Figure 6.8: Cooling overview of a complete layer with active cooling. One can see that some
MCMs have a worse cooling than other MCMs. This is caused by a bad thermal coupling
between the MCMs and the cooling plates glued on top. As long as only a few
MCMs are affected no further action is required since the MCMs get sufficiently cooled
by the thermal coupling between the MCM and the readout board and by air cooling.
The readout chamber in the last stack (MCM column 60 – 75) was switched off. The
MCMs without a score value in the other stacks had a non-working temperature sensor
during this measurement and were automatically excluded. Figure 6.9 shows a
second measurement of the same layer.

Figure 6.9: Cooling overview of a complete layer with active cooling. The cooling line for the
MCMs in column 11 was blocked manually. The affected MCMs are clearly identifiable
as uncooled. If such an observation is done after the installation of a layer the problem
has to be fixed. Figure 6.8 shows a different plot of the same layer.
