Abstract The present work is part of a wider project aimed at improving the description plasma dynamics during production phase Helicon Plasma Thruster. In particular, was focused on development chemical model for Argon- and Xenon-based plasma. developed consists collisional radiative suitable to describe 1 s 2 p excited levels. meant be complementary 3D-VIRTUS, numerical tool which enforces fl...

In dogs, diagnosis of incomplete ejaculation and azoospermia can be made by measuring the activity of the enzyme alkaline phosphatase (AP) in seminal plasma. However, even though upper cut-off value of 5000 IU/l is given in the literature, results by different assays may vary considerably. Furthermore, no data exist concerning the stability of the enzyme during storage of frozen seminal plasma,...

There are several mechanisms that affect a gas when using discharge plasma to initiate combustion or to stabilize a flame. There are two thermal mechanisms-the homogeneous and inhomogeneous heating of the gas due to 'hot' atom thermalization and vibrational and electronic energy relaxation. The homogeneous heating causes the acceleration of the chemical reactions. The inhomogeneous heating gene...

Angle-resolved x-ray photoelectron spectroscopy ( X P S ) and laserinduced thermal desorption (LD), combined with laser-induced fluorescence (LIF) detection, were used to study the etching of olycrystalline Si (poly-Si) and single crystal Si(lO0) in high density (1-2 x 10fl ions/cm3), low presswe (0.510 mTorr) C12MBr-containing, helical resonator plasmas. The XPS measurements on both unmasked S...

The plasma chemistry of fluorocarbon–oxygen–argon discharges and its influence on prominent oxygen triplets are studied. The oxygen 777 triplet is very important for the measurement of atomic oxygen in low pressure plasmas, since the 777.417 nm spectral line is frequently used for actinometry. In this paper we identify changes in the individual 777 triplet lines arising from cascade effects fro...
