Tesla Coil - Improving Radiographs

[39398.] — Tesla Coil. — No, to both queries. If your coil works badly, the Tesla will do worse. With a good steady running coil, the Tesla, as it increases the voltage, and also the oscillation frequency, enables a given coil to light up tubes which, owing to their high resistance, would be unworkable by the coil alone. But I am very doubtful whether, beyond this, any real advantage is gained-in other words, whether better radiographs are not to be obtained from a given coil by using a tube suitable to it, rather than by attempting to raise the voltage of the coil by the use of a Tesla to suit a higher voltage tube.
