01
Cutting-Edge Capabilities
Advanced testing methods including laser doppler vibrometry systems from small to large scale structure, excitation capabilities from impact hammer to large vibrator trucks and state of the art spectrum analyzers.
02
Support the LHC Operation
Colliding particle beams with diameters of a few tenths of a micron at nearly the speed of light requires precise vibration control for all supporting systems, including cryogenics, cooling, and ventilation. Civil engineering activities related to human activities play a crucial role.
03
The CERN Seismic Network
System developed to monitor seismic activity in and around the LHC and its associated facilities. Our network is connected to the international monitoring organizations and allows geophysicists to study the local seismic activity.
04
Future Circular Collider (FCC)
Experienced engineers and technicians specializing in vibration and ground motion assessment play a key role in supporting the design of future high-energy physics accelerators, such as the FCC, which demands stringent stability requirements.
05
Active Stabilization System
The Compact Linear Collider (CLIC) project at CERN aims to achieve unprecedented precision in particle acceleration and collision. The main beam quadrupole magnets must be controlled to the nanometer level to maintain beam quality and luminosity thanks to an active stabilization system.
06
Material Testing
Mechanical properties can be extracted using impact testing methods. Standardized techniques are fast, non-destructive to materials, and well-suited for expensive or activated materials.
