We have fabricated large current density cold cathodes based on the printed carbon nanotubes(CNTs), which are applied in the compact vacuum electron devices including X-ray sources and microwave tubes. The peak value of the cathode current in the diode structure driven by DC voltage is up to 19.88mA (current density: ∼2.51A/cm2), along with the fluctuations of the current smaller than 5.3% during...
This paper deals with the experimental comparison of forced convective heat transfer coefficient of CNT based nanofluids with the pure water in radiator which can be used for cooling of super computer. Carbon Nano Tube (CNT) based nanofluids with concentrations of 0.1% and 0.2% volume fractions have been used as test fluids. The liquid flow rate, ranging from 2–6 liter per minute (LPM) has been used...
The interaction between heavy liquid metals and pressurized water is an important issue both for fusion and fission reactors of new generation. The main results of past experimental activities aimed to investigate this issue are summarized in this paper. A simplified model has been developed to reproduce some of these results. In conditions of water injected in the liquid metal pool at low pressure,...
The construction of a new vacuum tube having a rating of 100 kw is described herewith.* This tube has been made possible by the development of water cooling and a satisfactory copper-glass seal.
