Postdoc in far infrared detection for astrophysics H/F
Sujet de stage
The LSIS "bolometers" group, with over 20 years' international experience, developed the PACS photometer for the Herschel space observatory, based on large detector arrays in the submillimeter range. These bolometers, also used in the PILOT and ArTéMiS projects, have made a major contribution to observations of the cold universe, particularly in star-forming regions. Our current developments concern the next generation of bolometers with very high sensitivity and polarimetric capability, and are part of ESA's Voyage 2050 and NASA's Decadal Survey programs. These developments, carried out in collaboration with CEA-LETI in particular, are currently in a phase of optimizing detector performance and readout modes, with a view to their use in future projects on the ground or in space.
Durée du contrat (en mois)
24
Description de l'offre
You will be part of the LSIS laboratory, which employs around twenty people (researchers, engineers, technicians, students), and will carry out the following tasks:
- In-depth analysis of detector characterization measurements, applying advanced methods and knowledge of low-temperature detection physics (light-matter interaction, superconductivity, cryogenic test methods).
- Active contribution to the physical models developed within the group (from the detector to the complete instrument).
- Broader R&D activities, particularly in the spectro-polarimetric field.
Moyens / Méthodes / Logiciels
Data analysis tools (Python, Matlab) and simulation codes (Comsol).
Profil du candidat
You have a PhD in physics or instrumentation for astrophysics, you must :
have good experience of cryogenic detectors for astrophysics, acquired during a thesis or post-doctorate.
master numerical analysis tools (e.g. Python, Matlab) and simulation tools (knowledge of Comsol would be an advantage).
have excellent written and oral communication skills.
have the ability to work well in a team.
