Novel ultrathin TiO2–Cu nanoparticulate films sputtered by highly ionized pulsed plasma magnetron sputtering (HIPIMS) lead to faster bacterial inactivation compared to more traditional sputtering approaches with an appreciable metal saving. HIPIMS sputtering induces a strong interaction of the TiO2–Cu-ions (M ) with the polyester surface due to the high fraction and density of M-ions interactin...

The morphology and grown mechanism of aluminum films from 3nm to 30nm in thickness onto thermal SiO2 on Si(100) substrates have been studied by atomic force microscopy and TCR measurement. The thin films prepared by dc magnetron sputtering at 450°C is composed of islands of aluminum. The island density, distribution of island size, height, and shape are studied.

This paper describes the design and the characterization of an 8 slots resonant cavities Magnetron, which undergoes the thermal-structural effects due to the cathode heating. The proposed study involves Thermal Stress (TS), Eigen-frequency (EF) and Particle Tracing (PT) analysis based on a COMSOL Multiphysics (MP) simulation. Magnetrons are well known and more utilized High Power (HP) Radiofreq...

We report measurements of the azimuthal emission nonuniformity of a gyrotron's thermionic cathode as determined from two experiments, one which determines the total emission and one which scans the emitted beam using a rotating probe. In the total emission experiment, which measured the total collector current over a range of voltages, the cathode's total work function spread was found to be 0....

Flake graphite has excellent explosive electron emission performance for its plenty surface micro-bulges and high graphitization degree, but advantages have rarely been studied in relativistic magnetrons. In this paper, flake cathodes with different fineness were used coaxial diodes magnetrons, the influence of microstructure cathode on magnetron is demonstrated first time. The result showed th...
