Publications

Note, there are two types of publications here, fully peer-reviewed journal publications and conference papers. Nevertheless, most of the presented conference papers have been critically reviewed as well. As a matter of fact, my dissemination channels are targeting a specific audience from different industrial sectors: steel production and nuclear detection. Industrial algorithms used within such competing market environments are often a critical piece of intellectual property and consequently not every detail can be published.

A cognitive filter to automatically determine scintillation detector materials and to control their spectroscopic resolution during temperature changes

Marcus J. Neuer and Elmar Jacobs, IEEE Transactions on Nuclear Science, Volume 61, Issue 3, June 2014
Part I of a paper series on cognitive filtering

Abstract: The shape of the nuclear signal from scintillators contains information about the detection material from which it originated and its current temperature. A digital filter for this type of signals is presented that automatically extracts both of these pieces of information from the shape of the signals and controls the temperature dependency of the resolution by continuous adaption to this shape. Hereby, nuclear signals are a-priori modelled by an all-pole filter. The concept combines a deconvolution approach based on this model with a least-mean-squares iteration. Beneath the iteration, there is a continuous assessment of the signal shape where the mean-squared distance between the assumed shape and measured shape acts as control parameter for the resolution. From the information stored inside the dynamic filter parameters, the material characteristics are retrieved to identify the detector material. An

implementation into a multi-channel-analyser is shown and the technique is verified under real-world environmental conditions.

Spectral identification of a 90Sr source in the presence of masking nuclides using Maximum-Likelihood deconvolution

Marcus J. Neuer, Nuclear Instruments and Methods in Physics Research A, Volume 728, p. 73-80, 2013

 

A technique for the spectral identification of strontium-90 is shown, utilising a Maximum-Likelihood deconvolution. Different deconvolution approaches are discussed and summarised. Based on the intensity distribution of the beta emission and Geant4 simulations, a combined response matrix is derived, tailored to the β- detection process in sodium iodide detectors. It includes scattering effects and attenuation by applying a base material decomposition extracted from Geant4 simulations with a CAD model for a realistic detector system. Inversion results of measurements show the agreement between deconvolution and reconstruction. A detailed investigation with additional masking sources like 40K, 226Ra and 131I shows that a contamination of strontium can be found in the presence of these nuisance sources. Identification algorithms for strontium are presented based on the derived technique. For the implementation of blind identification, an exemplary masking ratio is calculated.

Surveillance of nuclear threats using multiple, autonomous detection units

Marcus J. Neuer, Kai Ruhnau, Arne Ruhnau, Ralf Lentering, Guntram Pausch, Frank Platte and Jürgen Stein, Nuclear Science Symposium Conference Record (NSS/MIC), Dresden, 2008

 

Abstract: A detection systems is presented that involves multiple autonomous detectors, which are merged to a net like structure. Each unit is equipped with a stabilized and linearized multichannel analyzer for the measurement of gamma spectra and optionally a He3 neutron detector. The flexible hard- and software architecture allows the simple integration of a variable number of detectors, even with different volumes. With this technique, spectroscopical screening of large areas, e.g. airports or comparably sensitive objects, can be established by an individual combination of these detectors. The general outline of the nuclide identification algorithm is presented. In the context of medical isotopes, the importance of correct reference data that incorporates the scattering effects of human bodies is clarified. A special focus is drawn to the localization of nuclear sources. The model, corresponding simulations and its applications are depicted. Different tests and verification measures are described that refer to the nuclide identification and the source localization as well as to the spectral quality of the detectors. A finished real application is presented that combines the tested algorithms and has proven its reliability on different occasions.

Claus-M. Herbach, Yong Kong, Ralf Lentering, Marcus Neuer, Guntram Pausch, Cristina Plettner, Kai Ruhnau and Jürgen Stein, Nuclear Science Symposium Conference Record (NSS/MIC), Dresden, 2008

 

Abstract: A simulation technique has been developed to study the performance of nuclide identifying gamma detector units operating under a variety of different conditions. The studies are related to nuclide identification based on a template matching algorithm which has been well established, in particular, for the analysis of low statistics measurements. Results are presented for hand-held devices equipped with NaI(Tl) and LaBr3(Ce3+) scintillation detectors, respectively

Pitch angle scattering and effective collision frequency caused by stochastic magnetic fields

Marcus Neuer and Karl-H. Spatschek, AIP Physics of Plasmas 15, 022304, 2008

 

The motion of charged particles in a plasma with stochastic magnetic field lines is investigated on the basis of the so-called A-Langevin equation. In contrast to the well-known perpendicular (to an external magnetic field)transport here the parallel transport is considered. The two cases of a strong guiding field and a weak mean magnetic field respectively are investigated. The A-Langevin equation is solved under the assumption that the Lagrangiancorrelation function for the magnetic field fluctuations is related to the Eulerian correlation function (in Gaussian form) via the Corrsin approximation. The latter is justified for small Kubo numbers. Generalizations to large Kubo numbers are discussed. It is shown that the magnetic field fluctuations are the source of diffusive motion along a strong guiding field even if binary collisions are absent. The case of small (or vanishing) mean fields is also investigated in the quasilinear limit. An effective collision frequency is derived which is consistent with the result for perpendicular quasilinear diffusion in strong guiding fields. The analytical results are checked by numerical simulations of the A-Langevin equation.

Diffusion of test particles in stochastic magnetic fields in the percolative regime

Marcus Neuer and Karl-H. Spatschek, Physical Review E 74, 036401, 2006

 

Abstract: For stochastic magnetic flux functions with percolative contours the test particle transport is investigated. The calculations make use of the stochastic Liouville approach. They start from the so-called A-Langevin equations, including stochastic magnetic field components and binary collisions. Using the decorrelation trajectory method, a relation between the Lagrangian velocity correlation function and the Eulerian magnetic field correlation is derived and introduced into the Green-Kubo formalism. Finite Larmor radius effects are included. Interesting results are presented in the percolation regime corresponding to high Kubo numbers. Previous results are found to be limiting cases for small Kubo numbers. For different percolative scenarios the diffusion is analyzed and strong influences of the percolative structures on the transport scaling are found. The finite Larmor radius effects are discussed in detail. Numerical simulations of the A-Langevin equation confirm the semianalytical predictions.

Finite Larmor Radius contributions to anomalous transport in plasmas with stochastic magnetic fields

Marcus Neuer, Dissertation, Heinrich-Heine-Universität Düsseldorf, 2004

Abstract: Anomalous transport of charged particles in a collisional stochastic plasma is investigated on the basis of the A-Langevin equation. The latter is a stochastic differential equation describing the motion of a particle that experiences collisions and a stochastic magnetic field. Contrary to previously used guiding center models, here finite Larmor radius effects are taken into account. Two different approximation methods are applied to obtain the Lagrangian velocity correlation function from the solution of the A-Langevin equation, distinguished in terms of a dimensionless parameter called the Kubo number, which measures the degree of magnetic turbulence. The first one, the Corrsin approximation, is a widely used straightforward technique to relate the Lagrangian correlation, which is determined in the co-moving frame of reference, with the common, spatially dependend Eulerian correlation. Differential equations for the mean square diplacement and the diffusion coefficient are obtained from the Green-Kubo formalism. The quasilinear limit is discussed and estimates for the Larmor radius effects are presented. The well-known Rechester-Rosenbluth regime is derived and the influence of the Larmor radius is discussed in detail...

Chirped solitons as attractors for short light pulses

Marcus Neuer, Zhonghao Li and Karl-H. Spatschek, Physical Review E 70, 056605, 2004

 

Abstract: Nonlinear chirped pulse solutions are shown to exist as stable attractors for short light pulses in driven and damped systems. The attractors are determined for systems of different complexity, from simple gain and damping modelings up to the inclusion of higher-order dispersion, Raman processes, and delayed nonlinear responses. The chirped attractors, their stability, as well as the attractor basins can be determined analytically. The analytical predictions are in excellent agreement with numerical simulations.
