KÍSÉRLETEK ELEKTRONCSŐVEL

•  Introduction to electron optics Cathode rays and deflecting fields can be used to magnify shadow images in a manner analogous to an optical lens system. With the help of this supplement, the experiment: Maltese-Cross ... tovább

Electrons in a fine-beam tube are deflected into a circular path by a uniform magnetic field. The tube contains neon gas at a precisely defined pressure so that gas atoms become ionised by collision with electrons along the path thus ... tovább

•  Investigating the deflection of an electron beam in an electric field. •  Investigating the deflection of an electron beam in a magnetic field. •  Calibrating the frequency control of the sawtooth ... tovább

In the experiment, two identical current-carrying coils are placed outside the Braun tube, and the deflection of the electron beam in the magnetic fields of the coils is observed on the tube’s fluorescent screen as shifts of the ... tovább
