An opportunity has arisen within the Particle Physics Department (PPD) of the STFC Rutherford Appleton Laboratory (RAL) to work on the new Level-1 Calorimeter Trigger (L1Calo) as part of the upgrade of the ATLAS experiment at CERN. The Trigger is essential for ATLAS to ensure that the experiment collects the correct and best physics data. The trigger is being upgraded in preparation for increased collision rates following improvements to the LHC luminosity. The RAL PPD group is responsible for design and manufacture of components of the Level-1 electron and tau triggers, and together with colleagues from UK universities will install, commission and operate the system within ATLAS at CERN. This post is a consequence of the imminent retirement of a senior member of the group working towards commissioning of the new systems.

Duties/Work Programme/Responsibilities

You will be involved in the ATLAS experimental programme, understanding the Standard Model of Particle Physics and searching for new physics. To contribute to the collaborative work, you will work on the design of the L1Calo, ensuring that the physics needs are captured.

You will:

  • Become a member of the RAL PPD ATLAS L1Calo Group, working closely with other group members and with engineers in RAL Technology Department
  • Take responsibility for L1Calo online software development at RAL
  • Test the Trigger by examining its performance on real and simulated data
  • Oversee integration and debugging of the Trigger system in preparation for the installation, commissioning and operation at CERN
  • Work closely with members of related detector teams within ATLAS and with the ATLAS Trigger and Data Acquisition community
  • Contribute to future development of the Level-1 Trigger system
  • Spend a fraction of your time contributing to ATLAS physics analysis.

Contacts and Communication

The post is within the ATLAS L1Calo Group at RAL. Close working is essential with collaborators in UK universities and in an international environment at CERN and elsewhere. You will become a member of the international ATLAS experiment.

Further Information

The post will be based at RAL and further information is available from Dr R. Middleton, Information on ATLAS and RAL Particle Physics department is available on the World Wide Web at

Please also supply 2 or 3 letters of recommendation, which should be sent separately to
