Diffusion losses of ions and electrons in the ''Jupiter-1A'' electromagnetic trap

Electron and ion diffusion currents out of an electrmagnetic trap were investigated. Diffusion losses of electrons along the magnetic field amounted to 3-30% of an integral electron losses and decreased exponentially with the cutoff voltage increase. The transverse diffusion of low-energy electrons trapped in the line cusp area is the main part of an electron loss. Characteristic frequency of this process is of the same order of magnitude as an electron-ion collision frequency. Ion losses through the line cusp are the main part of integral ion losses. Anomalous transverse diffusion losses were in near-axial area. The transverse ion losses accounted for a considerable part (25%) of integral losses
