Vacuum and Cryogenics Physics and Technology

Recommended Prerequisites

  General Physics, General Chemistry, Physics Mechanics, Atomic and Molecular Physics  

Teaching Methods

In lectures the teacher will write the diagrams/drawings and sequences of mathematical formalism in question. Whenever possible we resort to the presentation of practical examples for greater objectivity and better learning by students. The practical classes are for demonstration so that students make contact with the operation of various vacuum systems. At the start of practical work where students will operate autonomously vacuum systems, there will be a brief discussion about the objectives of the work, the procedure to follow to achieve those objectives and expected results.

Learning Outcomes

 This course aims to provide knowledge of general physics and technology of the vacuum and cryogenics and allows contacts and experiences with distincts vacuum systems, so that students may in future use, develop or maintain those systems. Rather than providing a detailed training on fundamental physical processes involved, it is essentially intended to contribute to a practical and technical training in the operation and selection of different vacuum equipment and the identification of limitations that may be in a given system. The student will have to develop skills for consulting manuals of different manufacturers of vacuum equipment in order to extract the information most relevant to their needs.
Skills to develop:
Competence in analysis and synthesis, competence in information management, decision-making capacity; Competence in independent learning.
