| The ion mobility cell is doped with ions produced by a corona discharge ionisation source. |
| He discovered that power lines produce electrically charged particles called corona ions. |
| But the hotter hydrogen in the chromosphere and corona above it is madly emitting at the same wavelength. |
| The internal capsule and corona radiata have been exposed by removal of the corpus callosum, caudate nucleus, and diencephalon. |
| An X-ray telescope filters out all the light from the Sun except X rays, and what is left is mostly the solar corona. |
| The hood of the truck blazed with dazzling corona discharges and St. Elmo's fire coruscated around the headlamps and other metal fixtures. |
