Abstract

Summary form only given. The gas dynamic trap (GDT) is an axisymmetric open trap with a large mirror ratio and a length greatly exceeding the ion mean free path of scattering into the loss cone. We studied axial energy and particle losses from the trap and their dependencies upon the plasma parameters inside the central cell. In these experiments the central cell density was in the range of 1-1.5/spl times/10/sup 13/ cm/sup -3/, the electron temperature was up to 25 eV (the ion temperature is believed to be the same). Under these conditions the ion mean free path was greater than the length of the mirror so as the regime of the plasma outflow through the mirrors was collisionless.
