Description of the thesis topic

As part of an R&D for particle physics, we are looking for a doctoral student who will work on the design and characterization of a mixed integrated circuit. This ASIC will read a detector from the EIC electron-ion collider planned at Brookhaven in the next decade. A new type of detector silicon with amplification (AC-LGAD) which appeared just a few years ago should make it possible to combine the excellent temporal resolution (20 ps) of these detectors with a spatial resolution (10 um), allowing a new generation of pixel detectors with precise time measurement. Of course, to achieve this performance a very compact, fast and low power reading integrated circuit must be developed. Relying on its former expertise on the classical LGADs of the ATLAS experiment, OMEGA proposes the study of new architectures of ASICs for these new generation detectors.

Work Context

Omega is a CNRS-IN2P3-Ecole Polytechnique microelectronics design center located in Ecole Polytechnique Campus in Palaiseau, in the southwest suburb of Paris. It is composed of a team of a dozen of microelectronics engineers designing sophisticated ASICs for nuclear physics, particle physics and astrophysics detectors.

Constraints and risks

Occasional international missions possible (CERN Suisse, Brookhaven USA, other countries)
Possible tests and measurements (Testbeam, irradiation tests)
