As the diagram on the right shows, the gallium (Ga+) primary ion beam hits the sample surface and sputters a small amount of material, which leaves the surface as either secondary ions (i+ or i−) or neutral atoms (n 0). The primary beam also produces secondary electrons (e −). As the primary beam rasters on the sample surface, the signal ...
Ion beam analysis (IBA) is an important family of modern analytical techniques involving the use of MeV ion beams to probe the composition and obtain elemental depth profiles in the near-surface layer of solids. IBA is not restricted to MeV energy ranges.
Fake news websites are those which intentionally, but not necessarily solely, publish hoaxes and disinformation for purposes other than news satire.Some of these sites use homograph spoofing attacks, typosquatting and other deceptive strategies similar to those used in phishing attacks to resemble genuine news outlets.
The United States Food and Drugs Administration is warning pet owners about a common medication given to pets to treat arthritis. The F.D.A. now says that the drug Librela may be associated with ...
More than 4 million Americans gouged by credit repair companies including Lexington Law and CreditRepair.com will soon collectively receive $1.8 billion in refund checks, the Consumer Financial ...
Sorry to break the news, but American cheese is not real cheese. It contains cheese, but not in large enough amounts to bear the title. The Food and Drug Administration (FDA) considers American ...
This makes for a beam of ions that is colder than the ions obtained from a magnetron. Heavy ions can be generated with an electron cyclotron resonance ion source. The use of electron cyclotron resonance (ECR) ion sources for the production of intense beams of highly charged ions has immensely grown over the last decade.
Sextupole electromagnet as used within the storage ring of the Australian Synchrotron to focus and steer the electron beam. In accelerator physics strong focusing or alternating-gradient focusing is the principle that, using sets of multiple electromagnets, it is possible to make a particle beam simultaneously converge in both directions perpendicular to the direction of travel.
