Evan, Yuta, Kiwamu,

Commissioning of the dithering system is underway.

A summary of the red commissioning from this morning:

• We locked the PRMI with the 1f signals and noticed that the lock was fragile.
• Then we realized that the demodulation phase of REFLAIR_RF45 was set back to 133 deg which should be 144.6 deg (see alog 9930) to make the two loops decoupled.
  • This was missing in the guardian
• Once we confirmed that the PRMI can stay locked, we moved on to PRX.
• We started commissioning the dither system (ADS = Alignment Dither System).
  • This is still an ongoing task.
