Main fields of activity:
- Physical phenomena occurring at pulsed discharges used to produce dense magnetized plasma
- Methods and tools for diagnostics of high-temperature plasmas
- Plasma technologies
- Ion/plasma techniques in material studies
1. Physical phenomena
Experiments were carried out at our MAJA-PF facility and -- within the framework of collaboration with Institute of Plasma Physics and Laser Microfusion in Warsaw -- at their PF-1000 facility. Various diagnostic techniques were used. Microscopic irreproducibility of the so-called “hot-spots” was taken into account. In particular the following topics were studied:
- polarization of selected X-ray spectral lines
- correlation between X-rays emitted from a single hot-spot and corresponding non-thermal electron pulses
- correlation between fast neutrons, X-rays and other corpuscular emissions
- fast (ripple-born) electrons in tokamaks
2. Diagnostics
- analysis of capabilities of Cerenkov detectors based on diamond-crystal radiators
- design of measuring heads for CASTOR and TORE-SUPRA facilities
- characterization of PM-355 nuclear track detectors
- measurements of fast (>3 MeV) protons originating from D-D fusion reactions in PF-360 and PF-1000 facilities with the help of calibrated track detectors with appropriate absorption filters (using several pinhole cameras with such detectors it was possible to measure angular distribution of fusion protons and to localize fusion reaction regions)
- design and development of special ion-pinhole camera to be used for measurements of fusion-protons within TEXTOR facility in collaboration with Laboratory for Plasma Physics of the Royal Military Academy, Belgium and Institute for Plasma Physics of the Juelich Forschungszentrum, Germany
- development of optical spectroscopy methods to perform time-resolved studies of dynamics and parameters of plasma streams during their free propagation and interaction with different targets within the PF-1000 facility
- design and development of miniature Thomson-type spectrometer for measurements of ion mass- and energy-spectra.
3. Technology
- depositing thin Nb layers upon internal surfaces of RF cavities of particle accelerators (in collaboration with Tor Vergata University, Italy):
- stabilization and reduction of arc discharge current at ultra-high vacuum
- influence of residual gases
- prototype of cylindrical magnetic filter for the linear-cathode system
- different types of magnetic filters for the planar-cathode system
- depositing thin Pb films to form Pb cathodes within RF electron guns
- dynamics of plasma discharges in IPD-type accelerators
- plasma-ion techniques for material engineering
