When particle physics is a closed subject which has been condensed into a text book, the material will surely be organized by concepts and not according to what fact was learned on what accelerator. But short of that day facilities must be designed, planned, and developed, and experiments must be executed on one of a number of available accelerators; and a very necessary point of view is to ask what physics can be done with one facility, in contrast to another. It is in this spirit that, in this note, we look at electron colliding beam devices. In the first section we discuss the physics that can be done with colliding electron beams. After some general remarks we review the experiments already performed, and then turn to experiments planned for the future. The physics that can be done with any accelerator is a strong function of the physics of the accelerator. Every reader of this Journal knows what determines the energy of an accelerator, but the physics that determines the beam intensity, quality, and pulse length is perhaps not so well known. In fact, we plan to devote a future Comment to the physics that limits the performance of conventional …

The purpose of this memorandum is to provide interim limits for a lower sodium dichromate feed to reduce water treatment costs. The interim limits are a function of exit water temperature and pH. The process standards will be revised when current studies on the effects of dichromate reduction are completed.

This document is the January 1969 monthly report for Hanford Categories C-57 and C-65. It covers reactor plant operation, fuel and target fabrication, irradiation services, and technical activities at the Hanford C, N, and K reactors. It features an evaluation of an incident at the KW reactor.

This report addresses the crystal geometry and mechanisms of phase transformations in crystalline solids.

Cobalt irradiations were completed in two C-Reactor overbore tubes in support of Mission and Program investigations of isotope production. Tubes 1459 and 464 were each charged with approximately 4015 grams of cobalt in strips similar to BNL pieces described in a separate report. After discharge, the strips were placed in an underwater calorimeter to determine the heat contribution from isotopic decay, thereby allowing an assay of cobalt-60 concentrations. The cobalt-60 produced in tube 1464-C was retained by Douglas United Nuclear for source material in an underwater gamma irradiator at KE-Reactor; the remaining cobalt, from tube 1459-C, was shipped to Battelle-Northwest for further experiments and applications. A total of 396,400 Ci of cobalt-60 was produced in tube 1459-C and 272,700 Ci in tube 1464-C during the irradiations. Production in tube 1459-C occurred at the rate of 0.637 Ci/gm per 100 MWd/T of adjacent tube power; production in tube 1464-C occurred at the rate of 0.670 Ci/gm per 100 MWd/T of adjacent tube power. The total irradiation time was 880.813 full power days for tube 1459-C and 569.010 full power days for tube 1464-C.
