23 November >>10am Cryocoolers - Lecture by the Professor De Waele ( Technische Universiteit Eindhoven)
Thursday 23rd November 2017 - 10am to 12am
Institut Néel - CNRS Grenoble
25, av. des Martyrs
Prof.Dr. Alphons (Fons) de Waele is a renowned expert in the field of cryogenics. After a PhD on Josephson effect and thermoelectric effects in superconductors, he joined the Eindhoven University of Technology, where he worked successively on dilution refrigerators, cryocoolers, in particular pulse-tube coolers down to 1.2 K, and thermo-acoustics refrigeration.
As a co-organizer and teacher of the European Cryoschool for PhD students, he is well known for his lectures on thermodynamics of open systems and cryogenic technologies.
Since his retirement, he is an active advisor in the field of cryogenic technology in particular related to superconducting motors.
These lectures are open to everybody interested. They are recognized by two doctoral training programs (EDPhys and IMEP2). Lectures will be held at Institut Néel, CNRS, Grenoble.
- The operation principles of AC coolers like Stirling coolers, pulse-tube coolers, GM coolers are discussed from the perspective of thermodynamics and gas dynamics
- The Joule-Thomson liquefiers and coolers treated mainly using hT-diagrams. The concept of pinch points will be introduced
- The working principle of the Collins liquefier and the reverse Brayton cooler
- Based on scatter diagrams some general properties and challenges of cryocoolers will be addressed
