Low power for North ALS

Lately the monitoring channel for the North ALS has shown some degradation; tonight it went below the threshold which triggers the fault state twice, and the rising wind is not helping. It also shows a very slow oscillation around 13 mHz.

I stopped the lock acquisition at LOCKED_ARMS_IR.

This morning we went to the DAQ room and we re-positioned the fiber that goes to the North Arm until we recovered enough power in the terminal building. The system should be working now.
