Electrons are boiled off in the cathode (negative terminal). Electrons are sped up through accelerating plates (parallel plates with a potential difference). Electrons are deflected by a second (and third) set of deflecting plates. T. homson. BY: Noah Rushing, Kayla Zajac, Wade Scott, Kate Schlechtweg . Background . Full name Joseph John Thomson.

In 1895, Roentgen discovered the first example of ionizing radiation, x-rays. The key to Roentgens discovery was a device called a Crooke’s tube, which was a glass envelope under high vacuum, with a wire element at one end forming the cathode, and a heavy copper target at the other end forming the anode. When a high voltage was applied to the electrodes, electrons formed at the cathode would be pulled towards the anode and strike the copper with very high energy. Roentgen discovered that very penetrating radiations were produced from the anode, which he called x- rays (the symbol . Control panel . Extension arm. Tube head. Control panel. On/off switch.
