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 ...

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.

Armed with a cheap high voltage DC power supply he acquired from an online auction house, he started to power up his x-ray vacuum tube. A smaller power supply energizes the cathode and forms an ...

Research on anode-less solid-state lithium metal batteries reveals how metal interlayers influence lithium plating stability and electrochemical performance.
