Michimura thinks we should ask for comments from collaboration at some point. * Comments from FSC members are also welcomed at any point. Michimura can give feedback to the TF. * White paper writing * To make it easier to maintain, * Start planning in the FSC meetings, allocating people to write the section * Let's have a workshop sometime in Aug? to focus on white paper writing. * Let's aim for 2024 version of the FSC white paper by Dec 2024 F2F. * Authorship and PRD applications will start in Feb 2025. * How often we should update the science case calculations? * It would be nice if we can automate the basic science case studies like event rates, parameter estimation etc. so that people can do science case studies quickly. * We can have theorists do the calculation when we have a "big" update in the proposed sensitivity curves. * It would also be nice if theorists can provide some requirements to do specific science cases. * '''A/I''' Fix the dates for the white paper writing workshop [Michimura] * '''A/I''' Call for new FWG members [Michimura] * '''A/I''' Check with Haino-san et al. about the difference between Overleaf and JGWdoc version of FPC white paper [Michimura] * '''A/I''' Report what was discussed in JGWC and 10 yr TF at the next FSC meeting [Michimura] == Agenda == * New member list * Yuta Michimura (Chair) * Sadakazu Haino, Atsushi Nishizawa, Kentaro Somiya (Co-chairs) * Masaki Ando, Hong-Bo Jin, Ray-Kuang Lee, Matteo Leonardi, Ettore Majorana, Quynh Lan Nguyen, Surojit Saha, Lijing Shao, Shalika Singh, Haoyu Wang, Kazuhiro Yamamoto, Takaaki Yokozawa * Goal of FSC * FSC's goal is to make a suggestion of a concrete plan for KAGRA+ and beyond, based on both science and available technologies. * Scope of FSC * White paper writing * Organizing Project R&D and Advanced R&D * Coordination of Future Working Group Open Meetings * Responsible for future discussions within KAGRA * Responsible for future discussions in JGWC, CRC meetings etc. * Responsible for discussions of 2.5-3Gs in LVK meetings, IGWN etc. * Organization * Future Planning Committee (or white paper writing team): Dissolved. Entire FSC will take care of white paper writing * Project R&D Committee (PRDC) Chair: Kentaro Somiya * Advanced R&D: R&D that are not PRD yet * Future Working Group (FWG): Discuss new ideas and techniques for future gravitational-wave detectors (not only for KAGRA). * Recently, chair is also joining 10 yr Task Force under EO and responsible for Instrument Science session in LVK meetings. * [[https://dac.icrr.u-tokyo.ac.jp/KAGRA/EO/10yr%20task%20force|10 yr Task Force]] * Project R&D * How was the applications? * I think we should relax the criteria for being PRD, and approve almost all the applications (after some revisions if necessary). * PRD is a good way to help young scientists start contributing to KAGRA * There are also critisms about not contributing to KAGRA directly * Updating white paper * Science part can be integrated into LVK Observational Science White Paper, and KAGRA-relevant topics can be extracted from this. We can also include KAGRA-specific science to the LVK Observational Science White Paper (e.g. B-L dark matter is already included) * There is no LVK Instrument Science White Paper yet (only LSC), and KAGRA-specific one may be necessary. * Instrument science part could be updated annually. Just list up new technologies or updates on technology developments. We could also update the matrix to score each technology. [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=9590|KAGRA FPC White Paper - Part I JGW-M1909590]] * We could propose new KAGRA+ sensitivity curves and update BBH/BNS event rates, BBH/BNS sky localization, inclination/distance estimation. * How about having a FSC white paper writing workshop to review new technologies and updates on technology developments over the last 5 years, and write them as a white paper 2024. * Any suggestion on when and where? * Future Working Group 4th Open Meeting * How about having it in-person with F2F Dec 2024? * Report from 10yr Task Force * Any other discussions?
