Transistor Driven Beam Switching Tube Decade Counter

Abstract: "This paper describes an electrical readout, decade counter employing the magnetron beam switching tube with transistor drive. Double pulse resolution is one microsecond. The unit will accept a variety of transistor types and will tolerate supply voltage variations of +/- 20% at ambient temperatures up to 60 C. A "Pixie" neon indicator is driven without the use of additional transistors. A readout circuit for printer on punched paper tape is presented."

Rupture Potential and Axial Power Distribution (open access)

Rupture Potential and Axial Power Distribution

This report gives results of a study of the effect of changes in axial power distribution on rupture potential. Possible interrelationships between this effect and the effects of other reactor variables were investigated.

Two-Liquid-Phase Temperature Limits for the Homogeneous Reactor Fuel Solution and Its Concentrates: Comments on Solid-Liquid Equilibria (open access)

Two-Liquid-Phase Temperature Limits for the Homogeneous Reactor Fuel Solution and Its Concentrates: Comments on Solid-Liquid Equilibria

Temperatures are given at which two liquid phases form in a synthetic homogeneous reactor fuel solution and its concentrates. The data show a two- liquid-phase boundary temperature of 332 deg C for the particular HRT fuel composition and a flat minimum temperature of 305 deg C for the initial solution concentrated between 6 and 16 times. Experiments on solid-liquid equilibria between 300 and 329 deg C are presented to indicatc sclution stability in this temperature region. Some related comments on current HRT operation are given.

Transistor Driven Beam Switching Tube Decade Counter

An electrical readout, decade counter employing a magnetron beam switching tube with transitor drive is described. Double pulse resolution is one microsecond. The unit will accept a variety of transitor types and will tolerate supply voltage variation of plus or minus 20% at ambient temperatures up to 60 deg C. A neon indicator is driven without the use of additional transitors. A readout circuit for printer on punched paper tape is presented. (auth)

Cofit - A 709 Program for Determining Extrapolation Length from Horizontal Traverse Data (open access)

Cofit - A 709 Program for Determining Extrapolation Length from Horizontal Traverse Data

A program has been prepared for the 709 computer which will determine extrapolation length from horizontal traverses measurements taken in an exponential pile. The flux across the pile is assured to fit a cosine function of the form y = A cos B (X-C)
