Applications of cosmic-ray (CR) muons have grown in numbers the last decade. Measurements flux attenuation (radiography) and scattering angles (tomography) CR been successfully applied to inspection or monitoring large natural civil structures, search for heavy metals container trucks, control nuclear wastes, much more. In present work, a new Monte Carlo generator muons, called EcoMug specifica...
Introduction A 75-year-old woman with a dual-chamber pacemaker was seen in the cardiology clinic for possible device malfunction. The patient’s device identification card revealed that a pacemaker from “Manufacturer A” was implanted in 2001. However, device interrogation using the corresponding programmer failed to communicate with the device. Given the age of the device, complete depletion of ...
A lightning surge generator generates a high-voltage surge with a 1.2μs rise time. The generator fed a spark gap of two pointed electrodes at 0.7 to 1.2 m distances. Gap breakdown occurred between 0.1 and 3μs after the maximum generator voltage of approximately 850 kV. Various scintillator detectors with different response times recorded bursts of hard radiation in nearly all surges. The bursts...
It is known from experiments that the radiated x-ray energy appears to exceed the calculated implosion kinetic energy and Spitzer resistive heating [C. Deeney, Phys. Rev. A 44, 6762 (1991)] but possible mechanisms of the enhanced x-ray production are still being discussed. Enhanced plasma heating in small-diameter wire arrays with decreased calculated kinetic energy was investigated, and a revi...
A new type of rotating anticathode X-ray generator, where an electron beam of up to 60 keV irradiates the inner surface of a U-shaped Cu anticathode, has achieved a beam brilliance of 130 kW mm(-2) (at 2.3 kW). A higher-flux electron beam is expected from simulation by optimizing the geometry of a combined-function-type magnet instead of the fringing field of the bending magnet. In order to min...
