This report contains the results of calculations for a resized nozzle on the D-Zero test cryostat. The nozzle neck in the inner vessel with be 6-inch schedule 10S pipe and 8-inch 10S will be used for the outer vessel. On top of the nozzle will be placed the D-Zero Endcap Calorimeter signal board feedthru dewar box. This box weighs approximately 250 lbs but the weight was conservatively taken to be 500 lbs. The allowable pressure from above does not exceed 15 psig per ASME, but it does exceed 7.5 psig required by CGA-341 therefore reinforcement is not required. Note that the reinforcement provided by the nozzle neck in combination with the excess shell thickness is probably sufficient to satisfy the ASME requirements.

In the last few years the development of tandem-discharge hydrogen-negative-ion-source systems has proceeded along both experimental and theoretical lines. To some extent these developments have proceeded independently, either the available theoretical model was inadequate to account for a specific geometrical configuration, or the experimental data was not sufficient to provide adequate input parameters for calculation. In the tandem system described here the electron temperature, electron density, and other relevant parameters have been obtained for a high-density system whose electron densities range up to 3 - 5 x 10/sup 12/ electrons cm/sup -3/. The model calculation for the atomic processes has been extended to include both electron density and electron temperature spatial variations through the second chamber. These spatial variations are essential for an adequate interpretation of tandem systems where steep density gradients may occur beyond the magnetic filter region. In this paper we shall combine the experimental density data with the new spatially dependent atomic model for the purpose of attempting a correlation of the observed and calculated current densities. 9 refs., 8 figs., 3 tabs.

We discuss the acceleration of magnetically-confined plasma rings to provide a driver for ICF. The acceleration of plasma rings is predicted to be efficient and following focusing, to generate ion-bombardment power in the range 10/sup 15/ to 10/sup 16/ W/cm/sup 2/ at a total deposition energy of multimegajoules. The simplicity of plasma ring accelerator suggests that a 5 MJ (on target) driver would cost in the range 1 to 5 $/joule. First experimental tests of the accelerator are described.
