Collaborating on Mega Science Facilities
Barry Barish Caltech
NEON Workshop Tucson 13-April-09
LIGO Livingston, Louisiana
14-April-09 NEON Workshop 2
Big Science at NSF? Advancements in science
» Individual Investigators
– The heart of the NSF program
» Large Infrastructure Support – Polar Program
– Complex management – International treaty – International participation
» Large Science Projects – LIGO – Large Collaboration
14-April-09 NEON Workshop 4
ALMA Project
Argentina
Atacama Large Millimeter/submillimeter Array of up to 80 high-precision antennas
14-April-09 NEON Workshop 5
Ice Cube Project Neutrino Astrophysics – Investigating
astrophysical sources emitting ultra high energy neutrinos
South Pole
14-April-09 NEON Workshop 9
Large-scale Science Project
Must mix small science culture with big science culture » Conception & Design – small science
leads » Planning – big science leads » Execution – big science leads
– Solve technical problems – small science crucial
» Transition to science usage – transition towards small science
14-April-09 NEON Workshop 10
Newton’s Theory “instantaneous action at a
distance”
Einstein’s Theory information carried
by gravitational radiation at the speed
of light
Gµν= 8πΤµν

The Concept
Laser Interferometer
free masses
h = strain amplitude of grav. waves h = ΔL/L ~ 10-21
L = 4 km ΔL ~ 10-18 m
14-April-09 NEON Workshop 12
The Concept - Interferometry
Laser used to measure relative lengths of two orthogonal arms
As a wave passes, the arm lengths change in different ways….
…causing the interference pattern to
change at the photodiode
Arms in LIGO are 4km Measure difference in
length to one part in 1021 or 10-18 meters

LIGO Project phases Define Science Goals (community support) Define Concept - R&D Determine baseline (science requirements) Design – stage I concept or reference Design – stage II engineering Baseline the design (cost, schedule, PM) Industrialization Performance - earn value, quality Integration
14-April-09 NEON Workshop 14
Work Breakdown Structure (WBS) Break down all work to complete the project
» Include all physical deliverables, subsystems » Include R&D, design, prototyping, fabrication,
assembly, installation, acceptance testing leading to a deliverable product
» Include administration, system engineering, purchasing, reporting not directly related to deliverable products
» Break work down to 5-8 levels from top when mature
Organize work to support deliverables
If work will involve major contracts, represent them in the WBS
Write out a WBS dictionary and maintain it

Why a Scientific Collaboration? All scientists participate on equal
footing in the science » LIGO Lab scientists and University
scientists all do science through the collaboration
Provide enabling and collaborating mechanisms to carry out research
Governance is well documented, determined by the collaboration, updated periodically
14-April-09 NEON Workshop 30
LIGO : Lessons Learned Large collaborations require some level
of organization and organizational principles
Individuality can and should thrive within large science research
The scientists should organize how they do their research, have access to data, present results, etc
One size does not fit all !!
