Brick-wall at high energy from trapped electrons in a dc beam (open access)

Brick-wall at high energy from trapped electrons in a dc beam

The space charge detuning of a dc beam due to electrons trapped is shown to be essentially energy independent. This leads to a curvature in the ..nu.. vs p relation. Left uncorrected, this would result in a "brick-wall" instability. It is shown that the strength of octupole field required to correct the curvature increases as the third power of the energy. Thus, large octupole correction coils are needed. The possibility of using stronger sextupole corrections to reduce the octupole requirement is suggested. However, this would mean that the working line would not shrink with energy, and ISABELLE would be required to operate with a tune spread greater than or equal to 0.02 even at 400 GeV.

Summary of climatic input for waste management site suitability criteria and state of progress (open access)

Summary of climatic input for waste management site suitability criteria and state of progress

Because groundwater movement can have important effects on buried nuclear wastes, hydrologists need to know if future climatic changes will influence the accuracy of groundwater flow calculations. Groundwater recharge (and therefore groundwater flow) depends on surface water balance. (Surface water balance equals precipitation less losses to evaporation, runoff, and storage.) To develop input data for modeling future climatic effects, we have made the following simplifying assumptions: (1) Climate (and therefore water balance) will behave in the future very much as it has in the past. (2) Groundwater recharge responds linearly to precipitation. (3) Future long-term climatic changes can be classified into groups or regimes that are similar to those of the past. Our current research is aimed at providing input data to the Waste Management Program's site suitability task. 16 figures, 1 table.
