XRay Tube $117.9 High Quality Content by WIKIPEDIA articles An Xray tube is a vacuum tube that produces Xrays. They are used in Xray machines. Xrays are part of the electromagnetic spectrum, an ionizing radiation with wavelengths shorter than ultraviolet light. Xray tubes evolved from experimental Crookes tubes with which Xrays were first discovered in the late 1800s, and the availability of this controllable source of Xrays created the field of radiography, the imaging of opaque objects with penetrating radiation. Xray tubes are also used in CAT scanners, airport luggage scanners, Xray crystallography, and for industrial inspection. As with any vacuum tube, there is a cathode, which emits electrons into the vacuum and an anode to collect the electrons, thus establishing a flow of electrical current, known as the beam, through the tube.

What decides whether current will flow or not in a vacuum tube? In a transistor?
tube: the gate voltage
Junction transistor: base current
FET: gate voltage
It's a lot more complicated than that, but this is the simplified version.
edit: thanks, dogs, grid voltage.... mind is going...
