11.   In the electron beam, the layer appeared about as transparent as an insect stuck in amber looks when examined with a flashlight.

12.   It also means that beams of matter, electron beams, for instance, can explore spaces far smaller than those accessible to ordinary light.

13.   It takes less than a second under the electron beam to kill E. coli bacteria in hamburger.

14.   It uses electron beams, not X-rays.

15.   Litton countered that the patent was primarily concerned with the way to use electron beams to make mirrors.

16.   Officials said they now are testing different methods of treating all mail, including using electron beams, X-ray technology and chlorine dioxide.

17.   One of the problems solved by using a very high-power laser, Umstadter said, is the inadvertent spreading and weakening of an electron beam during its initial acceleration.

18.   Photographs can be made by sound, heat, infrared radiation, electron beams, X-rays.

19.   Synchrotrons, like the Advanced Photon Source at Argonne National Laboratory near Chicago, create X-rays by using powerful magnets to bend an electron beam around a circular track.

20.   That measures how fast the electron beam in the monitor paints the image on the screen.
