Syllabus of lectures:

1.Measurement of current and voltage .

2.Detection of X-ray emission. X-ray optics, filters, detectors, X-ray and XUV spectroscopy, different types of spectroscopes.

3.Atomic and radiate physics (elementary processes, radiate transport) spectroscopic methods of determination of plasma parameters. Models LTE, collision-radiate, coronal and non-stationary; conditions and criteria.

4.X-ray spectroscopy with temporal, space and spectral resolution, PIN detectors, polychromators, pinhole cameras, MCP detectors, streak cameras, bolometry, tomography.

5.Pulse laser as the active diagnostics of measurement of densities and their gradients, Interferometry, schlieren and shadow methods, Thomson scattering.

6.Practical measurements.

7.Langmuir probe measurements .

8.Microwave diagnostics, analysis of spectra by FFT .

9.Beams of neutral particles as the active diagnostics, detection of neutral particles .

10.Diagnostics of plasma interaction with the wall .

11.Detection of high-energy electrons, ions and photons with temporal, space and energy resolution.

12.Detection of fusion neutrons with temporal, space and energy distribution.

13.Time-of-flight and MC analysis of neutron signals, methods of reconstruction of signals and determination of temporal evolution of energy spectrum.
