| * Kokeyama-san reported that the orientation of the mirror was incorrent in MISALIGNED state: the beam was not going into the beam dump and the beam was not going onto the PSD (see klog entry [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=11260|11260]] and links thereir): * Against our expectations the beam goes ontt the PSD in ALIGNED state. * In such a state in order to misalign the mirror actuation was applied to test channels BF yaw, IM yaw and IM pitch and the output of the oplev DC control were frozen. * I found a new set of suitable offsets.

Type-Bp
Past week report
Kokeyama-san reported that the orientation of the mirror was incorrent in MISALIGNED state: the beam was not going into the beam dump and the beam was not going onto the PSD (see klog entry 11260 and links thereir):
- Against our expectations the beam goes ontt the PSD in ALIGNED state.
- In such a state in order to misalign the mirror actuation was applied to test channels BF yaw, IM yaw and IM pitch and the output of the oplev DC control were frozen.
- I found a new set of suitable offsets. See klog entry .
- Fortunatelly in the new appropriate orientation the IM is closer to the SAFE, so nothing is expected to be touching.
- Yamamoto-kun and I created a snapshot file for the MISALIGNED state usind the SDF and updated the new values.
