[Ushiba, Hirata, Tanaka, Miyoki]

After the recovery of the IMC LSC ASC control, ushiba-kun checked the infkuence of the cable touch for the STM2 on the IMMT1/2 trans and pop forward etc.

According to Ushiba-kun opinion, the alignment of the STM2 seemed to be sensitive to the weight load of the cables, not the trembling of the cables themselves. When he lifted up the cables, the STM2 alignment moved temporally, but came bacck to the original position even after stopping to lift up. This implies that we can keep these cables if we can properly fix them on the optical table of the pole. However, it seemed to be quite difficult to perform such thing without mialignment of the STM2 mirror. So we decided that we cut these cables below the pin connections.

While, not so remarkable influence of the cable touch on the STM1 was observed. This is maybe because the a part of cables were winding on the optical table and their weight seemed not to pull the STM1, then they fell to the bottom of the vacuum chamber. So we decided to fix the cables by aluminum clamps on the optical table with a kapton sheet for protection.
