Offer Description

The Grenoble Laboratory of Subatomic Physics and Cosmology (LPSC) (http://lpsc.in2p3.fr ) is a joint research unit associating CNRS-IN2P3, Université Grenoble Alpes (UGA) and Grenoble INP school, for an average staff of around 230.
The PhD student will be assigned́(e) to the “Observational Cosmology” group made up of 11 LPSC staff.

The main goal is to mitigate the limiting systematic effects for the next generation of cosmic microwave background experiments. This will require the identification and modeling of instrumental systematics effect, detailed high-precision measurements in the laboratory and the development of calibration procedures during operations.
The student will be in charge of specific tasks such as:
1) She/He will actively participate in the group's experimental activities mentioned above through daily work in the millimeter laboratory at the LPSC and at the Néel Institute.
2) Based on previous work, she/he will define the main scientific requirements of the new instrument in close collaboration with the instrumental and analytical teams. She/He will also optimize the main instrumental and topographical parameters such as overall sensitivity and observation time, frequency sampling, polarization capabilities and sky coverage.
3) She/He will also join the LiteBIRD and COSMOCal collaborations. In addition to promoting our instrumental and scientific solutions, she/he will gain expertise in precise systematic characterization and modeling. He/she will be able to apply the experience acquired on the development of the test bench for spectral and polarization characterization.
