Performance Evaluation

PE Slideshow

The Performance Evaluation section (PE) is responsible for a wide range of R&D, studies, simulations, experiments and data analysis aiming to further enhance the operational performance of the LHC and to optimize performance of future accelerators. The current responsibilities of the section include amongst others:

  • Studies of protection issues for superconducting magnet circuits to assure reliable operation at nominal energies.
  • Monitoring of the evolution of the magnet circuit performance throughout the various operational conditions.
  • Development of tools to simulate and understand the electrical behaviour of magnet circuits, focusing on transients, shorts-to-ground and other nonconformities that could hamper the protection of the circuits.
  • Machine protection studies to analyse and assure the coherency of machine protection across the equipment and protection systems. This includes establishing quench and damage levels as a result of accidental beam impact on accelerator components as well as studying the reliability of the present and future machine protection systems.
  • Assisting to the commissioning of the superconducting magnet circuits and machine protection systems, and supporting LHC operation in periods with and without beam.
  • Coordination of the studies for CERNs LInear Collider (CLIC) machine protection systems and other future accelerators such as the High Luminosity LHC upgrade (HL-LHC) and the Future Circular Collider (FCC).

The PE section is a dynamic team of accelerator/experimental physicists and electrical engineers with a very good knowledge of superconductors, magnets, accelerators and various protection systems. We also have a broad skillset in simulation, modelling and data analysis (using tools such as Matlab/Simulink, PSpice, COMSOL, LabView, MAD(X), FLUKA, Isograph, Finite element modelling …). We work closely with equipment and protection experts as well as the operation crews and CERNs controls, and follow the daily operation and optimization of CERNs accelerator complex.
