The Electronics, Detectors and Computing Division
Sédi

COMPASS Micromegas detector The active areas of the detector is 40x40cm2. They allow a spatial resolution of 65µm and a time resolution of 10ns. The 12 detectors have been installed since summer 2002.

Sédi numbers 77 engineers and researchers, 68 technicians, two post-doctoral students and two apprentices working on the development of detection and data processing systems for the department’s physics experiments.

The technical performance of instruments and computer systems has for a long time played a key role in the quality of physics experiments, which are becoming increasingly demanding in terms of performance (speed, precision), reliability and data flow. Sédi has state-of-the-art expertise in several scientific and technical fields such as detector physics, analog front-end electronics, filtering and trigger electronics, real time computing and software engineering. These specialties are deployed not only as part of physics programs but also within a number of specific R&D programs. The applied use made of them by other units of the CEA and by industry demonstrates the service’s ability to provide innovative solutions in these fields.

 

Sédi’s laboratories
Sédi was set up in January 2002 in response to a need to bring complementary specialties such as the physics of detection and front-end electronics, or real-time computing and digital electronics, together in a single unit. This need has arisen as a result of the long-term evolution of scientific instrumentation, the complexity and performance requirements of which demand the creation of multidisciplinary teams cemented by a strong «system vision», whose activities range from architecture to integration and testing.
Sédi’s laboratories are set up along this page, aiming to foster exchanges between technical specialties while maintaining the necessary links between «upstream» and «downstream» activities.
