A Wide-Range Neutron Detector and Monitoring Instrument : Final Report

Description: This is the final report on the progress, "A Wide-Range Neutron Detector and Monitoring Instrument," ARF 1118-6. This report covers activities from May 8, 1958 to May 8, 1959. This report describes the basic design principles of a proportional counter that has been constructed whose cathode diameter increases towards one end.

An Improved Nuclear Measuring Principle : Quarterly Progress Report No. 3 Covering the Period from December 1, 1959 to March 1, 1960

Description: This report is the third in a series of quarterly reports discussing the concept and progression of an improved method in nuclear measuring than the usage of the scintillation counter. This report indicates that in a chopped double beam system, commutation of the detector current permits selection of optimum response time and size of radioactive sources.

Research Study on Neutron Interactions in Matter as Related to Image Formation

Description: From abstract: "In this report we present data obtained with the optical simulation apparatus on image quality as a function of the parameters of neutron scattering and image detector resolution...Also included in this report is a brief description of a large area (5 inch diameter) neutron beam exposure facility being set up at the reactor for the phase three work."

In Situ Tracers Project Second Quarterly Progress Report: June-August 1959

Description: The purpose of this program is to summarize and evaluate the potential usefulness of in situ tracers, design and construct prototypes of large low-level soft beta counters for industrial application, especially of such isotopes as carbon-14 and tritium, and design and construct a prototype of a large low-level liquid scintillation detector for use vi the process gamma counting.

Transistors: Counters

Description: Abstract: "Two transistor plug-in decade counters are described, one of which operates over the SCS-7 temperature range. A transistor digital scanner with storage and parallel readout is described. It utilizes one of the plug-in decades. A simple design procedure for flip-flops is presented."

Response of a Low-Geometry Scintillation Counter to Fission and Other Products

Description: Abstract: The theoretical response of a low-geometry scintillation counter to any photon-emitting nuclide whose decay scheme is known is developed. It is used to compute the counting rate, as a function of time, of (1) individual and total fission products resulting from. 10^4 simultaneous slow-neutron fissions of U^235 and (2) several other nuclides for 10 initial atoms. The calculations extend from ~45 min to 301 days after fission.

Interval Between Pulses of Counter or Scaler

Description: This paper is based off of an operation of a recording tape scaler, which records pulses from a counter or scaler upon a tape as a function of time. With the recording tape scaler, the interval between pulses of counter or scaler is measured in this report.
