    Notes: The Advanced Toroidal Facility (ATF) [Fusion Technol. 10, 179 (1986)] is the world's largest stellarator. It was designed and built to demonstrate high beta, steady-state operation in a toroidal confinement system. During its final operating period ATF achieved pulse lengths of over one hour (4667 s). The objectives of these experiments were (1) investigation of plasma performance at times that are long compared to the plasma/wall equilibrium time; (2) determination of plasma control and wall conditioning techniques; and (3) adaptation of plasma diagnostic and data acquisition systems to long-pulse operation. Other experiments have also extended earlier studies of dimensionless-parameter plasma confinement scaling. By employing two discrete electron cyclotron heating (ECH) frequencies (28 and 35 GHz), and by simultaneously modulating the ECH power, magnetic field, and plasma density, it has been possible to maintain fixed plasma beta and collisionality while modulating the normalized gyroradius. © 1995 American Institute of Physics.

    Notes: [Auszug] As Prof. Compton points out, the phenomena relating to the forward directed β-ray tracks of short range, which appear in air exposed to X-rays of short wave-length, are in agreement with his suggestion that scattering of a quantum may be effected by a single electron. That the phenomena ...

    Notes: [Auszug] I DO not think that any worker with ions or with condensation nuclei who may have read the papers on “Experiments with Ionised Air” and on “The Structure of the Nucleus” will consider my criticism unjust. The latter part of the letter requires some reply. According to Prof. Barus, in all ...

    Notes: [Auszug] IN a letter on this subject in NATURE of March 29, Mr. Aitken criticises the theory which attributes the prevalence of positive electrification in the atmosphere to the superiority in efficiency as nuclei for the condensation of water vapour, of the negative ions over the positive. That ...
