ATLAS Organisation - Description of appointments


You will find here a brief overview of the ATLAS organisation. More details are provided on the role of the Spokesperson and members of the executive board and the electoral process. Details are also provided in the original MoU.

ATLAS Management


  • The Spokesperson is the highest level executive of ATLAS, and as such has the overall responsibility of the ATLAS execution and organises the day-to-day execution of the project. The Spokesperson represents the ATLAS executive branch at the Collaboration Board and the Collaboration to the LHC Committee, to the CERN Management, and to the outside world.
  • The Spokesperson is elected on an individual basis by the Collaboration Board, after nomination of candidates by, and in due consultation with, the Collaboration. ATLAS will normally have one Spokesperson. However, the Collaboration Board can also decide, with a 2/3 majority, to elect two Spokespersons. The term of office is 2 years, renewable once, with a 2/3rd majority. The appointments is made in consultation with the CERN Management.

Deputy Spokesperson

  • The Spokesperson may nominate one or two deputies, who will be elected by the Collaboration Board for the duration of the term of office of the Spokesperson. The responsibilities of the Deputy Spokesperson(s) have to be clearly defined.

Technical Coordinator

  • The Technical Coordinator monitors the technical aspects of the construction of the System, is responsible for the detector integration, for the overall construction of the detector and of the experimental area, and for common project issues and will typically deal with integration issues of the subdetectors, safety, ATLAS infrastructure at CERN, surface and experimental areas, services, installation, machine interface, and test beams.
  • The Technical Coordinator is CERN staff. The appointment proposed by the Spokesperson and is made in in agreement with the CERN Management.
  • Link to appointments database.

Resource Coordinator

  • The Resource Coordinator monitors and manages the financial and human resources of the collaboration and will typically deal with budget planning, human resources planning, Memoranda of Understanding, and the Common Fund.
  • The Resource Coordinator is CERN staff. The appointment is proposed by the Spokesperson and made in in agreement with the CERN Management.
  • Link to appointments database.

Upgrade Coordinator

  • The Upgrade Coordinator ensures that the upgrade programme is well-defined, well-matched to the physics goals, and proceeding well. The Upgrade Coordinator is responsible for reporting on upgrade activities to the Executive Board, and for ensuring that Upgrade Project Leaders are informed of Executive-Board matters that impact on the Upgrade Projects. The Spokesperson and the Upgrade Coordinator work closely together in preparing upgrade-related interactions with the CERN LHCC and Upgrade Cost Group review committees.
  • The Upgrade Coordinator is elected or endorsed by the Collaboration Board from candidate(s) proposed by the Spokesperson. The Spokesperson will be assisted by a search committee, and will call for nominations and feedback from the Collaboration. The term of office is for two years, renewable. The Upgrade Coordinator may be part of the ATLAS Management team, depending on the phase of the upgrade programme (currently is).

ATLAS Project Leaders

  • The Project Leader is responsible to the ATLAS Collaboration for ensuring that the operation of the corresponding System is carried out in a way that guarantees the required performance and long-term reliability. Project Leader manages the operation and maintenance of their system.
  • The Project Leader election starts by first forming a search committee of the Institute Board that calls for nominations from the community. This committee presents a short list of Project Leader candidates to the Institute Board after consulting with the (sub)system community and Management. The appointment is for two years with the possible extension according to the ATLAS organisation rules. If the outgoing System Project leader has served for two terms or longer and seeks reelection, the search committee should actively seek new candidates.

  • LAr Calorimeter
  • Tile Calorimeter
  • Muon Instrumentation
  • Forward Detectors
  • Trigger/DAQ
  • ITk

ATLAS Activities

  • Details of the activity areas.
  • The slate of candidate Coordinators of the Trigger, Computing, Data Preparation and Physics areas is proposed by the Spokesperson. The Spokesperson is assisted by a search committee, and makes a call for nominations and feedback from the Collaboration. The Coordinators are endorsed by the Collaboration Board. The mandate of the Coordinators is for two years, renewable. In the case of the Physics Coordinator, two consecutive mandates is not allowed.
  • The Run Coordinator is proposed by the Spokesperson and the Technical Coordinator. They are assisted by a search committee, and make a call for nominations and feedback from the Collaboration. The Run Coordinator is endorsed by the Collaboration Board.
    • The Publication Committee consists of 10 members, each member serving for two years, and in addition a Chair and a Deputy Chair.The Deputy Chair is elected every two years by the Collaboration Board following a normal ATLAS election procedure. In the second year of the mandate,the Deputy acts as Chair of the Committee.
  • Appointment procedures for Combined Performance group conveners and Physics Analysis group conveners
  • Trigger Coordination
    • This area covers all trigger (LVL1 and HLT) performance issues.
    • Coordinator appointment.
  • Computing Coordination
    • This area covers operation of the offline computing, development and maintenance of the core Software, and overall technical coordination and integration of the core and non-core Software.
    • Coordinator appointment.
  • Data Preparation Coordination
    • This area is responsible for the first three steps of data analysis after the data arrive at the Tier0, and of the corresponding aspects for the simulated events: offline data quality and data treatment; reconstruction, calibration and alignment at the (sub)-detector level; and first combined reconstruction of physics objects by bringing together the information of various sub-detectors, and use of these objects to align and calibrate the various sub-detectors.
    • Coordinator appointment.
  • Physics Coordination
    • This area covers the more refined reconstruction of physics objects, and the development of reconstruction algorithms optimised for different physics channels. It also covers global performance issues, such as the determination of the absolute energy scales of the experiment . Another aspect under the responsibility of Physics Coordination is the extraction of physics results.
    • Coordinator appointment.
  • Run Coordination
    • The Run Coordinator is formally delegated from the Technical Coordinator some of the technical responsibilities related to daily operation during data taking.
    • Coordinator appointment.
  • Publication Committee
    • The Publication Committee Chair is responsible for ensuring that the ATLAS publications are of high scientific and formal standard, overseeing the preparation of ATLAS publications, participating in the release of proceedings, identifying suitable journals for ATLAS publications and ensuring that the ATLAS guidelines and publication policy are followed.
    • Chair appointment.
