We realized that the increase of temperature of MG7 and MG9 during run 600 (alpha calibration) was due to the fact that a loop of the cooling system was not working since the pipes were not properly connected. We re-connected them and switched on the low voltage without making the vacuum just to monitor the evolution of the temperature.
Temperature after 10 minutes from the LV switch on:
MG1 X = 20 deg; MG1 Y = 18 deg
MG3 X = 20 deg; MG3 Y = 19 deg
MG4 X = 19 deg; MG4 Y = 17 deg
MG5 X = 21 deg; MG5 Y = 19 deg
MG7 X = 20 deg; MG7 Y = 18 deg
MG2 X = 20 deg; MG2 Y = 19 deg
MG11 X = 20 deg; MG11 Y = 19 deg
MG9 X = 56 deg; MG9 Y = 26 deg --> We believe that we cannot really trust these values, they didn't change since yesterday evening and the board is cold (we touched it)
MM1 X = 18 deg; MM1 Y = 18 deg
MM2 X = 18 deg; MM2 Y = 18 deg
MM3 X = 18 deg; MM3 Y = 18 deg
MM4 X = 19 deg; MM4 Y = 18 deg |
