| * Michelson fringe could be seen yesterday! * Damping of ETMs is still not enough. * Needs damping for ETMX. |
* Michelson fringe was seen on DC and RF, but still mirror motion is too large. * Needs more work for damping for both ETMs, L2P of BS. |

| * RT model: Yamamoto * BS model was splitted into 4kHz and 16kHz. No glitch was seen since then. * Found how to start/stop Dolphin without killing RT models connected to Dolphin. * Needs preparation to send signals to ETMs. |
* DGS: * IO chassis of k1ioo was disconnected somehow. It is being checked now. |

| * CAL: Yamamoto, Yokozawa * RT calibration model moved to using LSC. * DAQ * Recoding minute_raw of k1fw0 moved to SSD at k1tw0. * Door closing started. It will be done Wednesday or Thursday. * Frange exchange is done. |
* DAQ: * Recoding minute_raw of k1fw1 moved to SSD at k1tw1. All fw0,1 tw0,1 are working well without any gap on data. |

Minute of KAGRA commissioning meeting
- Date: 2018/4/17 11AM~12PM
- Attendance: Miyakawa, Kokeyama, Aso, Uchiyama, Miyoki, Akutsu
- eZuce: Yamamoto, Suzuki, Shoda
1. Report of work of the last week and plan of work
- VAC:
- Door was closed and pump down started. One large leak was found and it is being searched where it is.
- IFO, ETMs: Enomono, Ushiba
- Michelson fringe was seen on DC and RF, but still mirror motion is too large.
- Needs more work for damping for both ETMs, L2P of BS.
- DGS:
- IO chassis of k1ioo was disconnected somehow. It is being checked now.
- DAQ:
- Recoding minute_raw of k1fw1 moved to SSD at k1tw1. All fw0,1 tw0,1 are working well without any gap on data.
2. Operation
- Noise injection needs some preparations for speakers.
- Schnupp asymmetry need some preparations.
- Other plan seems to be ready.
- CBC will perform an online analysis.
3. Tasks or discussions
Selection of full channel -> DGS Yamamoto
Selection of science channel -> Commissioning Izumi
- Screens at control room
- Sensitivity.
- PEM.
- Needs laser safety information.
GW alert: online alert in the control room might be prepared. -> Togoshi
Others
- Phase 1 summarize should talk wide range view.
- Type A has double stable point.
- Monitor for water level, and vacuum gage for weekend should be implemented.
- Patrol light should be implemented soon, even manual one.
- Next meeting: 4/10
