Introduction


The laboratory hosts three platforms and has specific rooms for various projects and activities. In order to meet its commitments on the various projects in which it participates, CPPM has acquired equipment in the various technical fields of electronics, mechanics and computer science.

Platforms


The laboratory hosts three platforms:

  • the underwater infrastructure and the ANTARES detector,
  • infrastructure (MEUST), the KM3NeT/ORCA detector and a new instrumentation for the study of the marine environment (NUMerEnv),
  • intensive computing infrastructure.

ANTARES platform

The ANTARES platform covers both the underwater infrastructure and the ANTARES detector. In addition to the neutrino aspects, this infrastructure has made it possible to develop collaborations with scientists from the Marine, Earth and Environmental Sciences, in particular with the DT-INSU of the CNRS (Technical Division of the National Institute of Sciences of the Universe), the MIO (Mediterranean Institute of Oceanology) for oceanology and the marine environment, the LSIS (Laboratory of Information and Systems Sciences) for the bioacoustics of cetaceans and the Géoazur laboratory for seismology.

MEUST - KM3NeT/ORCA platform - NUMerEnv

The underwater infrastructure (MEUST), the KM3NeT/ORCA detector and a new instrumentation for the study of the marine environment (NUMerEnv) constitute a platform on the French site (KM3NeT-Fr) of the European KM3NeT project. It also represents the West-Ligure node of EMSO which will be used on environmental aspects by our colleagues from the DT-INSU of the CNRS (Technical Division of the Institut National des Sciences de l'Univers), the MIO for oceanology and the marine environment, LSIS (Laboratory of Information and Systems Sciences) for cetacean bioacoustics and Géoazur for seismology, aspects on which our collaborations are being strengthened.

This project is financed with the support of the European Union with the European Regional Development Fund.

HTC/HPC platform

The EGI-INSPIRE project, financed by the European Commission, is the follow-up of the original EGEE projects which were completed in May 2010. The feasibility of a production level computing grid infrastructure was successfully demonstrated. The EGI infrastructure, based on national initiatives NGI France-Grille, provides European industry and research, access with this grid infrastructure, which is already extending over 260 sites in over 50 countries.

The project will focus on several primary goals:

  • To combine national, regional and dedicated grids in a single unique infrastructure to serve scientific research and to construct a solid computing grid for commercial research and industry;
  • To continually improve the software quality so as to provide a reliable service to users;
  • To attract new scientific and industrial users by allowing them to discover the great potential offered by the computing grid and to ensure that they receive a high quality of training and support.

The grid makes use of the European Union’s high bandwidth network, GEANT, and exploits the vast expertise accumulated in the many national and international grid projects, past and present.

The CPPM computing departement is running a LCG Tier-2 grid node. The node aims to serve the analysis requirements or the laboratory’s physicists as well as those of other scientific researchers in Marseilles, as well as contributing computing and storage elements to the grid. A new project is under study. It should offer a large computing infrastructure (about 2000 cores) and subsequent storage (about 1 PB) to different laboratories located on the Luminy Campus.

The High-Performance Computing infrastructure (mainly Grid computing until now - France-Grille and Tier 2 of LCG France), is developing a Cloud modality for the entire AMU scientific community. This will be possible thanks to an AMU project carried out in collaboration with the AMU HPC mesocentre through CPER and FEDER fundings. The project will set up a shared but distributed platform (Grid and Cloud in Luminy) and HPC (in Saint-Jérôme) accessed in a unified way for AMU users through the DIRAC software.

Specific rooms


For the projects KM3NeT/ORCA, imXgam, Euclid and for the activities in calculation, the MPCC has specific rooms:

  • darkroom for KM3NeT,
  • imaging" rooms for imXgam,
  • clean rooms dedicated to the characterization of infrared detectors for Euclid, to microelectronics as well as to assembly and measurement,
  • computing room.

Darkroom

For the KM3NeT/ORCA project, the CPPM manufactured a 50 m² darkroom to test a complete detection line and thus produce the number of lines needed for the experiment.

Imaging rooms

For all aspects of biomedical imaging requiring the use of sealed or unsealed sources, CPPM has two rooms of approximately 25 m² each. The first room houses a testing device for an X-ray device and the second room receives dedicated equipment for the use of unsealed sources for TEP/CT images: glove box, shielded workbench, shielded sink with decantation tank.

Clean rooms

The characterization of infrared detectors for the Euclid experiment required the installation of a dedicated clean room (ISO7 - ISO5) capable of receiving the two cryostats built specifically for the characterization of flight detectors. Two others are also required for microelectronics and for mounting and measuring.

Computing room

The computing room, which in addition to hosting the current grid node, will host the cloud modality and additional resources planned in the M3AMU project. CPPM computer room is a network/telecom mixing part of about 20 m² and an application and file servers, networks and computing grid part of about 60 m². In addition to its own computer resources, the CPPM hosts computer equipment (calculations and storage) for another laboratory of the Luminy campus (INSERM).

Specific equipment


In order to be able to meet the commitments on the various projects, CPPM has equipped itself with equipment in the various technical fields of electronics, mechanics and information technology.

To develop both electronic boards and integrated circuits, CADENCE tools ( computer-aided design, market negotiated by IN2P3) are heavily used by the entire electronic service in all phases of development: design, simulation, realization. In addition to standard measuring devices (power supplies, generators, oscilloscopes), CPPM has acquired very high bandwidth tools (25 GHz) in order to be able to test ultra-fast links on optical fibres. More targeted towards microelectronics, CPPM can test 8-inch wafers and micro-wiring 25 μm in aluminium wire. These materials are placed in a clean room.

As in electronics, the mechanical department has the entire CAO/FAO (computer aided design & manufacturing) chain (software: CATIA) to go from design to mechanical manufacturing via finite element calculation (ANSYS). For manufacturing, the mechanical workshop includes conventional and CNC machining machines as well as rapid prototyping machines (3D printer - plastic). Two large metrology systems (contact and vision) allow inspection and assembly to be carried out with better than micron accuracy, as well as a movable arm, in order to verify and accurately mount sub-assemblies. These systems are arranged in a clean room.
