Work on thc B-3 stellarator is reported in which it was found that adding helical stabilizing winding, which should in theory produce complete stability produced no discernible change on the observed pump-out rate. The statistical properties of such fluctuations as the reduction of the pump-out rate when the aperture is reduced by a limiter and the marked differcnce between the results on Etude with an unbaked vacuum system) and B-3 are discussed. The B-1 device magnetic probes were used to measure fluctuations of the stellarator magnetic field. B-65 optical obscrvations confirm that ion-cyclotron resonance waves heat primarily the outer regions of the discharge. An extensive theoretical investigation of confinement in the stellarator led to a number of basic problems in particle dynamics such as constancy of the longitudinal adiabatic invariant, which was proved to all orders. Preliminary results indicate that confinement of single particles in the stellarator geometry can be easily achieved if the magnetic and electric fields are constant in time.
