Physics experiments at the SLAC National Accelerator Laboratory (SLAC) usually require high accuracy positioning, e. g. 100 μm over a distance of 150 m or 25 μm in a 10 x 10 x 3 meter volume. Laser tracker measurement systems have become one of the most important tools for achieving these accuracies when mapping components. The accuracy of these measurements is related to the manufacturing tole...

On-line monitoring of beam quality for high brightness beams is only possible using non-invasive instruments. For matching measurements, very few such instruments are available. One candidate is a quadrupole pickup. Therefore, a new type of quadrupole pickup has been developed for the 26 GeV Proton Synchrotron (PS) at CERN, and a measurement system consisting of two such pickups is now installe...

We study the spreading of viscous nonvolatile liquids on smooth horizontal substrates using a phase-modulated interference microscope with sufficient dynamic range to enable the simultaneous measurement of both the inner ("microscopic") length scale and the outer ("macroscopic") flow scale in addition to the intermediate matching region. The resulting measurements of both the apparent contact a...

A measurement of the horizontal coherence function of 7.9 keV radiation from an undulator beam line at the Advanced Photon Source is reported. X-ray diffraction from a phase-shifting mask was used, and the coherence function was measured as a function of the width of beam-conditioning slits in the beam line. The coherence distribution is found to be best described by a Lorentzian function.

This work refers to the reduction of the atmospheric horizontal mean free path data in the northern Pierre Auger Observatory site, in Millard County (Utah). Basically, the measurement consists in a series of photometric data obtained by CCD cameras that record the signal of two light bulbs placed near the ground during the night. The data acquisition was automated, and covered an almost full ye...

We propose to apply Ramsey’s method of separated oscillating fields to the spectroscopy of the quantum states in the gravity potential above a horizontal mirror. This method allows a precise measurement of quantum mechanical phaseshifts of a Schrödinger wave packet bouncing off a hard surface in the gravitational field of the Earth. Measurements with ultracold neutrons will offer a sensitivity ...

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Measurement of solar radiance demands expensive devices to be used. Alternatively, estimator models are used instead. In this paper, a new method based on the empirical equations is introduced to estimate the monthly average daily global solar radiation on a horizontal surface. The proposed method uses Intelligent Water ...

abstract background and aim: cone beam computed tomography (cbct) produces high-quality data in periodontal diagnosis and treatment planning. the aim of this study was to compare the accuracy of cbct with intraoral digital and conventional radiography in the measurement of periodontal bone defects.  methods and materials: in this diagnostic research, two hundred and eighteen artificial osseous ...

industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...
