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.

Charged particle fusion targets. [Energy requirements for inertial confinement fusion]
The power, voltage, energy and other requirements of electron and ion beam fusion targets are reviewed. Single shell, multiple shell and magnetically insulated target designs are discussed. Questions of stability are also considered. In particular, it is shown that ion beam targets are stabilized by an energy spread in the ion beam.

Cladding creepdown under compression. [BWR; PWR]
Light-water power reactors use Zircaloy tubing as cladding to contain the UO/sub 2/ fuel pellets. In-service operating conditions impose an external hydrostatic force on the cladding, causing it to creep down into eventual contact with the fuel. Knowledge of the rate of such creepdown is of great importance to modelers of fuel element performance. An experimental system was devised for studying creepdown that meets several severe requirements by providing (1) correct stress state, (2) multiple positions for measuring radial displacement of the cladding surface, (3) high-precision data, and (4) an experimental configuration compact enough to fit in-reactor. A microcomputer-controlled, eddy-current monitoring system was developed for this study and has proven highly successful in measuring cladding deformation with time at temperatures of 371/sup 0/C (700/sup 0/F) and higher, and at pressures as high as 21 MPa (3000 psig).

pi. pi. scattering by pole extrapolation methods. [2. 67 GeV/c, angular distribution, Chew-Low and Durr-Pilkum methods, OPE model, isospin]
A 25-inch hydrogen bubble chamber was used at the Lawrence Berkeley Laboratory Bevatron to produce 300,000 pictures of ..pi../sup +/p interactions at an incident momentum of the ..pi../sup +/ of 2.67 GeV/c. The 2-prong events were processed using the FSD and the FOG-CLOUDY-FAIR data reduction system. Events of the nature ..pi../sup +/p ..-->.. ..pi../sup +/p..pi../sup 0/ and ..pi../sup +/p ..-->.. ..pi../sup +/..pi../sup +/n with values of momentum transfer to the proton of -t less than or equal to 0.238 GeV/sup 2/ were selected. These events were used to extrapolate to the pion pole (t = m/sub ..pi..//sup 2/) in order to investigate the ..pi.. ..pi.. interaction with isospins of both T = 1 and T = 2. Two methods were used to do the extrapolation: the original Chew-Low method developed in 1959 and the Durr-Pilkuhn method developed in 1965 which takes into account centrifugal barrier penetration factors. At first it seemed that, while the Durr-Pilkuhn method gave better values for the total ..pi.. ..pi.. cross section, the Chew-Low method gave better values for the angular distribution. Further analysis, however, showed that if the requirement of total OPE (one-pion-exchange) were dropped, then the Durr-Pilkuhn method gave more reasonable values of the …

Evaluation of the photochemical production of hydrogen from solar energy
The potential for utilizing solar energy through photochemical storage were investigated. Both water and nitrosyl chloride systems are examined. A comprehensive review of the literature led to the conclusion that many major questions must be answered before photochemical energy storage becomes a viable alternate means of exploiting solar energy.

Radioactive liquid wastes discharged to ground in the 200 Areas during 1976
An overall summary is presented giving the radioactive liquid wastes discharged to ground during 1976 and since startup (for both total and decayed depositions) within the Production and Waste Management Division control zone (200 Area plateau). Overall summaries are also presented for 200 East Area and for 200 West Area. The data contain an estimate of the radioactivity discharged to individual ponds, cribs and specific retention sites within the Production and Waste Management Division during 1976 and from startup through December 31, 1976; an estimate of the decayed activities from startup through 1976; the location and reference drawings of each disposal site; and the usage dates of each disposal site. The estimates for the radioactivity discharged and for decayed activities dicharged from startup through December 31, 1976 are based upon Item 4 of the Bibliography. The volume of liquid discharged to the ponds also includes major nonradioactive streams. The wastes discharged during 1976 to each active disposal site are detailed on a month-to-month basis, along with the monthly maximum concentration and average concentration data. An estimate of the radioactivity discharged to each active site along with the remaining decayed activities is given.

High-voltage test stand at Livermore
This paper describes the present design and future capability of the high-voltage test stand for neutral-beam sources at Lawrence Livermore Laboratory. The stand's immediate use will be for testing the full-scale sources (120 kV, 65 A) for the Tokamak Fusion Test Reactor. It will then be used to test parts of the sustaining source system (80 kV, 85 A) being designed for the Magnetic Fusion Test Facility. Following that will be an intensive effort to develop beams of up to 200 kV at 20 A by accelerating negative ions. The design of the test stand features a 5-MVA power supply feeding a vacuum tetrode that is used as a switch and regulator. The 500-kW arc supply and the 100-kW filament supply for the neutral-beam source are battery powered, thus eliminating one or two costly isolation transformers.
