5224 Malta cross tube

With this tube it is possible to prove that cathode rays spread in a straight line. A Malta cross- like metal screen can be placed to intercept the cathode ray beam, producing a shadow zone on the screen which satisfies the laws of rectilinear propagation. To be used with 5cm Spark induction coil.
