An advanced digital measurement system for Coincidence Doppler broadening (CDB) technique is presented. Traditional CDB setups are based on shaping amplifiers and multi parameter multi-channel analyzers (MCA). We replaced them by 14-bit data acquisition card (DAQ). Replacing multi-parameter MCA by DAQ was realized also by several groups before, but in our setup the signal shaping tasks are performed digitally by software in a personal computer. Signals from high purity (HP) Ge detectors are sampled at preamplifier outputs. Pulse shaping is realized by a trapezoidal filter.

We present here two simple instruments for the study of double photoionization processes at threshold. They rely on the coincidence measurement of two near-zero energy electrons, which are collected by a penetrating field technique, and energy selected either by time-of-flight analysis (1st setup) or by electrostatic filtering in a hemispherical analyzer (2nd setup). Performance of the apparatus is demonstrated on Ar threshold double photoionization, and used to show the importance of two step double photoionization routes at Ar and Kr double ionization threshold.

The aim of this paper is to initiate the study of coincidence best proximity point problem in the setup of generalized metric spaces. Some results dealing with existence and uniqueness of a coincidence best proximity point of mappings satisfying certain contractive conditions in such spaces are obtained. An example is provided to support the result proved herein. Our results generalize, extend, and unify various results in the existing literature.

Es wird ein Verfahren zur Energiekalibrierung von Niedrig-Z-Szintillatoren vorgestellt.
Jenes basiert dabei auf einem roboter-unterstütztem Weitwinkel-Compton-Aufbau. In diesem werden die koinzidenten Ereignisse von Compton-gestreuten Photonen in einem HPGe-Detektor und einem Niedrig-Z-Szintillator erfasst und die Messdaten zur Energiekalibrierung des letzteren genutzt. Eine Bestimmung von Compton-Kanten für das Szintillatormaterial ist dabei nicht zwingend notwendig. A technique for the energy calibration of low-Z scintillators is being presented.
It is based on a robot-supported wide-angle Compton setup. In this the coincident events of photons being Compton-scattered in a HPGe detector and a low-Z scintillator are being recorded and the generated measurement data used for energy calibration of the latter. A determination of Compton edges in the scintillator material is not necessarily needed.

AbstractMulti-particle momentum imaging experiments are now capable of providing detailed information on the properties and the dynamics of quantum systems in Atomic, Molecular and Photon (AMO) physics. Historically, Otto Stern can be considered the pioneer of high-resolution momentum measurements of particles moving in a vacuum and he was the first to obtain sub-atomic unit (a.u.) momentum resolution (Schmidt-Böcking et al. in The precision limits in a single-event quantum measurement of electron momentum and position, these proceedings [1]). A major contribution to modern experimental atomic and molecular physics was his so-called molecular beam method [2], which Stern developed and employed in his experiments. With this method he discovered several fundamental properties of atoms, molecules and nuclei [2, 3]. As corresponding particle detection techniques were lacking during his time, he was only able to observe the averaged footprints of large particle ensembles. Today it is routinely possible to measure the momenta of single particles, because of the tremendous progress in single particle detection and data acquisition electronics. A “state-of-the-art” COLTRIMS reaction microscope [4–11] can measure, for example, the momenta of several particles ejected in the same quantum process in coincidence with sub-a.u. momentum resolution. Such setups can be used to visualize the dynamics of quantum reactions and image the entangled motion of electrons inside atoms and molecules. This review will briefly summarize Stern’s work and then present in longer detail the historic steps of the development of the COLTRIMS reaction microscope. Furthermore, some benchmark results are shown which initially paved the way for a broad acceptance of the COLTRIMS approach. Finally, a small selection of milestone work is presented which has been performed during the last two decades.

In Field-Programmable Gate Array (FPGA) Technologies for High Performance Instrumentation, 17–41. IGI Global, 2016. http://dx.doi.org/10.4018/978-1-5225-0299-9.ch002.
The chapter describes how to develop algorithms for Gamma ray spectrometry portable instruments and then to implement them on FPGA devices as hardware platform. At first we consider the development of more accurate spectrum evaluation programs including pileup detection and recovery, dead time correction, coincidence summing and resolution enhancement algorithms which are implemented in MATLAB. The input signals are obtained through experimental setup or simulated model. Four different approaches are studied and evaluated for peak pileup problem within a spectroscopy system. In addition, x-ray spectrum evaluation enhancements are carried out and several algorithms are developed and compared. Hardware implementation using Xilinx DSP Boards as well as further improvements and modifications are discussed.

Since the nuclear energy industry in China has developed rapidly, the demand for spent fuel reprocessing is becoming more and more distinct. In a reprocessing facility, power supply system (PSS) is important for operation-stability and safety-guarantee of the whole facility. Therefore, the reliability of the PSS deserves in-depth investigation and analysis. Fault tree (FT) methodology is the most accustomed methodology for system-reliability analysis and it has been standardized and applied widely. GO methodology is another effective methodology for system-reliability analysis but it has not been applied widely. In this work, GO methodology was applied to analyze the reliability of the PSS in a typical reprocessing facility. First, for modeling expediently, based on the fact that tie breakers are set in the system, tie breaker operator was defined by myself. Then, GO methodology modeling and quantitative analysis were performed, minimal cut sets (MCSs) and average unavailability of the system were obtained. Finally, parallel analysis between GO methodology and fault tree methodology was also performed. The results from the two methodologies are completely coincident. The results of this work show the following two points: 1. Setup of tie breakers in the PSS of the reprocessing facility is rational and necessary; 2. For reliability analysis of the PSS of the reprocessing facility, parallel with fault tree methodology, GO methodology has two distinct advantages: Its modeling is much easier and its chart is much more succinct.
