During neutron irradiation in Prompt Gamma Neutron Activation Analysis (PGNAA), absorption of thermal neutrons by the detector is inevitable. Therefore, the final gamma spectrum will be a mixture of natural background, delayed and prompt gamma-rays originated from different setup parts including moderator, sample and detector itself. A Delayed-Gamma-Monte-Carlo Code (DGMC) was written to...

Crosstalk and afterpulsing in silicon photomultipliers can strongly limit the photon-counting resolution and dynamic range of the sensors. In this work we present a method and measurements to separate the afterpulse and delayed crosstalk components of the delayed correlated pulses in the silicon photomultiplier signal. On one hand, the motivation was to understand the relative contributions of...

The CsI-Silicon Particle detector for Heavy ions Orbiting in Storage rings (CsISiPHOS) was designed and developed for β-decay studies at the Experimental Storage Ring (ESR) and as a prototype of the in-pocket detectors for the ILIMA programme at the future Collector Ring (CR) at FAIR. The detector serves as a ΔE/E telescope to be used for detection and identification of each incident ion....

The residual nuclei yields are of great importance for the estimation of basic radiation-technology characteristics (like a total target activity, production of long-lived nuclides etc.) of accelerator driven systems planned for transmutation of spent nuclear fuel and for a design of radioisotopes production facilities. Experimental data are also essential for validation of nuclear codes...

In fission, the investigation of different experimental observables has shown evidences that the viscosity of the medium changes with the deformation, but also with the nuclear temperature [1]. However, these ideas are still under debate because there conclusions could be biased by the experimental conditions. We propose then to investigate these effects with complete kinematic measurements of...

Two-body orbital electron-capture (EC) decay of stored and cooled highly charged ions has been studied in the Experimental Storage Ring (ESR) at GSI Helmholtzzentrum in Darmstadt, Germany. The H-like 142Pm60+ ions were produced by fragmentation of 600 AMeV 152Sm ions in a Be-target. The 142Pm60+ fragments were separated in-flight by the FRagment Seperator (FRS), injected into the ESR storage...

The ALTO facility in Orsay consists of two accelerators within the same installation. A Tandem accelerator (15 MV) is dedicated to the production of stable beams (ions and cluster) for nuclear- and atomic-physics studies. A linear electron accelerator (50 MeV) is dedicated to the production of radioactive beams using the photo-fission on UCx targets. The provided stable and radioactive ions...

The design of the Generation IV lead-cooled fast reactors and of the future accelerator-driven systems require the knowledge of neutron inelastic cross sections on 206Pb with a precision of the order of 5%. An extended experiment consisting of two largely independent measurements was conducted at the GELINA neutron source operated by EC-JRC-IRMM. We present in detail the experimental technique...
