Course detail

Cryogenics

FSI-TK0 Acad. year: 2020/2021 Summer semester

Basics of low temperature physics and cryogenics.

Language of instruction

Czech

Number of ECTS credits

3

Learning outcomes of the course unit

Knowledge about physical phenomena and matter properties at low temperatures, basics for work in low temperature laboratory (1,5 K – 300 K).

Prerequisites

Basic course of physics.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

The condition for award of the course-unit credit is a student’s work: design of a simple cryogenic equipment or experiment

Aims

The aim of the course is to present basics of low temperature physics, technology and design of low temperature equipment for physical experiments and other applications.

Specification of controlled education, way of implementation and compensation for absences

Absence has to be compensated by self-study or assigned homework. Presence in laboratory exercises is obligatory.
