From 3rd international symposium on toroidal plasma confinement; Garching, Germany (26 Mar 1973). The collisional plasma containment time was studied as a function of plasma parameters in the wide range of collision frequency. Experimental dependences are shown not to coincide with the conclusions of the neoclassical theory. Particle-containment time was investigated as a function of the parameters which, according to the theory, are responsible for the diffusion. Plasma was produced by laser injection. This method allowed the change of plasma parameters in the following ranges: n(e) from 5 x 10/sup 10/ to 10/sup 12/ cm/sup T(e) from 0.3 to 3 eV, T(i) from 5 to 60 eV. Plasma consisted mainly of singly ionized lithium, the neutral lithium density amounting to 10/sup -3/ of plasma density. The containing magnetic field was changed from 4 to 12 kG. (GE)
