Study of a liquid scintillation counter
Il Nuovo Cimento, 1954This paper deals with a liquid scintillation counter of small thickness (1 cm) and of circular cross-section (10 cm in diameter). The measurements have shown that its efficiency in revealing relativistic particles is practically 100%, and that its real diameter corresponds to the geometric one. The measurements permit the conclusion that the collection

Liquid Scintillation Counter (LSC) at Yemilab
Physics and High Technology, 2023The construction of the Korea’s 1st deep underground laboratory, called Yemilab, dedicated to science was completed in September, 2022 in Handuk iron mine, Jeongseon-gun. The Yemilab construction includes excavation of a large cylindrical cavern (Diameter: 20 m, Height: 20 m) to host a future neutrino detector to be filled with 2,260 ton liquid ...

Afterpulses in liquid scintillation counters
Nuclear Instruments and Methods, 1973The methods available for the detection of afterpulses are described and their relative advantages are compared. A brief review is given of some of the more recent experimental work on afterpulses in photomultipliers and liquid scintillation systems and the areas where it may be worthwhile carrying out further measurements are discussed.

Liquid scintillation counter stability
Nuclear Instruments and Methods in Physics Research, 1982Abstract Measurement of the count rate stability of 22 liquid scintillation counters are presented using standard gamma and neutron sources, the latter with PSD applied against gammas. Each detector system is nominally identical and no explicit method of gain stabilisation is incorporated.

Computerized tritium measurements with a liquid scintillation counter
Computers & Chemistry, 1988Abstract Computer support was added for tritium measurements with a liquid scintillation counter. A single chip microprocessor performs long-term data aquisition instead of a Teletype and stores the results in a battery protected semi-conductor memory.

Performance of large liquid scintillation counters
Nuclear Instruments and Methods, 1963In a systematic study of the performance of large scintillators, a container in the form of a rectangular parallelepiped with the larger surface st run. Concent 2 m/sup 2/ and with a thickness for the liquid of 14 cm was used. The counter was placed between two telescope counters of 10 x 10 cm/sup 2/ in a beam of relativistic mesons. The counter pulses

Improved Noble Liquid Scintillation Counter
Review of Scientific Instruments, 1963The counter comprises a Dewar vessel whose helium reservoir terminates in a sapphire window, and a photomultiplier operating in vacuum below the window. Diphenylstilbene is used as a wavelength shifter. Some resolution and pulse height measurements on the counter are given.

Applications of Liquid Scintillation Counters
IRE Transactions on Nuclear Science, 1958The liquid scintillator, in just a few years of development, has shown itself to be an extremely versatile chemical system for radiation detection. Its evolution has been characterized by penetration into almost every phase of experimental science. A survey of the most notable applications of liquid scintillation counting is presented.

Direct measurement of 14CO2 in a liquid scintillation counter
The International Journal of Applied Radiation and Isotopes, 1968Abstract Samples of CO2 are dissolved in a liquid scintillator solution for the measurement of 14C activity with counting efficiencies of greather than 90% above an appropriate low-energy bias. With an integral counting technique, the counting efficiency of (100 ± 2)% was obtained. As much as 5 ml (STP) of CO2 per ml of scintillator solution produced

Small animal and infant liquid scintillation counter
The International Journal of Applied Radiation and Isotopes, 1969Abstract Performance and calibration of a small animal or infant liquid scintillation counter is described. With this instrument it is possible to measure the total amount of potassium in an animal or an infant which contains 10–12 g of potassium with an accuracy of 4% at 1 standard deviation or at 8% for 2 standard deviations for a counting time of ...
