-== Q&A from PAB ==
||No.||Question from PAB||Answer||
|| || || ||
||1.||What are KAGRA managements’ thoughts regarding the impending departure of KEK from the MOU regarding KAGRA support in the area of cryogenics? Are there other areas of common areas of synergistic collaboration going forward beyond KAGRA construction and into operations?||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10182|o]]||
||2.||In KAGRA”s opinion, what constitutes an acceptable “physics result” in O3 that will ensure KAGRA’s continued funding by MEXT?||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10183|o]]||
||3.||What tasks will be assigned to (246) people spending time the observatory during science operations? How long will individual visitors be at the site? How will they be trained? How many will be contributing to keeping the detector in operation at its optimum operating point? Will they continue to work on their problems once they return to their home institutions?||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10198|o]]||
||4.||With regard to safety concerns: We would like to know how much time/budget is involved in realizing the various remaining safety measures: specifically:<<BR>>   -    laser safety -- there should be a card-access based system to only allow laser-safety qualified staff to enter areas of high power laser hazards. Related: an automatic shutdown remains something that should be required and installed. The current manual safety shutdown is not sufficient in case of a serious accident.<<BR>>   -    air supply ducts -- ensuring adequate air supply in the event of a cave-in, especially at the X-end.||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10187|o]]||
||5.||What does the risk register from 2015 look like? Is it possible for KAGRA to share this with the PAB tomorrow?||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10176|o]]||
||6.||Can KAGRA show their projections of the transfer function and attenuation of ground motion for Type-A VIS that has 3 stages mechanically shorted? Specifically, is there an h[f] curve that characterizes this configuration?||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10179|o]]||
||7.||What are KAGRA’s plans for on-line data analysis plans? How many real-time trigger generators will be running? Which ones are they?||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10191|o]]||
||8.||What is the decision-making process within KAGRA organization? The PAB found it peculiar that a number of presenters showed “personal opinions” as part of their presentations, e.g., modified schedules etc.||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10184|o]]||
||9.||How does KAGRA approach public outreach, especially to the stakeholders (funding agencies and the general public). The PAB considers this important as KAGRA contemplates seeking additional funding.||[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10185|o]]||
