Mechatronics systems integrate mechanical, electrical, electronic and control systems in order to perform robust and repeatable tasks. At CERN mechatronic systems are used throughout the accelerator complex and experimental halls largely for the control of Beam Intercepting Devices (BIDs). Please click on the different

Beam-intercepting systems are essential devices designed to absorb the energy and power of a particle beam. Generally, they are classified in three categories depending on their use: particle-producing devices, such as targets; systems for beam cleaning and control, such as collimators or scrapers; and those with safety functions, such as beam dumps or beam stoppers. The function of the CEM group is to provide the actuators, sensors and controls for the mechanical systems in order to ensure their correct operation, provide information for monitoring that can be used for performance optimisation, post-mortem analysis and preventative maintenance.

Mechatronic systems are also being developed to expand the electronic infrastructure of CERN. The knowhow developed at CERN over the last 50 years with these systems allows us to advise on actuator, sensor and control choices in harsh environments and to ensure new projects that we develop are safe and reliable for operations.

The main challenges at CERN in terms of mechatronics are:

  • Robust operation with radiation and electromagnetic interference
  • Sensor design
  • Control of actuators over long cables
  • (Usually) Inaccessible environment
