Abstract

The resolution of a summing Compton spectrometer ls accurately measured for several gamma ray energles. For the events detected, only one Compton scatterlng takes place in the first crystal. Thus for the part of the energy that is released ln the first crystal, the contrlbutlon to the line width arising otherwise from a varyng number of Compton electrons and non-proportlonal response of the scintillator is not present. Thls contrtbution ts evaluated by comparlng, for each energy, the resolutlon of the summing Compton spectrometer with the resolution expected if the total energy were shared by the two crystals in the same ratio, but multiple scatterlng were prcsent tn both of them. The results agree with theoretlcal expectattons. (auth)

THE EFFECT OF THE NON-PROPORTIONAL RESPONSE OF NaI(Tl) CRYSTALS TO ELECTRONS UPON THE RESOLUTION FOR $gamma$-RAYS

Journal Article Iredale, P - Nuclear Instr. & Methods

The resolution of Nal(Tl) scintillation spectrometers for gamma -rays is discussed, with particular reference to the intrinsic crystal resolution. Experiments indicate that differences in efficiency of light collection from various parts of the crystal and variations in photocathode efficiency have only a small effect upon the resolution. It is shown that because of the non- proportional response of Nal(Tl) to electrons, there is a contribution to the resolution arising out of the-variations in number and energy of electrons involved in the total absorption of a gamma -ray. Approximate calculations indicate that the magnitude of this effect is such that itmore »« less

EXPERIMENTAL DETERMINATION OF SUMMING DISTRIBUTIONS IN SCINTILLATION DETECTORS

Journal Article Vingiani, G B ; Monaro, S - Nuclear Inst. & Methods

A modlfication of the Hoogenboom summlng method ls used to determine the pulse helght dlstrlbution of summing pesks in NaI(Tl) crystals. The fast colncidence circult ts trlggered by time colncldent events ln two equal crystals and the sum of the two pulses dlsplayed on a multichannel analyzer. These distributlons are obtained for a number of standard sources with two colncident gamma rays and the general features of the shape of the pulse helght spectrum are dlscussed. Applications of thls method ln gamma scintillation spectroscopy are indicated, as for example the evaluatlon of the residual summing effect ln the analysis ofmore » gamma sclntlllatlon spectra.

NaI(Tl) SUMMING COMPTON SPECTROMETER

Journal Article Takekoshi, H - Rev. Sci. Instr.

A method of measuring gamma -ray energy by using two sodium iodide crystals is described. The sum of two pulses is to be taken: one from a crystal that scatters gamma rays by the Compton effect and the other from a second crystal that receives the scattered photon. In comparison with the scintillation Compton spectrometer hitherto developed, this method is good both in efficiency and in resolution. (auth)

GAMMA-RAY RESOLUTION OF LARGER NaI(Tl) SCINTILLATORS

Journal Article Hickok, R L ; Draper, J E - Rev. Sci. Instr.

The various factors affecting the gamma-ray energy resolution of NaI(Tl) scintillation spectrometers have been investigated experimentally with commercially packaged 2.5- and 5-in. diam scintillators and routinely available 3- and 5-in. photomultipliers. The resolution contains contributions from the scintillator light yield, photocathode efficiency, intrinsic resolution due to the material NaI(Tl) and two terms involving the effects of various spatial inhomogeneities in the packaged scintillator and photomultiplier. Insofar as possible these contributions are experimentally separated. The poorer resolution of the 5-in. systems is in about equal measure caused by their smaller light yield, their larger spatial inhomogeneities and the lower efficiency ofmore »« less

Theoretical studies of image artifacts and counting losses for different photon fluence rates and pulse-height distributions in single-crystal NaI(Tl) scintillation cameras

Journal Article Strand, S E ; Lamm, I L - J. Nucl. Med.; (United States)

Using computer simulations, we have developed a theoretical model to explain the correlation between counting losses and image artifacts in single-crystal NaI(Tl) scintillation cameras. The theory, valid for scintillation cameras of the Anger type, is based on the physical properties of the NaI(Tl) crystal. Based on a statistical model using random numbers, pulse trains of the light pulses from scintillations were simulated. Pulse-height distributions for different event rates were calculated, with various Compton distributions. Immages of point sources and line sources were generated. Counting losses and image artifacts were dependent on the shape of the pulse-height distribution. The calculated countingmore »« less
