The physics programme at CERN presents a multitude of technical challenges that
can involve working on a microscopic scale or on enormous machines. To
successfully conduct their experiments at the forefront of knowledge, physicists
rely on groundbreaking, often huge machines built using millions of components
and offering an unprecedented level of precision. This is the reason why CERN
employs several hundred engineers and technicians, who develop, build and test
these machines and keep them in good working order.

The construction of particle accelerators and detectors requires cutting-edge
technologies such as radiofrequency cavities to accelerate particles,
superconducting magnets to alter their trajectory, cryogenics to cool the
magnets down and make them work, and vacuum to allow the beams to circulate.

Detectors present other technological challenges. Their components and
subsystems are designed, built and tested individually before they are assembled
together to work in harmony. Kilometres of wiring and thousands of electrical
components make particle detectors a considerable feat of engineering.

Engineers push back the limits of technology so that physicists can carry out
their research. Their innovations are then used in other fields thanks to
knowledge transfer activities.
