  text: In this work, we discuss the possibility of improving charge neutralization
    in near ambient pressure X-ray photoelectron spectroscopy by co-irradiating the
    sample with He I photons of 21.2 eV. This UV-enhanced neutralization of charges
    is a variation of the so-called environmental charge compensation, which uses
    the electrons produced by the photoionization of the ambient gas to neutralize
    the positive charges built at the sample surface. Adding an additional ionization
    source generates more charges at the sample but also larger amounts of electrons
    available for neutralization. The final surface charge equilibrium depends on
    different aspects of the experiment, such as the sample composition and geometry,
    the total ionization cross sections of the gas compared to the surface materials,
    the gas used, the luminosity and spot size of the sources used for photoionization,
    and the energy of the electrons present in the gas phase. Here we illustrate the
    efficiency of the UV-enhanced neutralization using three different dielectric
    samples with different geometries (a porous SiO2 monolith with an irregular surface,
    a flat mica sample, and a thin SiO2 film deposited onto a Si substrate), different
    X-ray spot sizes, and two different gases (N2 and Ar). The effect of biasing on
    the efficiency of the sample surface to attract electrons produced in the gas
    phase is also discussed.
