SOLEIL is the French national synchrotron facility, located on the Saclay Plateau near Paris. It is a multi-disciplinary instrument and research laboratory whose mission is to conduct research using synchrotron radiation, to develop cutting edge instrumentation on the beamlines, and to make these developments available to the scientific community. SOLEIL synchrotron, a unique tool for both academic research and industrial applications across a wide range of disciplines including physics, biology, chemistry etc., opened in 2008. It is used annually by thousands researchers from France and abroad. SOLEIL is based on a synchrotron source that is state-of-the-art both in terms of brilliance and stability. This large scale facility, a partner of the Université Paris Saclay, is a “publically owned” private company, founded by the CNRS and the CEA.

This position is in the Detectors group of the Experience division. The Detectors group mission consists to develop, realize and operate performant experimental devices, necessary to the well-functioning and to maintain the best level of competitiveness of the beam lines. In this context, the Detectors group is developing, with several European partners, a fast photon counting detector, based on hybrid pixel technology, in order to improve the detection performance of beamlines for different types of experiments: time resolved diffraction experiments, kinetic studies, and other experiments requiring a fast readout and granular detector.

I. Missions

The postdoctoral fellow will carry out two main tasks: first, take in charge the all the tests (in the laboratory of the Detectors group) from debugging up to final performance tests of several detector prototypes (with different geometries), according to acquisition modes specific to the type of experiment, including the development/adaptation of data analysis software tools and writing of test reports. This phase of laboratory tests is an essential step in the preparation of the detector for a given type of experiment. Second, he (she) will also be responsible for the preparation and installation of detector prototypes on beamlines, and will participate in commissioning tests and first experiments, with, depending on the case, participation in data analysis. Some trips may be necessary. He (she) will present the results in synthesis meeting of the experiments carried out and in conference at the international level.

II. Training and experience

The candidate must have a PhD in Physics and Instrumentation or associated subject. He (She) must have a solid knowledge in detection techniques in semiconductors, essential knowledge in radiation-material interactions and an ability to develop software programs in C/C ++ and/or Python. Knowledge in electronics would be greatly appreciated. A strong interest for laboratory experiments is also required. Candidates must be fluent in English and a good level in French is also an advantage.

III. General conditions

This job opportunity concerns a postdoctoral fixed-term contract of one year (renewable one year).
