Neutron induced reaction cross-section measurements display special interest both for fundamental research in the Nuclear Physics field and many practical applications. The Institute of Nuclear and Particle Physics (INP) of the National Centre for Scientific Research Demokritos (N.C.S.R. “D”) hosts the 5.5 MV T11/25 Van de Graaff accelerator, which is the only accelerator used in Greece for research purposes. This accelerator recently underwent a major upgrade, including the installation of a new pelletron charging system, two new ion sources, a new gas stripper and beam optics. This neutron facility can produce quasi-monoenrgetic neutron beams in the energy range ∼16-19 MeV via the 3 H(d,n)4 He (D-T) reaction, employing a tritiated Titanium target (TiT). The neutron induced cross sections of a total of nine reaction channels have been experimentally measured in the present work, via the activation technique, using enriched Ge targets. These targets produce more accurate cross-section results, in comparison with the - most commonly used in bibliography - nat Ge samples, since they do not suffer from contaminating reactions that produce the same residual nucleus. Monte Carlo simulations were also performed via the combined use of MCNP5 and NeuSDesc codes for the simulation of the neutron beam.

“…For the study of neutronemitting processes, an array of sixteen 3 He-gas-filled neutron counters is also provided [193]. The multipurpose large-volume scattering chamber and the deuterium-filled gas cell for the generation of quasi-monochromatic neutrons are among the experimental tools that are most frequently used [189]. The primary objective of the Nuclear Astrophysics program at TAL is to further clarify nuclear physics aspects of the p-process [189].…”

The primary objective of the Nuclear Astrophysics program at TAL is to further clarify nuclear physics aspects of the p-process [189]. The solar system p-nuclei abundances still pose a challenge for all p-process nucleosynthesis models, which fail to reproduce them, especially in the case of the light p-nuclei.…”

Small-scale facilities play a significant role in the landscape of nuclear physics research in Europe. They address a wide range of fundamental questions and are essential for teaching and training personnel in accelerator technology and science, providing them with diverse skill sets, complementary to large projects. The current status and perspectives of nuclear physics research at small-scale facilities in Europe will be given.

“…A recent topical collection of articles summarized a significant portion of the existing small and medium sized accelerator infrastructures in Europe [9]. When it comes to IBA facilities, laboratories at the Universities of Lisbon [10] and Florence [11], the Nuclear Physics institute of the Czech Academy of Sciences [12], the Institute of Nuclear and Particle Physics in Athens [13] and the Atomki Accelerator Centre in Hungary [14] among others were described. We complement those works here with a description of the Tandem Laboratory at Uppsala University, a Swedish national research infrastructure.…”

Ion accelerators have demonstrated tremendous versatility in their research applications throughout several decades. Starting predominantly as nuclear physics tools, they subsequently provided novel insights into fundamental atomic physics. Nowadays small and medium size accelerators are routinely employed in several branches of materials science. As research questions increasingly drive the need for analyses and material modification experiments performed in-situ and/or in-operando, facilities must adapt to service such a need. In this work, we highlight capabilities for in-situ and in-operando composition depth profiling and materials modification, developed with instrumentation at the Tandem Laboratory at Uppsala University. An overview of available ion sources and accelerators is given. We then exemplify the specific capabilities of the available end stations for materials synthesis, sample modification and device operation either during simultaneous ion beam based characterization or with such characterization performed in-situ before and after the application of various modification steps. Describing specific recent examples and potential future applications, we illustrate the impact of the present national research infrastructure.
