    A thorough investigation of the response of NaI(Tl) in the region below 50 kev was made using a continuous distribution of X-rays from a tungsten target as well as monoenergetic gamma rays from radioactive sources. The results of this investigation agree well with those of Engelkemeir.1 The investigation also showed that below 20 kev NaI(Tl) is sensitive to surface treatment. Above 20 kev the resp...

    This paper reports a series of experiments on the pulse-height response of CsI(Tl) crystals to monoenergetic gammas, protons, and alphas, in an effort to examine some predictions of a previously proposed model of the scintillation process. Analysis of the data to date indicates the following: The pulse height per unit energy for gammas is an energy-dependent function which reaches a maximum near 2... View full abstract»

    Experimental results from Yale indicate that the scintillation efficiency of inorganic crystals to heavy particles is not a function of dE/dx alone but is instead composed of a series of discrete functions, one for each incident particle. This paper presents an analysis of these experimental results with attention to the effect of delta rays produced by the primaxy particle. In this treatment the ... View full abstract»

    Sodium Iodide activated with thallium was used as the detector in a scititillation counter. The scintillating crystals were stressed with the intention of introducing oislocations and observing whether or not there was any measurable effect on the scintillation enercy resolution intrinsic to the crystal.

    The relative pulse height for all alkali iodide crystals, with and without activation, in response to alpha particles and protons was measured as a function of the incident particles energy at both liquid nitrogen and room temperatures. In all cases the response curve is linear for protons of an energy range from 1 to 10 Mev, linear for alpha particles of high energies, but clearly nonlinear gener... View full abstract»

    The time-response of high-gain transmission-type dynodes using KC1 in the form of a low density layer is investigated. Both the results using light-pulses and charged particles directly incident on these dynodes indicate no detectable time lag within the limits of the experimental method (< 0.5 ?? 10-9 sec).

    Thin films of semiconducting materials with secondary electron emission ratios greater than one have been used for some years in the Bendix crossed electric and magnetic field electron multiplier for ion detection. In these devices the electric field to accelerate the electrons is established by the potential gradient created by external current flowing through the resistive strip. A low backgroun...

    The tubes to be described are of the transmission secondary emission type. Electrons from a tri-alkali photo-cathode are accelerated and focused on to a series of dynodes where multiplication takes place by transmitted secondary emission. The electrons from the final dynode are then focused on to the output phosphor. View full abstract»

    Our measurements of the amplitude distribution of photomultiplier anode pulses due to the emission of single-electrons from the cathode consistently show a peak. It is significant that the peak position agrees with that of a calculated distribution based on a Poisson distribution of secondary electrons at each dynode. The integral distribution, obtained by counting single-electron pulses, tends to... View full abstract»
