Physics Today, 1949
During the past year, the scintillation counter has received widespread acceptance as a fundamental tool of nuclear research. It offers three advantages over previous counters: The light output is proportional to the amount of energy lost by the particle, thereby supplementing the beta proportional counter in the high energy region; it detects gamma ...

American Journal of Physics, 1952
A review of the present status of liquid scintillators is given. The theory explaining the properties of the counters is discussed. Preparation of counters is described and counter characteristics such as emission spectra, response to various nuclear radiations, counting efficiencies, and emission intensities from various scintillating solutions are ...

Filament Scintillation Counter
Review of Scientific Instruments, 1957As a part of a program to develop a solid scintillation chamber, filaments of plastic scintillator material were prepared and formed into a scintillation counter. The filaments can be prepated in lengths of many feet. Care must be taken to avoid surface crazing. The diameter was chosen between 0.5 and l.0 mm in view of the proposed application.

Nuclear scintillation counters
Journal of the British Institution of Radio Engineers, 1951Nuclear radiations impinging on a phosphor produce short flashes of fluorescence, or scintillations, which may be used to detect and measure the radiations. Major advances have recently been made in this technique, through the introduction of high-gain photo-multipliers to detect the scintillations.

Neutron Scintillation Counters
IRE Transactions on Nuclear Science, 1956The various types of neutron scintillation detectors are examined with respect to efficiency, background sensitivity, pulse height and time response. Actual performance of certain counters under different source conditions are considered. These are given in Fig. 1, and include a few imaginary (3) cases.

Abstract All experiments based on the use of radionuclides depend at some time or another on the detection of radioactivity. Therefore, the quality and reliability of the experimental results and subsequent interpretation depends on the accuracy and dependability of the detection system.

Scintillation counter stability
Nuclear Instruments and Methods, 1980Abstract In view of the lack of available data on the stability over a period of days of a typical scintillation counter system with “standard” electronics, a brief report is presented on the performance of twelve scintillation counter systems over a period of six days.

Directional Scintillation Counter
Review of Scientific Instruments, 1958A collimated scintillation counter was developed which employs bundles of pyrex capillaries filled with a liquid phosphor (xylene with terphenyl and POPOP). Two such counters were constructed and tested; one with 2.8-Mev neutrons, the other with 14-Mev neutrons. Directional ratios of R = 60 and axial efficiencies E = 0.1% were obtained. (D.E.B.)

Publisher Summary This chapter discusses the performance of scintillation counter. The essential components of a scintillation counter are a phosphor crystal, a secondary emission multiplier, and some form of presentation device; for example, a pulse height selector and a pulse counter.
