Ultra-thin 3D silicon sensors for neutron detection [PDF]

, 2012
We present a novel neutron detector based on an ultra-thin 3D silicon sensor with a sensitive volume only 10 µm thick. This ultra-thin active volume allows a high gamma-ray rejection, a key requirement in order to discriminate the signal coming from the ...

The neutron facility at NCSR ‘Demokritos’ and neutron activation research activities of NTUA

EPJ Techniques and Instrumentation, 2023
AbstractAt the 5.5 MV Tandem T11/25 Accelerator Laboratory of NCSR “Demokritos” quasi-monoenergetic neutron beams can be produced in the energy ranges ∼15–21 MeV by means of the 3H(d,n)4He reaction, ∼4–11 MeV via the 2H(d,n)3He reaction, ∼2.0–5.3 MeV using the 3H(p,n)3He reaction and ∼120–650 keV via the 7Li(p,n)7Be reaction.

Neutron activation analysis of the 30Si content of highly enriched 28Si: proof of concept and estimation of the achievable uncertainty

, 2014
We investigated the use of neutron activation to estimate the 30Si mole fraction of the ultra-pure silicon material highly enriched in 28Si for the measurement of the Avogadro constant.

Gravitoastronomy with neutron stars [PDF]

, 2004
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

Robust Electrocaloric Performance Enabled by Highly‐Polar Frustrated Nanodomains in NaNbO3‐Based Ferrodistortive Relaxor

Advanced Functional Materials, EarlyView.
P4bm framework in NaNbO3‐Ba(Ti, Hf)O3 ferrodistortive relaxor entails short‐range and highly‐polar ferrodistortive orders. The abundant highly‐polar orders facilitate to increase entropy change, and robust octahedral oxygen tilt enables to impede thermal perturbations.

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

Advanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

A new active thermal neutron detector

Radiation Protection Dosimetry, 2013
This communication presents the main results about the design and in-house fabrication of a new solid-state neutron detector, which produces a DC output signal proportional to the thermal neutron fluence rate. The detector has been developed within the framework of the 3-y project NESCOFI@BTF of INFN (CSN V).
