Yesterday evening, for an unkown reason, the current of the pumping diodes suddently decreased (figure 1). 
This morning we went in EER, we had 27.8 A for diode 1 and 27.6 for diode 2. We brought the current back to 29 A and got the system as it was on saturday (figure 2). 
We waited for everything to thermalized and we went to realign the PMC, shift and tilt (figure 3)
