Aims of the course | Introduce students to work in the Faculty’s scientific laboratories through experimental methods that are used in them. The course is designed in such way that students with the knowledge of the general physics courses can adopt it without much effort. Students will be informed about similar experiments are performed in the world. | |||
Learning outcomes | The adoption of the basic concepts related to current experiments in physics. Preparing students for the use of modern diagnostic methods. | |||
Contents of the course | ||||
Lectures | 1. Electric gas discharge (basic concepts, glow discharge, corona, barrier discharge, plasma compressors, measurement of electrical parameters of gas discharges). 2. The optical detectors (photodiodes, photomultiplier, CCD, measuring the detector sensitivity, lock-in amplifier). 3. Spectroscopic instruments (the spectral region, dispersion devices, calibrations of spectrometers). 4. Spectroscopic measurement of temperature (theoretical basis and measurement of electron excitation temperature using Boltzmann plot). 5. Applications of barrier discharges (the ozone concentration by absorption measurement). 6. The diode laser (theoretical basis and measurement of electrical and optical characteristics); 7. optogalvanic spectroscopy and laser induced fluorescence (LIF). 8. The interaction of the plasma flow with the surfaces of various materials. 9. Fundamentals of diagnostic technique for treated material (microscopy - SEM, AFM, X-ray-structural analysis - XRD, FTIR). 10. The laser produced plasma. 11 Wind tunnel. | |||
Examples/ practical classes | Laboratory
course are designed according to the scientific experiments being studied at
the faculty. Students will run their own experimental work but with the
necessary presence of the teacher. 1. Measurement of the gas discharge electrical parameters. 2. Measurement of optical detectors sensitivities. 3. Lock-in amplifier and its use in optical and electrical measurements. 4. Calibration of the spectrometer with a diffraction grating - wavelength and intensity. 5. Recording of optical spectra of Geissler tubes, identification of spectral lines and spectroscopic measurement of plasma temperature. 5. Measurement of the concentration of ozone by absorption of continuous ultraviolet radiation. 6. Determination of the composition of gases using FTIR spectrometer 7. Measurement of electrical and optical characteristics of the laser diode. 8. Demonstration of optogalvanic effect and laser-induced fluorescence. 9. The interaction of the plasma flow with the surface of various materials; Diagnostics of treated samples using SEM and XRD.10. Demonstration experiment with laser-produced plasma. 12. Measurements in the wind tunnel. 13. Introduction to other scientific experiments at the faculty. |
