Several readout techniques for undoped CsI have been studied which utilize the fast scintillation component for speed, and the high photon yield for good energy resolution. Quantum yields have been measured for samples up to 30 cm in length using photomultiplier tubes, wavelength shifters, and silicon photodiodes. A study has also been made of the scintillation properties of undoped CsI. It is found that the light output and decay time of the 310 nm fast component increases and the emission spectrum shifts to longer wavelengths at lower temperatures. The effects on the optical transmission and scintillation light output due to radiation damage from {sup 60}Co gamma rays has been measured for doses up to {approximately}10{sup 6} rad. It is found that the radiation resistance of undoped CsI is substantially higher than has been reported for thallium doped CsI. 16 refs., 11 figs., 3 tabs.
