| * ITMY: L was excited but TM actuator did not work. It will be checked today. * Type B: ezca commands did not work by some environmental issue, probably related to python compatibility. Mark found some way to fix the issue. It will be documented. |
* ETMX: Oplev mirror at IM was fixed. * ETMX: Opened hatch and checked the cable. Coupling at tower part still exists. It could be cable swapping. * ITMY: Accelerometer was fixed. * ITMY: IM actuator did not work. MN will be used for hierarchy control. * TM actuator had a problem on the circuit. Mechanically it seems to be OK. * VAC: Cleaning at ETMX is going on. * Maintenance was done. * Replaced k1als0 and k1lsc0. * Replaced HDD of k1nfs0. |
