Wondrous Words Wednesday

Wondrous Words Wednesday

My word today comes from the book, Orphan #8.

Coolidge tube- is named after President Calvin Coolidge. It is an x-ray tube in which the cathode consists of a tungston wire spiral surrounded by a focusing cup.

    I wonder if it was some primitive form of x-ray? Or used for a specific purpose?
