From 3rd international symposium on toroidal plasma confinement; Garching, Germany (26 Mar 1973). The lack of a theory of diffusion in stellarators explains the interest in experimental studies of a low-collision- frequency plasma confinement. Such experiments offer the possibility to model and to investigate some peculiarities of a high-temperature plasma confinement. The titanium plasma source was used for the experiments on the toroidal l = 3 Saturn-1'' torsatron. Plasma density measurements were made using a single Langmuir probe and a multimode resonator method. The plasma confinement time was measured 5 msec after injection at electron density equal to 5 x 10/sup 8/ cm/sup -3/. Electron and ion temperature, measured with a single and multigrid probe, were approx equal 8 and 20 eV, respectively. The results show a continuation of a plateau coefficient'' diffusion to the banana region. This is in qualitative agreement with measured values of the radial electric field. (GE)
