Skildring

SkildringCoolidge xray tube.jpg	Photo of a Coolidge x-ray tube, from the early 1900s. The cathode is on the left, heated by a separate current passing through a filament, which releases electrons into the tube. The anode target is on the right. A high voltage of several thousand volts applied between the cathode and anode accelerates the electrons into a beam which strikes the anode, generating x-rays. The surface of the anode is angled so the x-rays are emitted in a downward direction, through the side of the tube. Alterations: rotated image 90° clockwise, cropped out frame
