Enseignement académique : Introduction to cryogenic Engineering

Cryogenic engineering is one of the key technologies at CERN. It is widely used in research and has many applications in industry and last but not least in medicine.

In research cryogenic engineering and its applications are omnipresent from the smallest laboratories to fusion reactors, huge detectors and accelerators. With the termination of the LHC, CERN will in fact become the world’s largest cryogenic installation.

This series of talks intends to introduce the non-cryogenist to the basic principles and challenges of cryogenic engineering and its applications. The course will also provide a basis for practical application as well as for further learning.

Glaciers are an integrated part of the high altitudes and the high latitudes of our planet. They are sensitive to temperature and moisture changes and adjust their mass balances accordingly. By doing so they interact with their substratum, the geological basement and they produce characteristic imprints of their presence, their variability and their disappearance. In glacial geology and paleoglaciology such imprints of former glaciers are carefully recorded, mapped and, hopefully, dated in order to obtain amplitude and periodicity records of their changes - as forced by changing climate, as we believe. In the upcoming lectures three aspects will be discussed:

1. the last glaciation in the Swiss Alps. A reconstruction is shown based on fieldwork both in the mountains and in the foreland within a regional chronology. The reconstruction of the Last Glacial Maximum ice cover in the Alps points to unknown paleocirculation patterns with Europe-wide implications.
2. the glacial record of the past 10 000 years. What rates-of-change in the climate pattern can be seen in glacier oscillations?
3. the far-away record of Antarctica is discussed in the controversy of a stable or unstable East Antarctic Ice Sheet.
