Equipment responsibility

The TCD section is responsible for all beam-intercepting devices in the CERN accelerator complex, including beam collimators, particle producing targets, beam dumps and absorbers, beam stoppers, passive masks, slits as well as scrapers. Get to know more about these in the Projects and Equipment‘s page.

BID Project development

The section carries out conceptual studies, manufacturing, installation and maintenance of the mechanical systems and associated equipment, and collaborates in the integration of mechatronics systems needed for operation. The section teams organize and undertakes expert interventions in the beam facilities to carry out mechanical repairs or upgrades of its devices.

The section is responsible for thermo-mechanical studies of all beam-intercepting devices (BID) in the accelerator sector, including fixed targets, collimators and dumps/absorbers. It is also in charge of the conceptual design, R&D activities and operation of fixed target stations as well as of dump/shielding assemblies for the whole CERN accelerator complex.

Material R&D

As an integral part of these activities, the section is constantly developing its expertise in the behaviour of materials under extreme working conditions as well as their behaviour after irradiation (long-term damage and single shot dynamical effects) to predict the evolution of the material response during operation. Research and development activities aiming at the improvement of design of cooling assemblies for beam intercepting devices is also executed in the TCD section.

Facilities Coordination

The section is in charge of the technical coordination and supervision of the n_TOF Facility as well as of the AD antiproton target area.

Other Tasks

The section is also in charge for the design, tests and operation of focusing magnetic horns for the CERN accelerator complex. Studies on the use of remote handling and manipulation and improving the design of beam intercepting devices including remote handling techniques are also carried out within the section.

Activities as part of a project

Many of the activities performed in the section are strongly linked between each other throughout the course of a project. People, software tools along with the mechanical workshops are essential during its development up until the project conclusion with success. It is therefore essential to have all of them excelling at their best.

Typical BID project workflow, highlighting tools and means to perform the tasks and how it is inserted in the global activity type performed in the TCD section.

The above scheme could even be related with a BID for a Facility coordinated by the section. This would therefore involve all the core activities in a single project!
