Focused Ion Beam Micro Machining and Micro Assembly
The ability to manufacture and manipulate components at the micro-scale is critical to the development of micro systems. This paper presents the technique to manipulate micro/nano parts at the micro/nano-scale using an integrated Focused Ion Beam (FIB) system composed of scanning electron microscope, micro manipulator and gas injection system. Currently the smallest gears manufactured with trad...
متن کاملIon beam formation in a low-pressure geometrically expanding argon plasma
Supersonic ion beam formation has been observed in a geometrically expanding low-pressure inductively coupled argon plasma. It is found that the ion beam is only observed below 3 mTorr and only when the discharge is operated in inductive mode. The geometrical expansion of the plasma induces density and potential gradients leading to the ion beam formation. The ion beam energy increases with dec...
متن کاملElectron beam density measurements in shock waves in argon
An electron beam technique was used to measure density profiles of strong shock waves in argon with high accuracy. The experimental results are compared with the results of theoretical models. Of the models that are available in enough detail for comparison, the best agreement with experiment is shown by the direct simulation Monte-Carlo method (Bird 1968), assuming an inverse 12th power molecu...
متن کاملTop - Level Design and Preliminary Physical Analysis for the First Electron - Beam Micro - CT Scanner
A state of the art X-ray micro-CT scanner takes about 20 seconds to acquire a full dataset, which is too slow to capture the rapidly beating heart of small animals. We have been working to develop the first electron-beam micro-CT (EBMCT) prototype for cardiac imaging of the mice and rats. In this paper, we describe the background on electron-beam CT (EBCT) and emphasize the needs for EBMCT. The...
متن کاملRelativistic electron beam propagation in the earth's atmosphere- modeling results
Linear accelerators (linacs), capable of producing 5 MeV energy electron beams at 80 mA currents, are now down to a size that allow them to be flown on sounding rockets or balloons. This opens up new opportunities for atmospheric/ionospheric modification experiments where the mesosphere and thermosphere regions of the atmosphere can be perturbed down to 40 km altitude. In this paper beam propag...
