New 63U ATCA rack: thermal performances and integration challenge

To save the space in the underground counting rooms during the ATLAS phase II upgrades, a
project dedicated to the study of the impact of installing taller racks within the counting rooms
was launched, analysing its cooling performance and the impact on the cooling infrastructures.
A new 63U prototype rack equipped with three ATCA shelves, with open-bottom to top airflow,
high-power dissipating load blades, three new prototype 2U heat exchangers and various sensors
was installed in a lab. The impact on the cooling performance of stacking three ATCA crates
within a rack was checked, along with other critical aspects.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
