This paper proposes a novel anomaly detection methodology for industrial systems based on Digital Twin (DT) ecosystems. In addition to DTs, conceived as digital representation of physical entity, this new concept DT focused modeling connections between behaviors. is called Snitch (SDT). The scope the SDT study variations behaviors and support anomalies them. behavior each entity characterized b...

A semiconductor solid state switch has been constructed and tested in the prototype extraction kicker pulse generator of CERN's Large Hadron Collider (LHC) [1]. The switch is made of 10 modified 4.5 kV, 66 mm symmetric GTO's (also called FHCT-Fast High Current Thyristor), connected in series. It holds off a d.c. voltage of 30 kV and conducts a 5 μs half-sine wave current of 20 kA with an initia...

background: several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. the aim of this study is to use backscattered neutron for landmine detection. materials and method...

The neutron-activation method was used for obtaining new experimental data on cross sections both for Ge(n,2n)Ge nuclear reaction and for some other (n,x) reactions on zirconium and germanium isotopes. The neutron generator was used as a neutron source. The samples in a shape of foils of natural germanium and zirconium were irradiated by DTneutrons. The following sources of uncertainties are ta...

We present recent work on the development of a microwave ion source that will be used in a high-yield compact neutron generator for active interrogation applications. The sealed tube generator will be capable of producing high neutron yields, 5 ·10 n/s for D-T and ∼ 1 ·10 n/s for DD reactions, while remaining transportable. We constructed a microwave ion source (2.45 GHz) with permanent magnets...
