The Paul Scherrer Institute concentrates its activities on
solid-state research and materials sciences, elementary particle
physics, energy and environmental research as well as biology and
medicine. One of the challenges for the Combustion Research Laboratory
is the development of non-intrusive optical measurement techniques
(laser spectroscopy) suitable for flame diagnostics.
The aim of this PhD project is to study collisional processes
that affect the detection of nitric oxide by laser-induced fluorescence
(LIF) in high pressure combustion (up to 40 bar). This also includes LIF
of oxygen which is the main interfering species at fuel-lean conditions.
The impact of pressure, temperature and flame composition on signal
intensity and detection sensitivity will be assessed, as a function of
excitation and detection wavelengths. This study will aid the
development of a technique to measure and analyze NO LIF signals at high
pressure and temperature, at conditions similar to those encountered in
gas turbines and Diesel engines. This characterization of flames at
realistic conditions can serve as a powerful tool towards the
development of emission reduction techniques.
We are looking for candidates who have a university degree in
physics or chemistry with strong background in physical chemistry.
Talent for experimental work and experience in optical measurement
techniques are essential, good communication skills in English are a
plus. As a member of a small motivated team, you will need to make an
important contribution in order to successfully meet the research goals.
