Missions

Development of kinetic inductance detectors (MKIDS) working in the near infrared and in the visible. This work will include the conception, optimisation, manufacture and characterisation at very low temperatures (around 100 mK) of the detectors, in collaboration with the system enigineer and the instrument scientist to sastisfy the scientific and system goals of the instrument.
It is in particular necessary to conceive new geometries and
implement new manufacture procedures in the clean room before
characterisation of the detectors in the dedicates cryostats.

Activities

Main tasks
- Conception of hyperfrequence circuits based on superconductors, dediccated to the detection of visible and infrared photons, with the help of software for electromagnetic simulations.
- Definition of manufacture procedures to build the detectors
- Validation in the clean room of the procedures and optimisation of the procedures.
- Definition of the tests to validate the operation of the detectors and their performance.
- Execution of the test in a cryogenic environment and analysis of the results.
- Integration of detector arrays in the read-out system of the instrument.
- characterisation of the physical and superconducting properties (resistivity, critical temperature) of the materials used for the manufacture of the detectors.

Skills

-Conception and simulation of hyperfrequency circuits based
on superconductors.
-Manufacture of superconducting circuits.
-Manufacture of kinetic inductance detectors for visible and near-infrared.
-Characterisation of superconducting materials.
-Tests of kinetic inductance detectors for the visible and near-infrared.
-Scientific communication: demonstrated capability of presenting the results in scientific articles on refereed journals.

The researcher candidate will join the GEPI, one of the scientific departments of the Observatoire de Paris, as well as a Mixed Research Unit of CNRS. The unit has an activity that is strongly axed on the study of the formation and evolution of galaxies. The activities are both scientifique and technical. GEPI is structured in two poles; the scientific pole and the instrumental pole. GEPI is deeply involved in the space mission Gaia (responsable for the data reduction for the on-board spectrograph) and on the multi-object spectrographs WEAVE, MOONS and MOSAIC.

The reseracher will be part of the team Research & Technology, within the Instrumental Pole.
This is the team that is occupied with the Gaia and WEAVE activities.

There are 93 members of GEPI of which 17 researchers and research professors.

The researcher will be part of the SPIAKID project, financed by the European Reserach Council (ERC).

Constraints and risks

Part of the activity will take place in the clean room of GEPI,
with use of chemical products. This requires to follow the
regulations and procedures established by the personnel responsible for the clean room.

In the course of the project we may decide to use lasers
for the energy calibration of the detectors.
