8 Small Science - Big Science 14-April-09 NEON Workshop 8

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 9

10 Newton s Theory instantaneous action at a distance G µν = 8πΤ µν Einstein s Theory information carried by gravitational radiation at the speed of light 14-April-09 NEON Workshop 10

11 The Concept free masses h = strain amplitude of grav. waves h = ΔL/L ~ L = 4 km ΔL ~ m Laser Interferometer laser 14-April-09 NEON Workshop 11

12 The Concept - Interferometry Laser used to measure relative lengths of two orthogonal arms causing the interference pattern to change at the photodiode Arms in LIGO are 4km Measure difference in length to one part in or meters As a wave passes, the arm lengths change in different ways. 14-April-09 NEON Workshop 12

13 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 13

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 14-April-09 NEON Workshop 14

28 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 28

29 LIGO Scientific Collaboration Bylaws 14-April-09 NEON Workshop 29

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!! 14-April-09 NEON Workshop 30
