The power fluctuations on B8 and B1p are due to the etalon effect.
The reason is that the WI cryo trap was closed so we need to wait for the cooling of the WI mirror (see figure 2).
We will be at regime in 1/2 days
I ve changed the set point of WI etalon to be in the minimum of B1p and closer to the actual position, but still close to the former one.
New setpoint is 20.48
the etalon down condition for the NI and WI have been set back
