Organic Scintillators

Studies of the relative Light output and optical transmission of organic composite scintillators with different grain sizes were performed. The research results showed that for samples with grains 0.06…0.3 mm in size, in contrast to the samples with larger grains, the relative light output and optical transmission are lower.

Relative Light Output

The relative light output of liquid scintillator based on p-xylene (PX) was measured in this paper. The setup for testing on light output was clearly displayed. The results showed that the light yield increased as the addition of the second solute p-bis (o-methylatyryl)- benzene (bis-MSB). Bis-MSB moves the maxmun of fluorescence emission spectra of liquid scintillator from 365nm to 425nm, which is the most sensitive region for the PMT, so the possibility of self-absorption and the loss of light output could be reduced to some extent.

Relative Light Output

Transparent ceramic scintillators of La2Hf2O7:Ti4+ were developed by a novel combustion synthesis method. The optical transmittance for a 1.0-mm-thick specimen is about 60% of the incident light, and the x-ray stopping power is also quiet high. The broad emission band centered at 475 nm originates from the oxide-Ti4+ charge-transfer transitions, which renders fast decay time on the order of 10 μs. The highest relative light output has reached about 1.5 times that of Bi4Ge3O12 (BGO) single crystal when excited by 120 kV x-rays.

Counter Telescope

A dE/dx by E counter telescope consisting of two ¼-in.-thick plastic scintillators as the dE/dx elements and a 5-in.-deep NaI(Tl) crystal as the E element is described. The geometrical factor of the system is 6 cm2 sr and is energy independent for stopping particles. The calibration of the detector and its response to sea-level muons and the low-energy nuclei of cosmic radiation are presented. The expected mass resolution is compared to that observed, and they are found to be in excellent agreement. Protons, deuterons, 3He, 4He, and heavier nuclei are all resolved over the energy range corresponding to the crystal thickness. Information on the nonlinear behavior of the light output from the plastic scintillator NE102 as a function of ionization loss is presented.

Abstract Objectives Purpose of this research was to find the best blue-emitting fluorescent substance for plastic scintillator used for gamma radiation dosimetry. Scintillator should convert gamma radiation into blue light with high efficiency. Methods Plastic scintillators with fixed concentration of various fluorescent additives, called wavelength shifters, absorbing ultraviolet light and emitting blue light were manufactured by radical bulk polymerization of styrene. Light output were measured and compared to the light output of commercial plastic scintillator. Results Performed measurements of charge Compton spectra confirmed usefulness of majority of researched substances as wavelength shifters in plastic scintillators with emission maximum at blue range of visible light. Conclusions Plastic scintillation dosimeter may be constructed from manufactured polystyrene-based scintillators. Performance of synthesized scintillators is close to commercial polystyrene scintillators.
