| * Tuning of ETMY is still going on. ETMY yaw motion is still too large. * Trying feedforward, but not so effective. * BF is also being tuned. * Alignment to REFL port was done. * Testing full LSC model started. It will be run at k1imc. * RT model seems to have additional time delay ~61usec to 200usec. Unknown. |
* Tuning of ETMY is still going on. ETMY yaw motion is still large. * Beam will be checked every night. |

| * Beam will be checked every night. * CAL group also requires iMC in the night. * Some of SUS, specially IMMT showed jumps several times, probably due to duct connection. * One of the flat ribbon cables to picomotor was cut and broken between the connector and cable, probably due to the duct connection. |
* MIF: * LSC full model has been implemented in k1imc. |

| === Feed back to BS for MICH === * Experimental side: no matter. * Data analysis side: * LSC model(Michimura, Izumi) * Full model will be implemented at k1imc. * CAL model location? at the same k1imc, or k1test with Dolphin connection. |

Minute of KAGRA commissioning meeting
- Date: 2018/3/20 11AM~12PM
- Attendance: Miyakawa, Aso, Izumi
- eZuce:
1. Report of work of the last week and plan of work
- Alignment, ETMY: Izumi
- Tuning of ETMY is still going on. ETMY yaw motion is still large.
- Beam will be checked every night.
- MIF:
- LSC full model has been implemented in k1imc.
- CAL:
- Started using IMC as training of calibration.
- X end PD will be removed and Baffle PD will be located instead. Changing PD will be done around 3/26.
- Cryo:
- Current temperature is 18K.
2. Schedule of ETMX installtion
- See the schedule at the commissioning top page.
3. Tasks or discussions
- CAL model location? at the same k1imc, or k1test with Dolphin connection.
Selection of storing DAQ channel -> DGS, before phase 1
- Check the total amount.
Screens at control room -> who, when?
- Needs laser safety information.
GW alert: online alert in the control room might be prepared. -> Togoshi
4. Phase2
Others
- Frequency noise can be measured by middle lock. Large intensity noise can be a problem.
- Next meeting: 3/27
