Mer information

In preparation for the High-Luminosity LHC phase, the CMS collaboration is working on an ambitious upgrade of the first stage of its online selection system, the Level-1 (L1) trigger. The upgraded system will use powerful FPGA processors connected through a high-bandwidth network, paving the way for more sophisticated online algorithms such as Particle Flow reconstruction.

By joining the team, you will contribute to the development of these algorithms, their implementation in firmware, and the evaluation of their physics performance.

Your responsibilities

  • Contribute to the development of algorithms for the CMS Level-1 (L1) trigger.
  • Integrate and maintain contributions from other developers to support collaborative project development.
  • Evaluate the physics performance of the algorithms and contribute to the development of monitoring systems.
  • Participate in the hardware testing and installation of the upgraded trigger system.
  • Collaborate closely with members of the CMS L1 trigger groups at CERN.
  • Present project progress and results at collaboration meetings, workshops, and international conferences.
  • This role includes team supervision responsibilities.
