A plastic scintillation counter prototype
Applied Radiation and Isotopes, 2015A new prototype device for beta-ray measurement, a plastic scintillation counter, was assembled as an alternative device to liquid scintillation counters. This device uses plastic scintillation sheets (PS sheets) as a sample applicator without the use of a liquid scintillator.

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.

Review of Scientific Instruments, 1957
A systematic investigation of the optimum conditions for the design and operation of a gas scintillation counter has been made. The gases studied were xenon, krypton, argon, helium, and various gas mixtures. Both a 6292 and a quartz window K1306 phototube were used with and without quaterphenyl as a wavelength shifter.

Stabilized Scintillation Counter
Review of Scientific Instruments, 1961A scintillation counter spectrometer is described that is stabilized against temperature drifts, changes with time, and variations between photomultiplier tubes. A standard light pulse is used, whose amplitude is constant and larger than any amplitude in the spectrum being studied. These "pilot" pulses are amplified and fed into a feedback circult that

Characteristics of Scintillation Counters [PDF]
Proceedings of the Physical Society. Section B, 1952 Experimental studies have been made of the distribution in size of output pulses from a scintillation counter detecting monoenergetic alpha-particles. Separate investigations have been made of contributions to the pulse size spread by the photomultiplier and by the scintillating crystal It is shown that the main effect is due to statistical ...

Thin-Crystal Scintillation Counter
Radiology, 1959The preoperative detection and identification of many types of lesions such as mediastinal tumors (1) have depended upon the use of the Geiger-Muller counter. The conventional scintillation counter has been generally inapplicable due to its size and weight.

Timing with Scintillation Counters
IEEE Transactions on Nuclear Science, 1981A minimum time-resolution expression is considered for leading-edge timing in which the rise time T1 of SER and its decay time T2 are inserted. Correlation with the parameters involved in other theories indicates the scintillator contribution to T1, which is shown to be the rms time jitter of the photomultiplier at small thickness of scintillator ...

Analytical Chemistry, 2000
In miniaturized separation techniques, such as capillary electrophoresis (CE) or capillary liquid chromatography (LC), conventional on-line radioactivity detection of labeled compounds is restricted, because of insufficient sensitivity.
