Abstract

The micro atmospheric pressure plasma jet is an rf driven (13.56 MHz, similar to 20 W) capacitively coupled discharge producing a homogeneous plasma at ambient pressure when fed with a gas flow of helium (1.4 slm) containing small admixtures of oxygen (similar to 0.5%). The design provides excellent optical access to the plasma core. Ground state atomic oxygen densities up to 3 x 10(16) cm(-3) are measured spatially resolved in the discharge core by absolutely calibrated two-photon absorption laser-induced fluorescence spectroscopy. The atomic oxygen density builds up over the first 8 mm of the discharge channel before saturating at a maximum level. The absolute value increases linearly with applied power.
