    • Making the height of the mica sheet greater than the distance separating the nozzle blocks ensures that the inner surface of the nozzle is smooth in the supersonic region and, thus, avoids introducing weak shocks into the flow. The strength of the thin mica sheets limits the height of the side wall slit to 1 mm

    • Aerosol polydispersity may also be affected by the presence of boundary layers next to the nozzle walls. Model calculations by Schnerr et al. 18 found that within the boundary layer nucleation occurred further downstream as the wall was approached. The average particle size, however, rapidly approached that of the aerosol in the main stream. Based on the measurements of Tanimura et al., 9 we estimate that at most 5% of the aerosol is formed more than 1 cm downstream of the particle formation event in the main stream. The observed polydispersity, therefore, is a result of the inherent polydispersity of the aerosol, modified slightly by particle formation in the boundary layer, and of the resolution functions of the instruments including the aperture size, the wavelength distribution, and the finite pixel size. The instrument factors associated with X-ray scattering are all much smaller than those of our earlier neutron scattering studies
