We present the final report from a series of precision measurements muon anomalous magnetic moment, ${a}_{\ensuremath{\mu}}=(g\ensuremath{-}2)/2$. The details experimental method, apparatus, data taking, and analysis are summarized. Data obtained at Brookhaven National Laboratory, using nearly equal samples positive negative muons, were used to deduce ${a}_{\ensuremath{\mu}}(\mathrm{\text{Expt}})=11659208.0(5.4)(3.3)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}10}$, where...
A higher precision measurement of the anomalous g value, a(mu)=(g-2)/2, for positive muon has been made at Brookhaven Alternating Gradient Synchrotron, based on data collected in year 2000. The result a(mu(+))=11 659 204(7)(5)x10(-10) (0.7 ppm) is good agreement with previous measurements and an error about one-half that combined data. present world average experimental value a(mu)(expt)=11 203(8)x10(-10) ppm).
About 3 × 105 extensive air-shower events were recorded at Auckland (altitude 40m, latitude 37° S.) with counter trays the corners of a 4 m triangle, each sensitive area 2360 cm2, in period February 1951 to 1952. The results show solar diurnal amplitude (1.45 ± 0.25)% maximum (2.7 0.6) hours local time and sidereal (1.10 0.26)% (19.8 0.9) (standard errors). By introducing concept antisidereal (there are 364.2 days per year) an allowance is made for seasonal modulation variation. When this...
The thermodynamic theory of the condensation supersaturated vapours at cloud limit is given in detail. A calculation rate drop formation water vapour a typical expansion chamber gives reasonable agreement with experiment. predictions as to dependence on temperature, and nature condensing vapour, appear be correct, although experimental data here are incomplete.
Laboratory measurements of the performance Anaconda are presented, a wave energy converter comprising submerged water-filled distensible tube aligned with incident waves. Experiments were carried out at scale around 1:25 250 mm diameter and 7 m long tube, constructed rubber fabric, terminating in linear power take-off adjustable impedance. The paper presents some basic theory that leads to predictions distensibility bulge speed pressurized compound fabric including effects inelastic sectors...
A long tube with elastic walls containing water is immersed in the sea aligned direction of wave travel. The waves generate bulges that propagate at a speed determined by distensibility tube. If bulge close to phase velocity waves, there resonant transfer energy from bulge. At end tube, useful can be extracted. This paper sets out theory tubes sea, and describes some experiments on model scale practical problems. potential full-scale device assessed.
Clouds are produced in an expansion chamber filled with air and water vapour by irradiating ultra-violet light through a quartz window, expanding shortly afterwards. It is shown that the condensation does not occur upon charged particles, but on certain electrically neutral nuclei, yet identified. By varying wave-length of it initiated atomic oxygen, liberated action radiation oxygen molecules. Similar effects when intense beam deuterons passed into chamber.
The redshifts and luminosities of Type 1A supernovae are conventionally fitted with the current paradigm, which holds that galaxies locally stationary in an expanding metric. fit fails unless expansion is accelerating; driven perhaps by "dark energy". Is recession slowed down gravity or speeded up some repulsive force? To shed light on this question apparent magnitudes type re-analysed a cartesian frame reference omitting gravitational effects. redshift ascribed to relativistic Doppler...
Extensive air showers corresponding to primary cosmic rays ranging from 1014 3 × 1015 eV were recorded at Auckland for the year 1955. The results do not confirm large sidereal diurnal effect reported previously.
A new derivation is given of an equation, relating the capture width a wave power converter to polar diagram waves generated by device. The pattern in lee device calculated detail.
A circuit for pulse height discrimination in fast counting systems is described. Input pulses whose amplitude exceeds the threshold bias, adjustable from 1 to 21 volts, give rise a positive output of standard (6 volts), but length determined by input signal. Dead time order 20 mμsec and peaks 40 apart are handled independently.
This instrument is designed for measuring the amplitude of voltage pulses with particular application in nuclear counting. An output pulse obtained only when input has an lying between two preset limits; lower limit being variable from 5 to 50 V, and interval limits 0.5, 1, 2, 3, or 7.5 selected by a switch. The can also be used as simple discriminator. A feature this that without readjustment it deal wide variety pulses, ranging 0.2 μsec over 1000 length. In all cases dead time few tenths...
