The aim of the course is to provide participants with an understanding of basic principles in cryogenics being of importance for the design and construction of cryogenic equipment.

After the course the participants will have an insight in:

• Refrigeration, what makes processes work to refrigerate and liquefy helium and other fluids and what is the thermodynamics behind
   
• Cryogenic fluids, what are the fluids and their properties, how cryogenics fluids behave, how to store them
   
• Cryogenic equipment, what kind of equipment is required in cryogenics and how do they work, how are they designedm how are cryostats designed
   
• Low temperature properties of materials, how do the materials behave at low temperatures and what are the particularities one has to pay attention to for the design of equipment
   
• Insulation techniques, how to provide for the unusual insulation in cryogenics and how to produce vacuum needed
   
• ESS, what is the new Scandinavian based European research laboratorym how will it look like and what is the role in cryogenics

CONTENTS

The course gives an introduction to the interdisciplinary field of low temperature technology (cryogenics). Basics in thermodynamics of refrigeration and the processes applied are introduced together with the properties of cryogenic fluids. Emphasis is on fundamental engineering technologies of cryogenic equipment which comprises properties of materials at low temperature, insulation techniques and design. Low temperature technology is a comparatively young engineering branch with future potential and is indispensible for accelerator and space technology, some medical technologies, industry, superconductivity and basic research.

LECTURER

Dr. Friedrich Haug studied Mechanical Engineering at the University of Applied Science at Ulm and at the University of Stuttgart, Germany. He did research at the Joint Research Centre of the European Commission in Ispra, Italy from 1981-1984 and at the Los Almos National Laboratory, USA, from 1984-1986. In 1986 he joined CERN where he worked on cryogenics for detectors and large scale test facilities. He participated in the design and commissioning of the ATLAS detector cryogenics and held a position as a deputy group leader for Cryogenics for Experiments.
