Tungsten electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way.

A family’s day with Tungsten

 

Mother:

After breakfast with the children, mother leaves the home by car and drives to the hospital. Today she has a CT (computer tomography) inspection of her spine, where she constantly suffers from pain. She has these pains for months and is really happy, that she was able to fix this date at the hospital as their new computer tomograph is always occupied and it is not easy to get plugged in.

 CT(computer tomography)

The computer tomography is a medical instrument which produces 3-dimensional X-ray images of the area in question. Several X-ray tubes are contained. In such an X-ray tube we find an electron gun whose electrode is made of Tungsten and furthermore a rotating anode also made of Tungsten or a Tungsten-Rhenium alloy. The shielding of the whole machine is done by Tungsten heavy metal (as a replacement for Lead, which was used in earlier days).

Fortunately enough, the doctor indicated to her that nothing serious could be detected and she most probably only has to train her brace muscles to get rid of the pain.
