An electron beam ion source (EBIS) is a device used in atomic physics to produce highly charged ions by bombarding atoms with a powerful electron beam. Its principle of operation is shared by the Electron beam ion trap.
Famous quotes containing the words beam and/or source:
“What do we plant when we plant the tree?
We plant the ship that will cross the sea,
We plant the mast to carry the sails,
We plant the planks to withstand the gales—
The keel, the keelson, and beam and knee—
We plant the ship when we plant the tree.”
—Henry Abbey (1842–1911)
“There often seems to be a playfulness to wise people, as if either their equanimity has as its source this playfulness or the playfulness flows from the equanimity; and they can persuade other people who are in a state of agitation to calm down and manage a smile.”
—Edward Hoagland (b. 1932)
