Course detail

Cryogenics

FSI-TK0Acad. year: 2026/2027

Basics of low temperature physics and cryogenics.

Language of instruction

Czech

Number of ECTS credits

3

Mode of study

Not applicable.

Entry knowledge

Basic course of physics.

Rules for evaluation and completion of the course

When awarding the course credit, attendance at lectures and laboratory exercises is taken into account. To obtain the credit, students must attend at least 50% of the scheduled lectures and exercises. It is recommended to complete all teaching blocks due to their interconnection. In case of absence from theoretical classes, the student is required to make up the missed material through self-study.

Aims

The aim of the course is to introduce students to the fundamentals of low-temperature physics and technology, and to their applications in the design of cryogenic equipment for physical experiments, scientific research, medicine, energy, and industry.
Students will gain knowledge of physical phenomena and material properties at low temperatures (phase transitions, changes in thermal, electrical, and mechanical properties, superconductivity, superfluidity, etc.). They will also acquire basic skills for laboratory work at low temperatures in the range of 1.5 K to 300 K and an understanding of the principles of cryogenic system design.
