Note: Diagnostic deuterium beam with an ultra-small energy spread for plasma spectroscopy.

The DINA-5M diagnostic atomic beam has been upgraded to reduce the energy spread down to 50 eV. An active voltage stabilization system introduces a chain of varistors connected in series that can be switched with the time constant of 70 μs to minimize the deviation from the reference to the high-voltage level. Using deuterium, the enhanced diagnostic beam has the current of four atomic amperes and the energy of 50 keV ± 50 eV.

Note: Arc discharge plasma source with plane segmented LaB6 cathode.

A plane cathode composed of close-packed hexagonal LaB6 (lanthanum hexaboride) segments is described. The 6 cm diameter circular cathode is heated by radiation from a graphite foil flat spiral. The cathode along with a hollow copper anode is used for the arc discharge plasma production in a newly developed linear plasma device.

[Monitoring and prognosis of psychophysiological status and educational performance of first/second-year female medical students].

Monitoring of 28 indices in first/second-year female medical students during two years allowed to deliver the approximation of psychophysiological status and two patterns of educational performance during both session and examination period and according to them calculate the prognosis for these indices for two subsequent studying periods with high accuracy. Prognosis calculated upon the approximation and patterns would give the possibility to reveal negative impacts of stressor factors on students at the preliminary stage of the disease and to correct this condition with help of valeological programs.

[Lung functional testing by electroimpedance spirometry: experimental and clinical study].

The aim of the study was to investigate 0.9% sodium chloride saline aerosol and airways electrical impedance including experiments with plastic tubes, healthy people and asthmatic patients examination using electrical impedance spirometry. The experimental part of the study consisted of measurements of the 0.

The 25 mA continuous-wave surface-plasma source of H(-) ions.

The ion source with the Penning geometry of electrodes producing continuous-wave beam of H(-) ions with current up to 25 mA was developed. Several improvements were introduced to increase source intensity, reliability, and lifetime. The collar around the emission aperture increases the electrons filtering.
