Short Courses

Monday, the 19th of July 2010

 

Three short courses will be held preceding the ICEC 23 – ICMC 2010 (Short Course Participant do not have to be a Conference Participant (Student Participant)):

Basic Thermodynamical Cycles for Helium Refrigeration (full-day course by Guy GISTAU BAGUER)

This short course is intended to make beginners understand cryogenic refrigeration thermodynamical cycles; it is not intended to teach how to design cryogenic systems.
The main guideline of the course is the natural thinking path that one follows when studying a problem. Difficulty and complexity go increasing with progression in the topic.
Theory is limited to what is necessary to understand the processes that are introduced and discussed in the course. It is not intended to teach Thermodynamics. Only a few equations are displayed. The goal is to make people "feel" the operation of machines; for that, in the basic cycle presentations about refrigeration, emphasis is put on energy circulation in the systems.
The course is given through "animated" Microsoft PowerPoint® and Excel® presentations. Here, the goal is to make people follow explanations in a comfortable way: the presentation displays information at the same rate as oral explanations, as if the orator were drawing on a black board (see Advances in Cryogenic Engineering, Vol. 49A, CEC 2003, Anchorage, pages: 101 to 110). The Excel® animated presentations allow making "live" calculations on examples that are significant; for example, the way in which the exchange diagram of a heat exchanger is modified according to the operating conditions.

Cryogenic Safety (full-day course by Friedrich HAUG, Goran PERINIC, John WEISEND)

Knowledge in Cryogenic Safety is vital for personnel handling cryogens and for the engineer and technician designing and constructing cryogenic equipment and systems. The properties of cryogenic fluids and of materials at cryogenic temperatures create unique hazards. This course covers a variety of topics and we start with an introduction to refrigeration, storage and transfer equipment. Then the physical properties and the potential hazards of cryogens are reviewed. Risks during handling are presented and, advice for the practitioner given. Low temperature characteristics of structure material, guidelines and rules for the design of vessels and their protection are presented. Particular emphasis is given to  pressure safety and oxygen deficiency hazard safety. Cryogenic systems and process control must be conceived to cope with a number of operation faults. In severe cases of accidental coolant loss, detection systems must produce alarms which result in emergency responses. Examples comprise underground installations in high energy physics laboratories where high safety standards are requested. Prevention, knowledge and training are the keys to minimize risks to personnel. This class is suitable for students and professionals working in all areas of cryogenics including large and small scale systems. 


Superconductors for Applications (full-day course by Bartek GŁOWACKI)


This short course is intended to make people already working in the field of superconductivity, young engineers and also final year undergraduates or first-year graduate students, understand importance of the superconducting materials in cryogenic applications.
The course will cover methods of tailoring superconducting materials through explorations and solutions to fundamental problems presented for particular applications. It will address and explain the physics behind the properties of the superconducting materials for a range of applications, such as: thin film technology for electronic detectors, devices, and sensors, design and fabrication of advanced conductors for machines and large energy devices, e.g. motors, cables, flywheel, fault current limiters, MRI, and fusion,
Division of the presented course material into chapters and sections will be similar to that in the DVD “Lectures on Superconductivity”: Fundamentals, Materials, Electronics, Applications http://www.msm.cam.ac.uk/ascg/lectures/

Introduction to Cryostat Design (by John WEISEND).

Cryostats are the fundamental building blocks of cryogenic systems. Their basic function is to keep equipment and materials at the desired cryogenic temperature. Cryostats may contain a wide variety of equipment, for example: superconducting magnets, telescopes, detector arrays, beam targets and material test assemblies. In addition, many cryostats have unique requirements, such as the need for particle beam or optical access, severe alignment or vibration tolerances, extremely low heat leak or the capability for space launch. Despite this variation, all cryostats have common design issues and solutions. It is the goal of this short course to survey the fundamental aspects of cryostat design and illustrate solutions by using existing designs. The class will include practical design techniques and data as well as references to more detailed information. Students, new cryostat designers and researchers who use cryostats in their work will all benefits from this class.
