Description

The purpose of this module is to introduce the fundamental principals of vacuum science and technology. It will introduce and describe in detail the operating regimes of typically used vacuum pumps and vacuum gauges. Vacuum system design and trouble-shooting will be introduced.

Learning Outcomes

1. Relate basic physical quantities to the description of a vacuum system.
2. Explain the practical significance of vacuum production and state examples of its application.
3. Categorise vacuum pumps and gauges and be able to discuss their applicability.
4. Apply physical principles to written and numerical problems.
5. Communicate their ideas with their colleagues.
