 * cleanness of the PSL room w.o. KOACH

 * Engineering run has been done on 6/8.
  * KOACH and AC operation need to be fixed.
   * will be discussed on the commissioning meeting on 6/11. (Kokeyama-san will summerize it)
  * RefCav might be better to be evacuated again for the temperature drift.
   * Nakano will check the data about the FSS.
  * We saw the alignment drift due to the temperature drift.
   * Short-term ASC would be worthful.
  * IOO manual is missing.		 === OMC, OMMT, OSTM ===
 * OMC commissioning is on going.
  * The OMC transmission is too small [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=9404]]
  * ugly cavity scan [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=9428]]
  * Beam profile of injection beam into the OMC looks fine [reported soon]
  * Still we are not sure it comes from the alignment issue. One of the OMC team (maybe Otabe-kun?) will come to Kamioka, and will investigate it. We wouldn't pull it out from the chamber this Wednesday, but we need to decide as soon as possible.
 * OSTM replacement
  * The modification parts were delivered and checked in Mitaka. Takahashi-san will come to Kamioka next week for the OSEM check.
=== Niigata ===
 * Double demodulation
  * First Koyama-kun will discuss with Michimura-san, and then start the experiment in Kamioka.
 * Scattering measurement
  * Tsugai-kun and Murakami-kun is working to improve the S/N ratio of the measurement, and they will have a poster at F2F meeting.

=== PSL ===
 * Laser POW MON (IMC IN) is fixed and working
  *[[klog|http://klog.icrr.u-tokyo.ac.jp/osl/?r=9365]]
 * Beam shutter driver is modified and works well in PSL
  *[[http://klog.icrr.u-tokyo.ac.jp/osl/?r=8993]]
  * We need to check the spectrum of IMC TRANS, REFL, and an error signal. And more?
 * MZM was removed.
  *[[http://klog.icrr.u-tokyo.ac.jp/osl/?r=8957]]
 * MZM paper is on-going (2nd-draft was circulated)
  * 3rd-draft will be circulated before CPC circulation
  * Izumi-san, Michimura-san, and Yamakoh will have a meeting about it in Tokyo before 3rd-circulation.
 
=== IMC ===
 * measured the asc sensmat with the new position of IP1 isn't good.
  *[[http://klog.icrr.u-tokyo.ac.jp/osl/?r=8982]]
  * The beam size on each IP need to be the same. We need to re-design.
  * However, still it would be good to implement the short-term IP-ASC. It can compensate for the IP drift.
  * Added on the ToDos for O3
 * HPBD thermometer ongoing
  * Miyo-kun is testing the read-out circuit.
  * On Wednesday, we will have a data on the DGS channel.

=== OMC, OMMT, OSTM ===
 * OSTM replacement is on-going
  * The mirror will be changed to a thicker one. Matteo is negotiating with a company.
  * TAMA-IMC will be used for OSTM suspension, and Takahashi-san is working on it.
  * Replacement is scheduled on September.

=== Others ===
 * IFI chamber optics meeting on 6/10
 * IFO-REFL table power adjustment system needs to be designed. MIF will work on it.

== Visitor ==
 * Koyama-kun and Prof Suzuki (Niigata) will visit Kamioka (6/11)
 * GG left last week, and come back on end of this month

== Next meeting ==
 * The meeting schedule will be changed. Nakano will arrange the new candidate.		 == Meeting schedule ==
