Abstract
Ova disertacija bavi se dijagnostikom atmosferskog plazmenog mlaza koji pripada širokoj grupi hladnih neravnotežnih plazmi. U tu svrhu razvijen je eksperimentalni uređaj za generaciju visokonaponskih DC pulseva koji uzrokuju paljenje izboja na repeticiji od nekoliko kiloherca. Slobodni plazmeni mlaz karakteriziran je posredstvom optičke emisijske spektroskopije i mjerenjem struje izboja. Laserskom apsorpcijskom spektroskopijom u optičkom rezonatoru istražen je utjecaj različitih meta na koncentraciju atoma helija u metastabilnom stanju. Razvijen je eksperimentalni postav koji omogućava proučavanje međudjelovanja laserski inducirane plazme i plazmenog mlaza. Istraženi su efekti predionizacije na paljenje laserski inducirane plazme, te su napravljena prostorno razlučiva emisijska mjerenja i mjerenja za različita vremena kašnjenja između laserskog i naponskog pulsa. Predložena je nova eksperimentalna tehnika za dijagnostiku plazmenog mlaza, ali i ostalih tipova hladne plazme. Napravljena su emisijska mjerenja za vrijeme kontakta plazmenog mlaza i vode, te je istražen utjecaj plazmenog mlaza na pH vrijednost tretirane vode.
Abstract (english)
This dissertation deals with diagnostics of atmospheric pressure plasma jet which belongs to a group of cold nonequilibrium plasmas. To that purpose, an experimental device has been developed for the generation of high voltage DC pulses used for repetitive (kHz) discharge ignition. Free plasma jet was characterised by means of optical emission spectroscopy (OES) and electrical measurements. Influence of different targets on helium metastable concentrations was investigated by means of cavity ring-down spectroscopy. Experimental setup that enables study of laser induced plasma interacting with the plasma jet was developed. Effects of preionisation on the ignition of laser induced plasma were investigated, as were effects of spatial coupling and synchronisation of laser and high voltage pulse by means of OES and absorbed energy measurements. A new experimental technique was proposed for the diagnostics of plasma jet and other types of cold plasma. OES measurements were performed during the interaction of the plasma jet with the water target and the pH value of the plasma treated water was measured for different treatment parameters.
