Objectives To introduce the physical processes and laws that control characteristics of a gas, its behaviour under various conditions and its interaction with solid surfaces: their primary physical meaning, consequences, and actual implementation through mathematical relationships. To give students knowledge of vacuum technology including various types of vacuum pumps, pressure gauges and other basic components constituting a typical vacuum system (in combination with laboratory visits).

At the end of the course the student should: (i) understand in detail the laws that control processes relevant for vacuum technology, including gas flow, adsorption and desorption, be able to apply these laws to describe processes in vacuum systems and on solid surfaces and estimate their practical consequences. (ii) be familiar with different types of vacuum pumps and pressure gauges and (iii) understand how to apply the concepts they have learned to planning and performing laboratory experiments that require vacuum.
