Calibration and Neutral - Current Detectors II
نویسنده
چکیده
We revise and update SNO-STR-92-094 to identify and quantify sources of systematic uncertainty in determining the efficiency for detecting neutrons resulting from the neutralcurrent neutrino disintegration of deuterium. We conclude that aUowing for two standardized neutron sources (one strong, one weak) that can be moved vertically within the cylinder defined by projecting the vessel neck downward through the vessel permits adequate calibration. Somewhat better results can be obtained with sources that can be moved in one or two vertical planes bisecting the vessel, but the precision is mainly limited by factors other than calibration.

Simulation Calibration of an Extensive Air Shower array, by a logged data set of its small prototype
Alborz observatory is an EAS array in the heights of Alborez mountain chain near Tehran. For the development of the array, more number of detectors is inevitable. The managing the financial resources and achieving the highest efficiency of the array is important for the project. Therefore, Water Cherenkov Detectors has been used for 9 months in the same way as the previous experiment with Scint...
متن کاملCalibration procedures for charge-coupled device x-ray detectors
Calibration procedures are described for use with electronic x-ray detectors, with an emphasis on detectors based on fiber-optically coupled charge-coupled devices. Methods are detailed for removing spurious events, pixel pedestals, dark-current, spatial distortion, and intensity response variations for both small-angle and wide-angle applications. The accuracy of the calibration procedures is ...

One of the most important requirements for industrial pipelines is the leakage detection. In this paper, detection of leak and determination of its amount using radioactive tracer injection method has been simulated by Monte Carlo MCNP code. The detector array included two NaI (Tl) detectors which were located before and after the considered position, measure emitted gamma from radioactive trac...

This paper proposes a new approach for calibration of dead reckoning process. Using the well-known UMBmark (University of Michigan Benchmark) is not sufficient for a desirable calibration of dead reckoning. Besides, existing calibration methods usually require explicit measurement of actual motion of the robot. Some recent methods use the smart encoder trailer or long range finder sensors such ...
