X-Ray Emission Characteristics of Vacuum Spark Plasmas Operated with Aluminium, Copper and Tin as Anode Materials
نویسندگان
چکیده
The X-ray emission characteristics of a vacuum spark device operated with anode materials of various atomic numbers were studied. The temporal evolution of the X-ray emission was recorded by using five channels of high-speed PIN X-ray diodes. A time-integrated X-ray spectrometer was used to record the spectral distribution of the X-ray emission. The electron temperatures of the aluminium, copper and tin vacuum spark plasmas were determined by using the X-ray absorption ratio method and were found to be in the range of 1 to 3 keV for aluminium plasma, 5 to 9 keV for copper plasma and 12 to 14 keV for tin plasma.

Fabrication of Nanostructured Cu matrix Nanocomposites by High Energy Mechanical Milling and Spark Plasma Sintering
Spark plasma sintering (SPS) is a sintering process that is capable of sintering hard worked powders in short times. This technique was used to fabricate bulk Cu and Cu-SiC nanocomposites. Pure Cu and mixed powders of Cu including 4 vol% of SiC nanoparticles were mechanically alloyed for 25 h and sintered at 750˚C under vacuum condition by SPS method. Microstructures of the materials were chara...

متن کاملMicroscopic high-speed liquid-metal jets in vacuum
The operation of microscopic high-speed liquid-metal jets in vacuum has been investigated. We show that such jets may be produced with good stability and collimation at higher speeds than previously demonstrated, provided that the nozzle design is appropriate and that cavitation-induced instabilities are avoided. The experiments with a medium-speed tin jet (u 60 m/ s, Re=1.8·10, Z=2.9·10 ) show...
