| * 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. |

| * 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. |
* cleanness of the PSL room w.o. KOACH *[[http://klog.icrr.u-tokyo.ac.jp/osl/?r=9365]] |

| * 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. |
* IMC alignment script *[[http://klog.icrr.u-tokyo.ac.jp/osl/?r=9374]] * IMC error signal investigation *[[http://klog.icrr.u-tokyo.ac.jp/osl/?r=9364]] |

| * 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. |
* 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]] |
