The Polywell is a magnetic version of a Spherically Convergent Ion Focus (SCIF) device which was proposed as a significant variation of earlier studies on electrostatic confinement. The idea of this device is to inject high energy electrons into a quasi-spherical magnetic field; the electrons create a potential well of sufficient depth to accelerate ions from low energy at the periphery to fusion energies within a focus at the center ...
Much progress was made in characterizing the principal plasma physics phenomena involved in the plasma 3 wave mixing scheme under experimental investigation by Dr Bob Schumacher of Hughes Research Labs. Bennett pinching was found to be extremely important in focussing the counterstreaming electron beams in the device. The ion modulation instability was identified as the crucial remaining issue to be studied for improving the signal purity of this millimeter wave ...
Dynamic mechanical analysis was performed on a variety of temperature resistant polymers and composite resin matrices. Data on glass transition temperatures and degree of cure attained were derived. In addition a laboratory based computer system was installed and data base set up to allow entry of composite data. (Author, modified).
A test program was conducted to develop mechanical strength data on ECDE 7581 glass fabric impregnated with F161 resin. This data is to be used in the new revision of MIL-HDBK-17. The properties determined were tensile, compressive and shear strengths and stiffnesses and Poisson's ratios over the temperature range of -65F to 450F. The results are presented in graphical, tabular, and summary forms. (Author)
