Planning for the next generation of standard electronics
Recommendations of a committee for a new standard to meet needs of new high-energy physics experiments are summarized in a nontechnical manner. Existing standards, including CAMAC, were examined; it was felt that none would meet the future needs of high-energy physics. The original committee gave its recommendations and disbanded. The design committee has begun its work; it anticipates finishing in about two years, in time for application of its recommendations to ISABELLE. (RWR)

Advanced-fueled fusion reactors suitable for direct energy conversion. Fourth quarterly progress report: October 1976--December 1976 and first quarterly progress report: January 1977--March 1977
The direct energy conversion efficiencies calculated for Cat-D and D-/sup 3/He fueled Tokamak reactors are summarized over a range of reactor designs, collector configurations, assumed T/sub e//T/sub i/ ratios, and power densities. The performance of a system of superconducting coils that produce those fields required to guide escaping plasma along the path between the bundle divertor coils and the direct converter is also discussed.

Efficiency improvements in pipeline transportation systems
This report identifies potential energy-conservative pipeline innovations that are most energy- and cost-effective and formulates recommendations for the R, D, and D programs needed to exploit those opportunities. From a candidate field of over twenty classes of efficiency improvements, eight systems are recommended for pursuit. Most of these possess two highly important attributes: large potential energy savings and broad applicability outside the pipeline industry. The R, D, and D program for each improvement and the recommended immediate next step are described. The eight technologies recommended for R, D, and D are gas-fired combined cycle compressor station; internally cooled internal combustion engine; methanol-coal slurry pipeline; methanol-coal slurry-fired and coal-fired engines; indirect-fired coal-burning combined-cycle pump station; fuel-cell pump station; drag-reducing additives in liquid pipelines; and internal coatings in pipelines.

Numerical study of particle motion in two waves
One studies the dynamical system described by the Hamiltonian H = H/sub 0/ + EPSILON V, where H/sub 0/ = /sup 1///sub 2/ p/sup 2/ - cos x, V = - cos (lambda x - ..cap omega..t). One encounters this system in a number of problems of practical importance. In addition, the system has intrinsic interest for the theory of adiabaticity and stochasticity. The invariant action J of the unperturbed Hamiltonian H/sub 0/ is subject to strong modification or destruction because of the perturbation EPSILON V. Absence of an invariant (i.e., stochasticity) occurs in a phase space region whose size and shape vary with the three parameters EPSILON, lambda, ..cap omega... Previous studies have varied the amplitude of a perturbation (our epsilon); one emphasizes the strong dependences on the space (lambda) and time (..cap omega..) scales of the perturbation. Results show that a perturbation is most effective at causing stochastic motion if its space and time scales are comparable (lambda - 1, ..cap omega.. - 1) to those in the unperturbed Hamiltonian H/sub 0/.

Unsteady jet-slug dynamics. [BWR]
The present analysis treats the transient load characteristics at the wet-well bottom during the vent-clearing event under loss-of-coolant accident conditions. A conceptual model is introduced wherein the liquid-jet inertia and the net momentum-efflux are the two dominant physical factors. The derived load-history equations were found to be functions of the vent-clearing characteristics and of the jet-decay mode in the liquid pool. The theoretical results obtained by a physical modelling of these phenomena appear to agree reasonably well with the available data from UCLA and from LLL /sup 1///sub 5/-scale experiments.
