    Cerenkov light in the central region of a water-moderated reactor has been measured as a function of reactor power. Simple photovoltaic light detectors were used with a recording microammeter. The electrical current responded to a power increment increase with an initial rise proportional to the reactor power. This was followed by an additional increase in current of from 4 to 5% with a time const... View full abstract»

    Circuits are shown and design criteria given for a current-regulated power supply which is typical of 19 supplies of four types built for the Oak Ridge Isochronous Cyclotron. These supplies range from 6.25 to 34 kw with current ratings from 250 to 1200 amp. Current regulation and ripple of 1 part in 104 are obtained by separate ac and dc feedback circuits driving a bank of parallel power transisto... View full abstract»

    Due to a very unusual-effect that occurred when certain transistors were operated at low current levels, a direct coupled, transistorized, current amplifier has been developed with sensitivity extending below the millimicroampere region of input currents. This amplifier was necessary for the measurement of certain characteristics of the experimental controlled fusion machine, DCX (Direct Current E... View full abstract»

    The ¿-ray fluxes in space which arise from nuclear and plasma interactions are expected to be of the order of 10-1 to 10-2 photons/cm2.sec. A considerable ¿-ray backgrond is produced from the interactions of cosmic-ray nucleons. A detection ystem is described which will allow the measurment of considerably weaker primary fluxes than previous experiments. The apparatus is to be placed on a low-al... View full abstract»

    The three-fold coincidence telescope is a compact, flexible instrument providing cosmic-ray measurements related to the charged-particle flux at a well-defined low-energy cutoff. The output to the space-crafts data-handling system may be in either analog or digital form. The experimental results to date have provided useful information of the space environment at distances from 200 miles to some 2... View full abstract»

  • Instrumentation for Use with BEV Accelerators

    Publication Year: 1961, Page(s):34 - 39
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (869 KB)

    The object of the instrumentation is to observe the interaction of high energy protons with various nuclei and to study the characteristics of the short-lived particles which are produced. The tracks of charged particles can be directly observed in photographic film, in cloud and bubble chambers and in spark chambers. Alternatively, a number of radiation detectors may be arranged to give a signal ... View full abstract»

    Publication Year: 1961, Page(s):40 - 50
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3327 KB)

    The paper describes electronic instruments and techniques which have been developed and used in support of the U.K. plasma physics research programme. These generally fall under the headings of machine design, machine control and instrumentation, and plasma diognostics. To date, most work has been in the latter category which involves a wide variety of measurements ranging from the low frequency e... View full abstract»

  • Dangers in Safety Systems

    Publication Year: 1961, Page(s):51 - 55
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1445 KB)

    Reactor safety systems have failed in such a way as to destroy the reactor which they were intended to protect. Safety rods, when released, can, through malfunction, increase rather than decrease reactivity. The electronic and sensing portions of the safety system are usually arranged so that random failures may on rare occasions result in a slight impairment of protection. The total loss of prote...

    Most of the properties of plasmas are difficult to determine. This is especially true for high temperature, dense, transient plasmas such as encountered in controlled fusion research. If high temperatures and long plasma confinement times are to be achieved the measuring instruments must not perturb the plasma. Since each transient event has its own personality and cannot be expected to be exactly... View full abstract»

    In the Multi-Stage Compression Experiment (Toy Top III) we wish to determine the energy and spatial distribution of the plasma components - ions and electrons - from the time of their initial injection into the machine through the heating and containment cycle. An ion analyzer, consisting of a magnetic momentum analyzer followed by an electrostatic analyzer, has been valuable in finding the energy... View full abstract»

    The techniques which have been used to measure properties of the plasma produced by high energy injection into a magnetic mirror have been described. The results obtained have been illustrative of gas breakup; however, the same methods have been used unaltered to measure the energy dispersion and stability with a magnetically confined high density arc as the breakup mechanism. The application of t... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1089 KB)

    In the recovery of uranium from spent nuclear fuel elements, a waste stream from one solvent extraction cycle may be recycled as scrub solution to the prior cycle of the process. The waste solution may, as a result of this recycle, enter large columns where a critical accumulation of U-235 is prevented by concentration rather than size limitations. A continuous monitor was required to detect chang... View full abstract»

    A very accurate alternating current limit detector is presented. Its design philosophy, specially suited for multi-channel applications is based on dynamic monitoring of both limits through the same channel. Completely solid-state, this limit detector exhibits an accuracy of ± 0.1 % over a temperature range from 0 to 45° C. The design is inherently failsafe; and reliability evaluations were perf...

    A fixed filter paper alpha air monitor has been developed which will sound an alarm within 15 minutes for a uranium dust in air concentration of 6 picocuries per cubic foot. The cause and effect of background variations are discussed. Typical natural background data accumulated over a six months period are included. A prototype instrument has been built and operated satisfactorily. The final model... View full abstract»

    IV. Summary The purpose of this paper is to demonstrate for certain conditions that transmutation of elements can result in a temperature measurement error that is reasonably predictable. Methods are developed for estimating the errors for the purpose of: (1) Engineering judgment in selecting temperature measuring elements for application; (2) Obtaining the order of magnitude for expected error in...
