Light Source Effects on Aerosol Photoacoustic Spectroscopy Measurements.

Photoacoustic spectroscopy measurements of flame-generated soot aerosol coated with small amounts of water yielded absorption enhancements that were dependent on the laser used: quasi-continuous wave (Q-CW, ≈ 650 ps pulse duration and 78 MHz repetition rate) versus continuous wave (CW). Water coating thickness was controlled by exposing the aerosol to a set relative humidity (RH). At ≈ 85 % RH,...

Swiss Light Source VUV beamline, Imaging photoelectron photoion coincidence spectroscopy

An imaging photoelectron photoion coincidence spectrometer at the vacuum ultraviolet (VUV) beamline of the Swiss Light Source is presented and a few initial measurements are reported. Monochromatic synchrotron VUV radiation ionizes the cooled or ambient temperature gas-phase sample. Photoelectrons are velocity focused, with a resolution better than 1 meV in order to detect threshold electrons. ...
