Introduction to Cryogenics for Research Infrastructures (training course, on-site)
David Rabanus
(Course no. 3682026 in the training programme 2026 of Forschungszentrum Jülich)
This course takes place on-site at JSC. Online participation is not possible. The course will be held in English.
Course Content:
Cryogenics – the science of extremely low temperatures – serves as the invisible backbone of modern high-level research. Without the ability to cool systems down to near absolute zero, many of today’s scientific breakthroughs would be impossible. From enabling superconductivity in particle accelerators and fusion reactors to stabilising qubits in quantum computers, cryogenics is the "enabling technology" behind many large-scale research infrastructures.
This course explores the fundamental physics of cryogenics, demonstrates the practical skills required to operate 4K systems and outlines important safety guidelines. In practical hands-on exercises, participants will gain first experience in assembling and operating cryogenic systems.
- Basics of low-temperature physics and cryogenics (gases, liquefaction, phase diagrams)
- Turn-key cryostats and cryocoolers up to 4K: components, safe operation, daily checks
- Temperature sensors, basic measurements, and data logging
- Vacuum fundamentals: pumps, gauges, leaks, simple troubleshooting
- Safety rules, hazards (asphyxiation, cold burns), personal protection
- Hands-on: assembling a basic setup, first cooldown, recognising common failures
