Set of three hot cathode crookes tubes CT-3NP

B10-7242-X0

【Product Description】

A set of three kinds of a hot cathode crookes tubes

【Overall Advantages to Users】

Three typical hot cathode crookes tubes are in the set. One is a hot cathode crookes tube with a maltese cross, second one is a hot cathode crookes tube for the magnet deflection, third one is a hot cathode crookes tube with deflection plates.

【To all users】

  • The hot cathode crookes tube with a maltese cross can demonstrate linearity in emitted electron.
  • The hot cathode crookes tube for magnet deflection can demonstrate that the emitting electron beam can be bent by magnetic field.
  • The hot cathode crookes tube with deflection plates can demonstrate that the emitting electron beam can be bent by electric field.

【To teachers】

  • The type of hot cathode tube is a safe because of no X-ray emitting compaired with the cold cathode tube. Because the cathode rays emitting mechanism is different compared to the cold cathode crookes tube due to using an heated electrical filament.
  • The demonstration time of the cathode rays emitted in the tube can be kept observing safer and longer in comparison to the cold cathode tube.

【To students】

  • Possible to clearly observe cathode ray even in a classroom with normal illumination level because the end of the tube is painted with fluorescent.
  • Easy to confirm how cathode ray is affected by electric or magnetic field.
