THERE have now been described a number of moving-anode X-ray tubes, including the mercury-sealed type developed in this Laboratory 1–4, and their high performance may be regarded as established.

An x-ray tube is a simple device; a cathode emits electrons that strike a tungsten anode that emits x-rays. Most x-ray tubes, though, are relatively large with low-power mammography tubes being a ...

In a lithium-ion battery, the most extensively used battery worldwide, lithium ions move from the anode, the positive ... Photon Source (APS), a powerful X-ray machine at the Argonne National ...
