    “…Charge, fired strip multiplicity and arrival time distributions for the induced signal were investigated for the $2 ~mm$ gap RPC operating with several tetrafluoroethane ($C_{2}H_{2}F_{4}$) based mixtures with variation of isobutane ($iC_{4}H_{10}$) and sulphur hexafluoride ($SF_{6}$) concentrations. Suppression of the large fast charges for the mixtures containing $SF_{6}$ in comparison with the binary $C_{2}H_{2}F_{4}$/$iC_{4}H_{10}$ mixture was confirmed. …”

    “…We discuss several plasma techniques for surface fluorination: deposition of fluorocarbon thin films either by magnetron sputtering of polytetrafluoroethylene targets, or by plasma-assisted chemical vapor deposition using tetrafluoroethane as a precursor, and modification of carbon nanowalls by plasma treatment in a sulphur hexafluoride environment. We showed that conformal fluorinated thin films can be obtained and, according to the initial surface properties, superhydrophobic surfaces can be achieved.…”
