DRFPMI (RSE)(42 Mpc)

PRFPMI(27 Mpc)

FPMI(9.5 / 16 Mpc)

ALS (green lock) ◎ ○ ×(better to have)

f3 AM (MZI *) ◎ ○ ×

Extra locking simulation × ◎ ×

SRC ASC ◎ × ×

SRM ◎ ○(Blank or move OMMT)

○(Blank or move OMMT)

OMC △ △ △

Comment SRC ASC might be tough f1 will be 1/10, no SRC mode cleaning

PRM: tilt or blank or move IMMTNo PRC jitter attenuation

◎: Necessary for locking○: Can be omitted with extra work△: Can be omitted with sensitivity degradation×: Not necessary

* AM generation with 45 deg tilted EOM is not possible with wedged EOM


Noise Curves

5

Various possibilities of KAGRA's sensitivity

Enomoto and Michimura made 3 noise curves of KAGRA with BNS range of(1.3, 9.6, 42)Mpc. We interpolate these curves to obtain noise curves for other ranges. For LIGO/Virgo, LIGO: 120Mpc, Virgo 60Mpc (taken from arXiv:1304.0670v6)

Outline of the schedule

• Installation will be completed by the end of March 2019.

• Commissioning will start from September 2018 along with installation works.

• Commissioning of the first full interferometer configuration (FPMI) will start from March

2019. After then, we start DRFPMI or FPMI, depending on results of three checking points

planned on the end of September, December and March.

Data transfer rehearsal (test with L/V); possible schedule

• DMG & DAS are planning DTRs with dummy data before O3 starting.

KSC is in charge of scheduling and so on.

• DTRs shown on the bottom schedule will be using live KAGRA data.

DTRs may take a week or so.

DTR DTR DTR DTR11

Summary

• In the spring of 2019, we expect to complete the construction phase and move on to the commissioning phase. KAGRA plans to join O3 in the fall of 2019.
