Cargo Containers

AbstractExperimental results from a dataset collected with a full-scale muon tomograph for the inspection of cargo containers were studied in a single scattering scenario with a multiparametric analysis based on the method of the Point Of Closest Approach (Poca). To search for high-Z materials, a 4 $$\hbox {dm}^3$$ dm 3 Pb block was positioned inside the volume to be inspected, in order to quantitatively investigate the appearance of the Poca signal. Signal-to-noise ratio and significance of the Poca signal were investigated by means of mono-dimensional spectra of the Poca components, for different values of the scattering angle between the incoming and outgoing muon tracks and with different angle-dependent weights. A systematic scan of two-dimensional maps was also carried out, as a strategy to search for possible enhancements to the Poca signal. A comparison was also done between the results obtained from the two half-volumes, one containing the Pb block and one left empty, to take into account the response of the detector and some aspects of the Poca strategy.

Noise Ratio

The two-dimensional distributions of the potential, current, and surface charge for a magnetic-field-sensitive N-channel MOSFET have been computed numerically. The MOSFET is operated in the linear region and is based on a triple-drain configuration. The sensitivity as well as the signal-to-noise ratio is studied for a variety of channel geometries, and an optimal device geometry is presented.

Noise Ratio

This chapter introduces the ideas used in gravitational-wave data analysis, starting from matched filtering and building up to Bayesian inference analysis. Key concepts like the signal-to-noise ratio are defined and their use in actual searches is demonstrated by examples.
