A POSTDOCTORAL POSITION is available immediately within the Laboratory
Astrochemistry team of the Institute of Physics of Rennes at the University
of Rennes 1, in Brittany, France.
http://www.ipr.univ-rennes1.fr/wiki/index.php/EN/astro/accueil
The successful applicant will participate in the CRESUSOL project, funded by
the French ANR (National Research Agency). The main aim is to measure rate
constants and in particular product branching ratios at substantially lower
temperatures than has been attempted before (down to 20 K), for a selection
of reactions of importance for interstellar environments and planetary
atmospheres.
For this purpose, a new, pulsed version of the CRESU technique will be
coupled with synchrotron VUV photoionisation mass spectrometry. The CRESU is
the only technique capable of measuring the rate coefficients for reactions
at temperatures as low as 6 K^1-2 , and the cw DESIRS VUV undulator-based
beamline of the synchrotron SOLEIL, which is a state-of-the-art beamline
providing high flux, spectral purity and high spectral resolution over the
whole VUV range (5-40 eV), will be used in this study.
The candidate will first participate in kinetics measurements based on VUV
laser-induced fluorescence experiments using the current CRESU apparatus
available at Rennes. He/she will also participate in the development and
implementation of a mass spectrometer in a chamber equipped with a new,
pulsed, version of the CRESU in which preliminary experiments will be
undertaken at Rennes. The candidate will benefit from the experience of the
members of the Rennes and SOLEIL (Laurent Nahon and co-workers) groups in
the different fields involved. During the project, strong interaction will
also be maintained with the theoretical group of Stephen Klippenstein and
Lawrence Harding at Argonne National Laboratory (USA), third partner of the
CRESUSOL project.
We are looking for someone with a solid background in experimental
physics/chemical physics/physical chemistry. Candidates with experience in
lasers, mass spectrometry and photoionisation techniques are encouraged to
apply. Experience in rarefied flows and/or data acquisition would be
advantageous.
The initial appointment will be for one year, with the possibility of
renewal. The salary is competitive and commensurate with experience (gross
salary > 27 550 EUR).
Applicants should send (preferably by email) a letter of introduction, a
full CV and the names and contact details (emails) of three referees to
