Cryogenics (FSI-TK0)

Academic year 2020/2021
Supervisor: Ing. Pavel Urban, Ph.D.  
Supervising institute: ÚFI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
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.
Learning outcomes and competences:
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.
Course contents:
Basics of low temperature physics and cryogenics.
Teaching methods and criteria:
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
Controlled participation in lessons:
Absence has to be compensated by self-study or assigned homework. Presence in laboratory exercises is obligatory.
Type of course unit:
    Lecture  8 × 2 hrs. optionally                  
    Laboratory exercise  5 × 2 hrs. compulsory
