Laboratory of Mechanical Studies and Detectors Integration (LEMID)

The laboratory

The LEMID is a group of about fifteen permanent employees, composed of engineers and technicians, whose main activities cover the development process of mechanical components for detection systems, the assembly of the detectors themselves, and the integration of detection systems on-site. Besides, the LEMID welcomes and trains students, interns, apprentices, in the frame of their education.

The laboratory’s skills in design combine the fields of mechanics and electronics in order to create detectors matching physics’ needs.

Integration of a detector in a cleanroom

LEMID's productions

Mechanics of detection systems : Definition, design, manufacturing in our facilities (or management of production subcontracting when needed), and assembly of mechanical components constituting the mechanical structure of the detector and/or allowing to integrate the detector within the research facility.
Detectors assembly : Definition and development of assembly techniques including the design of needful toolings for the construction of detectors, considering all their constraints. These operations are likely to be realised in our cleanrooms.
Integration of detection systems on-site : Participation in the operations of installation and commissioning of the detection systems within experimental facilities, when the Irfu has the responsibility of those operations.
Production of MicroMegas detectors :
- Participation in the definition of Printed Circuit Boards (PCB) with specific patterns
- Supplying through industry
- PCB transformation by implementation of structures created by lithography and silk-screen printing
Development and production of tests benches : Development, supply, and assembly
