[en] Nuclear thermoelectric units with electric power as high as 200 KWT, in case of of lifted thermogenerator blocks by their technical, ecological, and economic chracteristics, meet the requirements of autonomous electric energy sources for land-based and sea units of the stationary and transportable type. This report describes the developement of a thermoelectric unit with two phase thermosiphons in the cooling circuits
[en] Nuclear thermoelectric units meet the requirements of autonomous electric energy sources for land-based and sea units of the stationary and transportable type. This report describes the lay-out of a nuclear thermoelectric station as a power source for remote, sparsely populated areas
[en] This paper presents a method for improving the accuracy of space-charge computation for electron-optical systems. The method proposes to divide the computational region into two parts: a near-cathode region in which analytical solutions are used and a basic one in which numerical methods compute the field distribution and trace electron ray paths. A numerical method is used for calculating the potential along the interface, which involves solving a non-linear equation. Preliminary results illustrating the improvement of accuracy and the convergence of the method for a simple test example are presented.
[en] An experiment on generation and transmission of an intensive electron beam through a magnetic mirror has been carried out at the GOL-3 magnetic trap. An adapted theory and numerical modelling were used to find a maximal beam current for which no beam electrons are reflected. The effect of space charge and magnetic mirror of the reflection were taken into account. A comparison of the computed limiting current with experimental value allowed us to validate a hypothesis that the appearance of reflected electrons is responsible for electric breakdown in the electron gun.
