Study of the Chemical Oxygen-iodine Laser with the production of atomic iodine from gaseous compounds
Picková, Irena ; Tichý, Milan (advisor) ; Čada, Martin (referee) ; Krčma, František (referee)
This work deals with the study of dissociation of iodine molecule for Chemical and Discharge Oxygen-Iodine Laser. Chemical way of HI dissociation and discharge way of dissociation of CH3I and CF3I molecules is examined. Main diagnostics method is absorption spectroscopy. Part of the work is also the modeling of system of chemical reactions. Last part of this work is dealing with the study of plasma generated by the radiofrequency generator in the hollow cathode plasma jet system using argon or mixture of argon with iodine. Diagnostic method used is Langmuir probe.
Study of reactions of simple ions in low temperature plasma
Kálosi, Ábel ; Plašil, Radek (advisor) ; Picková, Irena (referee)
The subject of this thesis is the study of the probe diagnostic method of low temperature plasma. The basis of Langmuir probe diagnostics in terms of appli- cation on apparatus CryoFALP II for the study of reactions of simply particles, the principle of the FALP technique and the experimental method of undertaken measurements are described. As a part of the thesis a package of evaluation pro- grams were compiled, which are ready to be a part of the measuring system as described in the thesis. Main results concern verification of the proper application of Langmuir probe technique in conditions characteristic for the apparatus, argon plasma was chosen as the medium of the measurements, where the characteristic loss process is ambipolar diffusion of charged particles. The application of the acquired knowledge is shown on recombination in oxygen plasma.
Produkce atomárního jódu
Picková, Irena ; Jirásek, Vít ; Schmiedberger, Josef
In this article we describe our new experimental device for generation of atomic iodine in discharge for a COIL (chemical oxygen-iodine laser) and also DOIL (discharge oxygen-iodine laser) systems. For the new discharge method of atomic iodine generation, we are going to use the optical emission spectroscopy diagnostics, by which we will detect species present in plasma and use this information for optimization of iodine generation process.
Study of gas reactions in a chemical oxygen-iodine laser

Experimentálně a teoreticky byly studovány chemické metody produkce atomárního jódu pro chemický kyslík-jodový laser (COIL) z plynných reakčních složek reakcemi atomů chloru nebo fluoru s jodovodíkem. Obě metody poskytují po optimalizaci produkčních podmínek vysoké výtěžky a koncentrace jódu, které jsou dostatečné pro účinnou laserovou generaci v COIL. Zásadním předpokladem pro velké laserové zesílení je zamezení reakce mezi singletovým kyslíkem a jodovodíkem, která vede k jeho zhášení na základní stav. Reagující i nereagující proudění plynu bylo modelováno pomocí kvazi-1D a CFD výpočtů.
