In the accelerator, we are archiving the temperature PV. Taking a quick look
here in the last year time span, their usual and highest temperature is close
to 50°C. I could see a single one operating close to 54°C. In the beamlines,
the situation is different, we aren't archiving the temperature yet. That's an
ongoing task.

According to the specs (and the status parameter), supposedly not. But as Mark
S. mentioned in his message, they noticed that a slight increase in temperature
above 50°C has shown to be a problem for them. Maybe it is indeed a consequence
of heating.

Thanks.
