Inertial fusion power for space applications (open access)

Inertial fusion power for space applications

More than thirty-seven design concepts have been proposed for terrestrial ICF power plants. The design space is large because of the many allowable driver and reaction chamber combinations. These design studies have illustrated advantages of ICF power plants over other sources in lower impact on the environment, high safety, and almost no dependence on consumables like fuel. The fact that, once built, a 1000 MW/sub e/ ICF power plant would require only 240 kg of deuterium and from 770 to 9260 kg of lithium to run for five years (at 70% capacity factor) makes it potentially attractive for space power also. However, the designs proposed to date have emphasized features that would make the plant attractive for terrestrial applications, where economics, efficiency, and environmental considerations dominate. The resulting plants are large and contain many very heavy components that would not be at attractive for space applications. In this paper, we evaluate alternative ICF driver and reactor technologies using space application criteria and also discuss how some of those technologies can be altered to produce smaller, lighter fusion power sources for space.

A Device for Precision Dimensional Measurement of Superconducting Cable (open access)

A Device for Precision Dimensional Measurement of Superconducting Cable

A need for continuous sampling of the dimensions of superconducting cable has lead to the development of a machine for that purpose. This device measures average thickness, width, and keystone angle for a wide variety of cable sizes while under the mechanical loading anticipated in the final coil structure. Linear dimensions can be measured to {plus minus}0.0001 in. and angle to {plus minus}0. 01{degree}. Cable can be measured with and without insulation. Loading is variable up to 25 ksi. This device has applications in epoxy free coil winding where the cable dimensions must be well understood before coil winding in order to predict the size of the finished coil package. As a diagnostic device, it has application in the cable making process to help understand causes for subtle inconsistencies in cable dimensions. A possible quality control application exists. Current cable quality control requires destructive techniques with very small samplings, usually two samples for 5000 ft of cable. We have evaluated device performance by repeated measurements of lengths of SSC cable. 7 figs.

Estimate of the Pbar Yields for the CERN ACOL Project (open access)

Estimate of the Pbar Yields for the CERN ACOL Project

For a check of the yield estimates expected for the new ACOL target station, calculations have been performed for the CERN parameters using the relatively, simple semi-analytical techniques outlined in pbar note 449. These calculations correspond to operation with a 15 cm long, 1 cm radius lithium lens at 750 T/m gradient, and a 6.5 cm tungsten production target. Comparison with the current calculated yield number for the AA with the present target station configuration (10**7 pbars per 10**13 protons, into dp/p = 1.5%) indicates an increase of a factor of 15 using the normal ACOL parameters (dp/p = 6%, a(transverse acceptance) = 240 pi mm-mrad). As explained in the report, the above lens parameters are not optimized, that is, increases in lens gradient and/or radius will result in an increase in yield, providing the corresponding changes in focal distance, beam line matching, etc. are made.
