2$sup 0$K vacuum pumping system for Baseball II
A vacuum pumping system that provides a cryo surface for condensing and freezing of H/sub 2/ gas is described. A closed-loop vacuum system was designed and built at Lawrence Livermore Laboratory to pump down the neutralizer LH/sub e/ dewar with a volurae of 350 l and the lambda point dewar with a LH/sub e/ volume of 250 l. Both of these dewars can be pumped down simultaneously or one at a time. 100% of the H/sub e/ gas is recovered free of contaminations. The vacuum pump can handle 340 SCFM of gas. The LH/sub e/ dewars are pumped down below the lambda point. This condition reduces the LH/sub e/ container wall temperature to 2.1 deg K giving a base pressure of 10/sup -13/ torr for H/sub 2/ gas/sup 2/. To attain a stable condition the LH /sub e/ baths are puuped down to 33 torr or lower to give a surface temperatare of about 2/sup 0/K/sup 3/. The Baseball II helium factlity is a close loop system. The H/sub e/ gas is recovered from all the LH/sub e/ usage point. This gas is accumulated in one of the two 8000 cu ft inflatable gas bags. The gas from the gas …

200 amp Neutral Beam Source
Recent efforts in controlled fusion experiments have indicated the need for large neutral-beam sources to provide an initial plasma for further plasma buildup, for use as a stoking source to makeup losses, or for plasma heating. Experiments now operating or envisioned for the near future anticipate the need for kilo-amp neutral beams in the 20-keV energy range and higher. These sources will be required to focus into relatively small-volume targets, have good gas efficiency, and use a minimum of excess gas for downstream neutralization. A test facility with sufficient pumping capacity to handle sources of this size is described. The ion source, mockup extraction grid, and the requisite electronic and power equipment for a 200-amp neutral-deuterium beam are discussed. The beam pulse length will be from 2 to 10 msec. (auth)

2XII-B pulse coil design
The design of the 2XII-B pulse coil system is presented. Development of the coil geometry is given as well as the results of magnetic field calculations. A discussion of the forces developed by this high-energy coil set and the electrical stress on the magnet insulation is presented. The results of materials selection for both the coil insulation and structure are included, and also a description of the fabrication procedure. (auth)

Absalom, Absalom! A Study of Structure
The conclusion drawn from this study is that the arrangement of material in Absalom, Absalom! is unified and purposeful. The structure evokes that despair that is the common denominator of mankind. It reveals both the bond between men and the separation of men; and though some of the most dramatic episodes in the novel picture the union of men in brotherly love, most of the material and certainly the arrangement of the material emphasize the estrangement of men. In addition, by juxtaposing chapters, each separated from the others by its own structural and thematic qualities, Faulkner places a burden of interpretation on the reader suggestive of the burden of despair that overwhelms the protagonists of the novel.

Age estimates of stratospheric air
It is shown that careful consideration of /sup 32/P//sup 7/Be ratios (both isotopes being generated in the atmosphere by cosmic radiation) not only yields information on the stratospheric or tropospheric origin of air masses. These ratios may also be used to determine the residence time in the stratosphere of tropospheric air that underwent upward transport through the tropopause and re-entered the troposphere at a later date.
