The laboratory 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.

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.

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.

Specific Equipments

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.
