Book excerpt: Bachelor Thesis from the year 2015 in the subject Physics - Nuclear Physics, Molecular Physics, Solid State Physics, grade: 2,0, Technical University of Darmstadt (Institut fur Kernphysik), language: English, abstract: The NEPTUN tagger is a setup which uses LaBr3 detectors. The calibration of them is challenging since the channel-to-energy relation is not linear and energy drifts can occur. The quality of the calibration increases by using high-energy -ray sources. Neutron capture reactions (n, ) with lathanum, bromine and chlorine which provide energies up to 8.5MeV are investigated with experiments and simulations. A moderator can deaccelerate the neutrons and that is why it increases the cross section for these reactions. Therefore the moderator thickness is analysed for an polyethylene exemplary. A thickness between around 5 cm is indicated as best choice. The lanthanum and bromine in the detector provides sharp peaks, as shown in the experiments. Chlorine target adds additional peaks to the spectrum. It is now possible to build an efficient and compact calibration setup. Der NEPTUN-Tagger ist ein Messaufbau, der LaBr 3 -Detektoren benutzt. Die Kalibrierung derer ist herausfordernd, da die Kanal-zu-Energie-Relation nicht linear ist und Energieverschiebungen auftreten konnen. Die Kalibrierungsqualitat kann uber hochenergetische -Strahlen-Peaks gesteigert werden. Neutroneneinfangreaktionen (n, ) mit Lanthan, Brom und Chlor, welche Energien von bis zu 8.5MeV liefern, werden mittels Experimenten und Simulationen untersucht. Ein Moderator bremst Neutronen und kann daher den Wirkungsquerschnitt der Reaktionen erhohen. Aus diesem Grund wurde die Dicke des Moderators am Beispiel von Polyethlen untersucht. Es zeigte sich, dass eine Dicke von etwa 5 cm die beste Wahl ist. Lanthan und Brom im Detektor erzeugen scharfe Peaks wie die Experimente zeigten. Zusatzliche Peaks im Spektrum lieferte das Chlor-Target. Nun ist es moglich, eine effiziente und kompakte Kalibrieru"

Available in PDF, EPUB and Kindle. Book excerpt: This second open access volume of the handbook series deals with detectors, large experimental facilities and data handling, both for accelerator and non-accelerator based experiments. It also covers applications in medicine and life sciences. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Radioactivity Analysis is written by experts in the measurement of radioactivity. The book describes the broad scope of analytical methods available and instructs the reader on how to select the proper technique. It is intended as a practical manual for research which requires the accurate measurement of radioactivity at all levels, from the low levels encountered in the environment to the high levels measured in radioisotope research. This book contains sample preparation procedures, recommendations on steps to follow, necessary calculations, computer controlled analysis, and high sample throughput techniques. Each chapter includes practical techniques for application to nuclear safety, nuclear safeguards, environmental analysis, weapons disarmament, and assays required for research in biomedicine and agriculture. The fundamentals of radioactivity properties, radionuclide decay, and methods of detection are included to provide the basis for a thorough understanding of the analytical procedures described in the book. Therefore, the Handbook can also be used as a teaching text. - Includes sample preparation techniques for matrices such as soil, air, plant, water, animal tissue, and surface swipes - Provides procedures and guidelines for the analysis of commonly encountered na
