Abstract Single crystalline tungsten samples were irradiated by He, D, and H at room temperature, with a calculated damage level in the peak maximum up to 0.04 dpa He 0.5 dpa. The dislocation structure of whole zone was investigated perpendicular surface Transmission Electron Microscopy (TEM) under four different two-beam diffraction conditions g = −200, 020, −110, 110 close [100] axis, taking ...

background: solid targets that consist of powder and electrodeposited targets are used commonly to produce radionuclides by accelerators. since silver is easily electrodeposited in cyanide baths and has a very excellent thermal conductivity, the electrodeposited target is preferable to produce 109cd. to avoid cracking or peeling of the target during bombardment, it should have a level surface a...

The electric properties of polymers are increasingly important in a wide range applications such as sensors, energy storages, microelectronics, and filtration membranes among others. In this work, the effect multi-energetic Au ion implantation on graphene oxide (GO), polyimide (PI), polyethylene terephthalate (PET) polylactide (PLLA) elemental, chemical, structural end is presented with potenti...

Neon abundance and isotopic composition measurements are now done for all 4 arms of the Genesis concentrator gold cross (consisting of gold on stainless steel; AuSS). The data prove that the entire concentrator target was radially homogeneously irradiated (Fig. 1). An implantation experiment showed, however, that AuSS, characterized by a rough surface, experienced a significantly larger backsca...

In this paper, Shockley-Read-Hall (SRH) lifetime depth profiles in the drift layer of 10 kV SiC PiN diodes are calculated after MeV proton implantation. It is assumed that carbon vacancy will be domination trap for charge carrier recombination and SRH with defect parameters from literature proton-induced distributions deduced SRIM calculations. The imported to Sentaurus TCAD static dynamic simu...

The compressive strain induced work function modulation in boron nitride nanosheets (BNNS) has been studied. arose due to the irradiation of 30 keV Au beam on thin films BNNS. Before BNNS was characterized by Raman spectroscopy, UV-Vis where using Tauc plot bandgap chemically synthesized from commercial hBN powder calculated as well layer numbers also quantified an empirical relation exploiting...

KY(WO4)2 represents an outstanding host material for fabricating both bulk and waveguide lasers, when doped with different rare-earth elements. Ion implantation can be regarded as a universal tool for fabricating low-loss waveguide structures in optically active oxide materials [1]. In this contribution we report, for the first time to our knowledge, results obtained when implanting light ions,...

The storage of Weapons Grade Plutonium (WGPu) pits has prompted this study of the effects of alpha irradiation on stainless steel. Energetic alpha particles emitted from the decay of plutonium isotopes continually introduce helium into the metal cladding that surrounds the pits. The continuous introduction of helium into a metal leads to the degradation of its mechanical properties. The integri...

Abstract We have developed and successfully tested a low-pressure Time Projection Chamber (TPC) with Gas Electron Multiplier (GEM) readout for Accelerator Mass Spectrometry (AMS). AMS facility in Novosibirsk has problem of separating isobar ions different chemical elements that the same atomic mass. The typical example is radioactive isotopes 10 Be B are used to date geological objects at time ...
