    Systems with naxiwum pulse flow capacity are discussed. It is shown that the upper limit of the permissible counting rates is set by pile up induced phenomriena, which are analyzed here. The best pulse stretching mode miinimizing pile up is peak value extraction. The basic statistical properties of such a device are investigated. These principles are applied to the design of an electronic system w... View full abstract»

    A pulse - measuring technique, in which pulses are measured on the basis of area rather than amplitude, is employed in the design of a pulse window amplifier. This pulse-area-integration technique is used primarily to improve linearity, reduce resolution degradation resulting from risetime jitter, and simplify amplifier drive requirements.

    The performance of high resolution pulse amplitude spectrometers is often seriously degraded at high counting rates due to baseline problems of various kinds. A variation on the Robinson double-diode dc restorer is presented which makes it possible to obtain high resolution with Li-drifted Ge spectrometers at counting rates greater than 50,000 per second.

    It is well-known that while the use of single clipping yields optimum energy resolution in nuclear pulse spectrometry it suffers from the drawback of producing rate-dependent baseline shifts. On the other hand the use of double clipping removes the baseline shift but degrades the signal-to-noise ratio. A scheme has been devised which circumvents some of these problems by producing a signal proport... View full abstract»

    Channel multiplier instruments have been developed and used to measure the low-energy electron and proton auroral fluxes from a polar-orbiting satellite. Seven channel multipliers preceded by individual 90° magnetic analyzers were used to measure the differential electron energy spectrum. The central energies of the analyzers were 1.1, 2.1, 5.3, 14, 31, and 76 keV; the seventh channel was designe... View full abstract»

    This paper describes the electronic instrumentation of a stilbene scintillation detector which is used as a neutron spectrometer. In this application, the spectrum of scintillations caused by protons from (n,p) reactions must be measured and recorded for further analysis. The proton scintillations are separated from the electron scintillations by a double delay-line, pulse-shape discriminator. The... View full abstract»

    A new and useful theory was developed to characterize switching properties of the tunnel diode. Expressions for time delay and time variance for small signals in the presence of amplitude noise were developed for the tunnel diode in the discriminator mode. The expression for time variance is used to determine the parameters of the tunnel diode, and the tunnel diode bias condition to obtain the opt... View full abstract»

    The results of an investigation of the delay time variation of a tunnel diode (TD) threshold sensing discriminator are presented. These variations are a function of the square root of the input signal risetime and are accountable in terms of a charge sensitivity of the tunnel diode. A distinction is made between the charge sensitivity due to continuously rising signals and that due to short low en... View full abstract»

    An investigation has been made of a new type of insulated gate field effect transistor (IGFET), in which the gate lead is brought through the header in a guarded configuration. Measurements of gate leakage current with the drain connected to the source on this guarded IGFET show that its gate leakage current is less than 1/10 that of the conventional device, demonstrating that most of the leakage ...

    A new all-solid state direct-current integrator integrates currents as low as 10-11 ampere with an accuracy of 1%. The operating principle is similar to that of more conventional current integrators in that the voltage across a storage capacitor in the input circuit is monitored by an electrometer type operational amplifier, the output of which triggers a discriminator at a given voltage level.

    A new technique (Double Sampling) of photomultiplier pulse processing is studied in order to improve the time resolution. Two time references, t1, and t2, are obtained from two different processing systems, into which the fast pulse of the photomultiplier is fed. If the condition: (t1 - t2) -¿t < (t1 -t2) < (t1 - t2) + ¿t is satisfied, the pulse is accepted for the time analysis. ¿t is a predet... View full abstract»

    Many radiation counter applications require the rapid response speed of a digital ratemeterl & 2, but if large changes in count rate are encountered, a conventional digital ratemeter must be set for a short counting period, producing an excessive number of individual measurements. An instrument is described which avoids this difficulty by automatically adjusting its time base as the count rate cha... View full abstract»
