Aims of the course | Bring students closer to working in scientific laboratories that exist at the faculty through the experimental methods used in them. The course is designed so that students with a level of knowledge of general physics courses can take it without much effort. Students will be introduced to similar experiments in the world. | |||||||||
Learning outcomes | Adopting basic concepts related to modern experiments in physics. Preparing students for using modern diagnostic methods. | |||||||||
Contents of the course | ||||||||||
Lectures | 1.
Electric gas discharge (basic concepts, glow discharge, corona, barrier
discharge, plasma compressors, measurement of gas discharge electrical
parameters). 2. Optical detectors (photodiode, photomultiplier, CCD, detector sensitivity, lock-in amplifier). 3. Spectroscopic instruments (spectral regions, dispersion elements, calibration of spectrometers). 4. Spectroscopic measurement of temperature (theoretical bases and measurement of excitation temperature using the Boltzmann plot). 5. Application of barrier discharges (absorption measurement of ozone concentration). 6. Semiconductor diode laser (theoretical bases and measurement of electrical and optical characteristics of the laser diode). 7. Optogalvanic spectroscopy and Laser Induced Fluorescence (LIF). 8. Plasma interaction with surfaces of different materials. 9. Fundamentals of diagnostic techniques for treated materials (microscopy - SEM, AFM, XRD; ATR FTIR) and practical application on treated samples. 10. Laser-produced plasma. 11. Wind tunnel. |

Examples/ practical classes | Experimental
exercises are adapted to the subject of physics research at faculty. Students
will most of the time carry out experimental exercises alone, but with the
obligatory attendance of teachers. 1. Measurement of electrical parameters of gas discharges. 2. Measurement of sensitivity of optical detectors. 3. Lock-in amplifier and its use in optical and electrical measurements. 4. Wavelengths and intensity calibration of the spectrometer with diffraction grating 5. Recording of optical spectra of Geissler tubes, spectral line identification and spectroscopic measurement of plasma temperature. 6. Measurement of ozone concentration by absorption of continuous ultraviolet radiation. 7. Determination of the composition of gases using the FTIR spectrometer 8. Measurement of the electrical and optical characteristics of the laser diode. 9. Demonstration of optogalvanic effect and laser induced fluorescence. 10. Plasma-thruster interaction with surfaces of different materials; diagnosis of treated materials using SEM and XRD. 11. Demonstration of experiment with laser-produced plasma. 12. Measurements in the wind tunnel. 13. Introduction to other scientific experiments carried out at the faculty. |
