The focal length is dependent on (V2 — VJ, and the cylinders need not be of equal radii. v, v, < v2 v2 FIG. 13. 13 shows a simple aperture lens, the nature of which depends generally on the relative potentials of the electrodes. As well as focusing, this type of lens can also limit the width of the electron beam, just as a "stop" is used in geometrical optics. The electron gun arrangement of thermionic emitter and electrostatic focusing electrodes is sketched in Fig. 14: it is usually a combination of cylindrical and aperture lenses.

Students are referred to the instructions for this experiment supplied by the makers with every such valve. 1. Crystal structure Man has observed for centuries that certain substances have remarkably uniform shapes. Common salt is an example: if a few grains are observed through a magnifying glass they all appear as identical small cubes, no matter how or where the salt was refined. This regularity of shape was extra evidence to the scientists of many decades ago for the belief that macroscopic crystals were built up of microscopic particles, called atoms.

D. is very small. Problems 1. Why cannot light be used to photograph the atomic structure of a crystal? 2. 1 shows that iron, for instance, has two different crystal struc­ tures, dependent on the temperature. Can you suggest why this is? Suggest an experimental arrangement which might be used to show this. 3. 2, extending it to occupants of both sexes. ) 4. When an electron is free from the atom it can have any energy. Why is this not so within the atom ? 5. 2 point out all the metals, semiconductors and inert gases that you can see.
