The scope of the course can mainly be divided into three big fields that are carried out on ESS which is accelerator-, instrument- and target department. Key topics and different components will be highlighted in each department such as: particle acceleration techniques used in ESS, spallation targets, different neutron instruments which are used for the experiments. Different fields within cryogenic engineering (fluid & material properties, cryostat design, refrigeration techniques, thermal insulation systems). Superconducting radiofrequency systems for example: niobium cavities, power couplers, tuning systems and cryomodules. Radiofrequency engineering (RF system basics, klystrons, IOTs, high voltage power supplies). Vacuum systems and different components for example: pumps, gauges, vacuum system design. Beam instrumentation design. Different accelerator magnet design for the ESS, Control systems (ESS architecture, PLCs, EPICS software). Topics outside the three major topics will also be included for example project management basics (scope, cost & schedule, WPS development, risk and contingency), applications and analysis, different research fields and also environmental aspects.
