    electron beam
  • A stream of electrons in a gas or vacuum

  • beam: a group of nearly parallel lines of electromagnetic radiation

  • Cathode rays (also called an electron beam or e-beam) are streams of electrons observed in vacuum tubes, i.e. evacuated glass tubes that are equipped with at least two metal electrodes to which a voltage is applied, a cathode or negative electrode and an anode or positive electrode.

  • (Electron Beams) are streams of high-energy electrons that travel at relativistic speeds.  The effect on a target is identical to that of beta radiation.





    equipment
  • The process of supplying someone or something with such necessary items

  • Mental resources

  • The act of equipping, or the state of being equipped, as for a voyage or expedition; Whatever is used in equipping; necessaries for an expedition or voyage; the collective designation for the articles comprising an outfit; equipage; as, a railroad equipment (locomotives, cars, etc.

  • The necessary items for a particular purpose

  • A tool is a device that can be used to produce or achieve something, but that is not consumed in the process. Colloquially a tool can also be a procedure or process used for a specific purpose.

  • an instrumentality needed for an undertaking or to perform a service





    welding
  • Join together (metal pieces or parts) by heating the surfaces to the point of melting with a blowpipe, electric arc, or other means, and uniting them by pressing, hammering, etc

  • Unite (pieces of plastic or other material) by melting or softening of surfaces in contact

  • (weld) join together by heating; "weld metal"

  • Forge (an article) by such means

  • fastening two pieces of metal together by softening with heat and applying pressure

  • (weld) dyer's rocket: European mignonette cultivated as a source of yellow dye; naturalized in North America











electron beam welding equipment - Nanofabrication Using




Nanofabrication Using Focused Ion and Electron Beams: Principles and Applications (Oxford Series in Nanomanufacturing)


Nanofabrication Using Focused Ion and Electron Beams: Principles and Applications (Oxford Series in Nanomanufacturing)



Nanofabrication Using Focused Ion and Electron Beams presents fundamentals of the interaction of focused ion and electron beams (FIB/FEB) with surfaces, as well as numerous applications of these techniques for nanofabrication involving different materials and devices.

The book begins by describing the historical evolution of FIB and FEB systems, applied first for micro- and more recently for nanofabrication and prototyping, practical solutions available in the market for different applications, and current trends in development of tools and their integration in a fast growing field of nanofabrication and nanocharacterization. Limitations of the FIB/FEB techniques, especially important when nanoscale resolution is considered, as well as possible ways to overcome the experimental difficulties in creating new nanodevices and improving resolution of processing, are outlined.

Chapters include tutorials describing fundamental aspects of the interaction of beams (FIB/FEB) with surfaces, nanostructures and adsorbed molecules; electron and ion beam chemistries; basic theory, design and configuration of equipment; simulations of processes; basic solutions for nanoprototyping. Emerging technologies as processing by cluster beams are also discussed.

In addition, the book considers numerous applications of these techniques (milling, etching, deposition) for nanolithography, nanofabrication and characterization, involving different nanostructured materials and devices. Its main focus is on practical details of using focused ion and electron beams with gas assistance (deposition and etching) and without gas assistance (milling/cutting) for fabrication of devices from the fields of nanoelectronics, nanophotonics, nanomagnetics, functionalized scanning probe tips, nanosensors and other types of NEMS (nanoelectromechanical systems). Special attention is given to strategies designed to overcome limitations of the techniques (e.g., due to damaging produced by energetic ions interacting with matter), particularly those involving multi-step processes and multi-layer materials.

Through its thorough demonstration of fundamental concepts and its presentation of a wide range of technologies developed for specific applications, this volume is ideal for researches from many different disciplines, as well as engineers and professors in nanotechnology and nanoscience.
