Introduction by Aso

Why FPC is proposed ?
Purpose/Scope of FPC
Steps to start FPC

Summary of the past upgrade studies by Michimura

Extensive studies have already been carried out
Several options were compared
- High frequency optimized plan seems better
Candidates for short term upgrade (cheap, quick) and longer term upgrade (larger change and more expensive) were discussed

Contributed talks by various people

100kg sapphire (Hirose)
Frequency dependent squeezing (Lee)
Newtonian noise measurement (Shimoda)
TAMA300 filter cavity (Zhao, Wu)
EPR entanglement (Somiya)
Engineering management (Aso)

Discussion

What should be included in the white paper

Scientific motivation
Survey of the current technologies
- Cheap, Expensive
- Ready, Not ready
Limits of the current facility
Trade-off studies
Two plans
- Near term upgrade plan
- Longer term upgrade plan
Back up plans
R&Ds to be done
- Budget for R&D
Budget estimate
Project execution plan

Schedule for the white paper

Work in progress draft to be presented @ KIW in Feb 2019
- Get feedbacks from Virgo people
First draft to be circulated @ April 2019 F2F
Final version to be put for approval @ Aug 2019 F2F

How to proceed the discussion ?

Make a skelton of the white paper first
Dig deeper into each item with sub-groups

Other discussion

Definitions of short term and longer term upgrades
- Short term: after O4 (~ in 5 years)
- Longer term: after O5-6 ? ~ in 10 years
- This should be discussed in FPC
How to get funding should be discussed with relevant people (ICRR, senior people in collaborating countries, etc) in parallel with the white paper writing.
Need to keep ICRR in the circle.
Review (external/internal) of the white paper may be necessary before submitting to the KSC and EO for approval.
The white paper should be updated with changing environment
How RDC should select KAGRA project R&Ds before the white paper is finalized ?
- RDC may be able to make interim approvals
  - These interim KAGRA project R&Ds should be checked against the white paper once it is ready
- Should be discussed more in the KSC session.
