2$sup 0$K vacuum pumping system for Baseball II

Description: 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 … more

200 amp Neutral Beam Source

Description: 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… more

2XII-B pulse coil design

Description: 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)

Age estimates of stratospheric air

Description: 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.

Aluminum etchant control study

Description: Studies of ferric chloride-phosphoric acid--water solutions used for etching precision patterns in aluminum foil resulted in reliable analysis procedures for detecting solution depletions. Replenishment of the etchant on a regular basis using specified guidelines has been shown to increase its effective life and produce more consistent quality than previous attempts at solution control.

Application of ideal reactors to studies in atmospheric chemistry

Description: Mass-transfer effects and surface reactions may severely obscure the observation of homogeneous chemical reaction rates from experimental reactor data. Such problems are particularly pertinent to studies in the atmospheric sciences, owing to the tendency for increased surface-reaction interference at the low concentrations usually of interest. Criteria are presented for ideal behavior in three basic types of experimental reactors. Under conditions satisfying these criteria the effects of compet… more
