Working Groups

• Goals of this meeting
• Define role of working groups in LIST structure
• Determine number and character of working groups
• Define mode of operation of working groups
• E.g. subgroups, etc.
• Membership?
• Co-chairs?
• Selection of members
• Near-term schedule
• Steps to constitute groups
• First meetings

6
Working Groups Possible Approach

• Define broad working groups which span most
  scientific and technical areas
• Examples
• Sensitivity Sources
• Mission Architecture?
• Interferometry, Lasers Optics
• Disturbance Sensors Drag-free Control
• Science Operations
• In-flight calibration, data reduction and
  processing
• Calibration Test
• On-ground IT
• Integrated Modeling
• Permanent or core members are designated from
  both Europe and US
• Co-chairs from Europe and US
• Core members set agenda of working group, create
  subgroups for specific well-defined tasks
• Subgroups consist of scientists, engineers, other
  project personnel as appropriate

7
Working Groups Possible Approach (2)

• Purpose of working groups is twofold
• Support the LIST in carrying out its
  responsibility to make sound scientific
  recommendations for LISA
• Working groups report formally through their
  chair(s) to the LIST
• Support the Project by carrying out specific
  scientific and technical studies on topics of
  importance to LISA
• Advise project on various topics
• Sub-groups include Project personnel when
  appropriate to enhance information exchange
• One of the goals of the working groups is to
  promote exchange of information between engineers
  and scientists
• Note recent successful scientist/engineer
  workshop in US

8
Working Groups

• Questions
• Should working groups be joint, parallel,
  separate?
• How are core members supported?
• How are sub-group members supported?
• Who chooses working group chairs?

LIST List Near-Term Program

• Low-frequency LISA requirements - science goals
  WG 1 and WG 5
  Update by 10/01
• Slope, turnover, low-frequency limit, source
  backgrounds
• Minimum science requirements goals (
  Rationale)
• Number of sources of each type versus achieved
  performance (Kips LIGO paper as template?).
  Identify achievable science at each level
• Optimization of mission for given achieved
  performance
• Mission lifetime requirement minimum extended
