers
  were down-sized from original LIGO concept but
  upgrade problem remained
• Minimizes down time of working detectors by
  pre-integration to optimize science goals
• High-bay area accommodates same hook-height as
  LVEA
• Machine shop (non-staffed)
• Separate work area for desks, computers, etc.
• Modifications will provide for materials handling
• Providing surge space during commissioning prior
  to completion of OSB East Bldg

8
Operations Support East Building

• Provides remainder of observatory
  office/laboratory space to take LIGO through next
  5-10 yrs
• 10,000 sq ft to expand functions in OSB West
  Building
• 4000 sq ft of lab space, including home for
  LDAS computing needs
• Includes auditorium and office space to
  accommodate collaboration and outreach work as
  well as resident staff and visitors
• Final element of facilities construction
