The violation of Baryon Number, $\mathcal{B}$, is an essential ingredient for the preferential creation matter over antimatter needed to account observed baryon asymmetry in universe. However, such a process has yet be experimentally observed. HIBEAM/NNBAR %experiment program proposed two-stage experiment at European Spallation Source (ESS) search number violation. will include high-sensitivity searches processes that violate by one or two units: free neutron-antineutron oscillation...
We have measured fission fragment-mass yields for neutron-induced of $^{232}\mathrm{Th}$ and $^{238}\mathrm{U}$ at energies 32.8, 45.3, 59.9 MeV. The experiments were done quasimonoenergetic neutron beams the Cyclotron Research Center Louvain-la-Neuve. To detect fragments, a multisection Frisch-gridded ionization chamber was used. measurement data analysis techniques are discussed in detail. obtained mass compared to model calculations with intermediate-energy nuclear reaction code MCFX....
In this paper we discuss some general aspects of Stokes profile inversion in prominences using principal component analysis (PCA). First, address the problem departure formation He I D3 from optically thin approximation, dealing a heuristic way with two visible components line, which are differently affected by radiative transfer. This modified does not alter recently published results on magnetic structure quiescent prominences, particular confirming presence fields significantly larger...
Covers advancements in spacecraft and tactical strategic missile systems, including subsystem design application, mission analysis, materials structures, developments space sciences, processing manufacturing, operations, applications of technologies to other fields.
In Frisch grid ionization chambers special attention must be paid to the operating voltages in order avoid unwanted collection of electrons on grid. Collection will lead a decreased signal noise ratio and consequently deteriorated energy resolution. Furthermore, systematic errors determination angular distribution introduced. Theoretical formulas for minimized were derived by Bunemann et al. [3] case consisting plane parallel wires. No such exist other geometries careful calibration...
Spacecraft returning scientific samples or humans from space must be capable of surviving re-entry and landing in a desired location. Traditionally, this has been accomplished via propulsive de-orbit burn. However, it is not always possible to mount propulsion system on board satellite capsule. In the case small satellites deployed International Space Station, for example, on-board systems are forbidden safety reasons. Our work proposes new technological solution re-entering spacecraft...
Over the past years an experimental programme has been run at neutron beam of The Svedberg Laboratory with aim to study light-ion production induced by 96 and 175 MeV neutrons for a wide variety targets. measurements have conducted using Medley facility which allows measurement p, d, t, He-3 alpha fixed angles (from 20 160 degrees in steps degrees) over dynamic range. An overview results obtained now finished campaign will be given. Since 2007 we running C, O, Si, Fe, Bi U as target...
Spacecraft equipped with the capability to vary their ballistic coefficient can use differential drag as control force perform propellant-less relative maneuvers. Because atmospheric is proportional density, uncertainty in density makes generation and tracking of drag-based guidances difficult. Spatio-temporal resolution, or mapping information altitude time, shown this work improve estimation from forecasted for spacecraft LEO. This achieved by propagating simulated orbits two using...
The 10B(n,α) reaction cross-section is a well-established neutron standard for incident energies up to 1 MeV. However, above this energy limit there are only scarce direct (n,α) measurements available and these few experimental data showing large inconsistencies with each other. These discrepancies reflected in the evaluated libraries: ENDF/B-VII.1, JEFF-3.1.2 JENDL-4.0 excellent agreement 100 keV neutrons, whereas different libraries show differences MeV region. To address inconsistencies,...
We have measured double-differential yields of protons, deuterons, and tritons produced from carbon induced by 175 MeV quasi mono-energetic neutrons using the MEDLEY setup at TSL neutron beam facility.The data are used for benchmarking a high-energy nuclear file, JENDL/HE-2007, both intra-nuclear cascade (INC) model quantum molecular dynamics (QMD) calculations.
