FIG. 1.

Comparison of the calculated cerium emission decay curves (circles) in : 0.2% at four temperatures with the fitted curves (lines) of Bizarri and Dorenbos (Ref. 32).

Comparison of the calculated (closed symbols) contributions of STE and emissions to the total light output of : 0.2% as a function of temperature with the data of Bizarri and Dorenbos (solid symbols) (Ref. 33).

FIG. 3.

Comparison of the calculated (closed symbols) and observed (solid symbols) (Ref. 32) light output of : 0.2% as a function of temperature.

FIG. 4.

Particle-particle distance distribution functions obtained for a 20 keV incident photon in CsI and . Distributions were scaled so that integration over the entire distance range yields one.

FIG. 5.

Light output of pure CsI and : 0.2% , expressed in fraction of electron-hole pairs emitted, as a function of annihilation probability, . Results were obtained with a 2 keV-incident photon at 100 and 300 K for pure CsI and : 0.2% , respectively.

FIG. 6.

Relative light output of pure CsI as a function of incident energy for three annihilation probabilities at 100 K. All three curves were normalized to the light output at 400 keV.

Relative light output of pure CsI as a function of incident energy for three temperatures as calculated with two annihilation probabilities (model ; model ). All curves were normalized to the light output at 400 keV.

FIG. 8.

Comparison of the relative light yield of pure CsI obtained with model 2 at 100 K with experimental data from nominally pure CsI samples (a) (Ref. 12) and Tl-doped CsI samples [(b) (Ref. 46); (c) (Ref. 45)]. Experimental data sets have been normalized to the value of the relative light output of pure CsI at 22 keV as obtained by Moszyński et al. (Ref. 12) with sample B.

Comparison of relative light yield obtained with model 2 at 300 K with experimental data [(a) (Ref. 15); (b) (Ref. 16); (c) (Ref. 17); (d) (Ref. 18); and (e) (Ref. 19].
