CERN Accelerating science

Department Structure

Group Group Leader Mandate
Katy Karine Foraz

The EN-ACE Group is responsible for:

  • Providing overarching project coordination for the accelerator complex, including layout management, integration,scheduling, work and safety coordination, as well as for different projects;
  • Providing support and expertise in matter of project, risks and quality management as well as organizational process;
  • Developing and supporting the Organization's engineering, equipment data, maintenance management tools and mechanicals CAD systems.

Luigi Serio

General administration, mamangement and planning of the department resources.
Coordination and assessment of performances of the Organisation technical infrastructure.


Mauro Nonis

The mandate of the CV group concerns the operation and maintenance of the cooling systems, pumping stations, air conditioning installations and fluid distribution systems for the PS, SPS and LHC including their experimental areas and special cooling systems of LHC sub-detectors. It also provides service to the Computer Centre and some miscellaneous installations.

Markus Brugger

The group is responsible for all beamlines, the infrastructure and the management of CERN’s fixed target experimental areas, as well as for irradiation and beam test facilities (East Hall, North Area, the Antiproton Decelerator experimental area, AWAKE and HiRadMat). It furthermore supports the LHC experiments and facilitates the interface with the Accelerator and Technology Sector. It participates in and partly hosts the management of a number of CERN-wide projects (East Area Renovation, CERN LHC Hostlab Project, AWAKE, HL-LHC WP8, etc.).

Nicolas Bellegarde

The EL group is responsible for the CERN electrical distribution network from 400kV to 400/230V. Its main missions are to operate, maintain, extend and renovate the network, analyse and make projections for CERN electrical energy consumption and manage relations with the energy suppliers.

Ingo Ruehl

The mandate of the Handling Engineering (HE) Group is to provide transport and handling services for the technical infrastructure of CERN, accelerators and experiments. This includes the design, the tendering/procurement, the installation, the commissioning, the operation, the maintenance and decommissioning of standard industrial and custom built transport and handling equipment.

Francesco Bertinelli

The mandate of the MME group is to provide to the CERN community specific engineering solutions combining mechanical design, production facilities and material sciences. This group owns, maintains and develops the 30 years old know-how on the mechanical construction of beam accelerators and physics detectors.

Alessandro Masi

The SMM Group develops and maintains a centralized competence in Survey, Mechatronic systems, tests and Measurement. The group is in charge of maintaining a competence in the development of radiation tolerant electronics, and provides support CERN wide for radiation tests and radiation monitoring for evaluating the dose to electronics installed in radiation areas. The group develops robotic platforms adapted to interventions in the accelerator environment, and deploys those solutions in collaboration with all groups in the Accelerator and Technology sector. SMM is able to provide computing support for data acquisition, data processing and data analysis, as well as for data storage related to all these activities.

Simone Silvano Gilardoni

The Sources, Targets and Interactions Group will have as common ground the study of beam interactions with matter, aiming to apply its know-how to particle generation (ISOLDE Radioactive beam sources, CLIC photoinjectors and polarized e+ e- sources), and to particle interception (collimators, absorbers and dumps). The Group is in charge of the conceptual design, production, operation and maintenance of devices in the LHC injectors and the LHC machine (sources, targets, collimators, dumps etc…) as well as in the secondary beams. The group is responsible for developing and maintaining the FLUKA Monte Carlo code and for providing formal training and support to its users in the accelerator community and to the experiments worldwide.
