OSNI Contest N°4: the solution

Today we reveal the solution for this last OSNI of the academic year!

Coolidge tube to radiator

Manufactured by GAIFFE-GALLOT and PILON, this device produces X-rays for X-ray imaging. Under the impact of the electrons emitted by the cathode, the tungsten atoms in the anode are excited. In order to recover their fundamental energy level, they emit high-energy X-rays, which are reflected in all directions and pass through the glass wall.

The draw designated Melina who wins a prize.

Many thanks to all participants!
