Photograph of the general view of the statitron. The accelerating tube is encircled by corona rings.

The Generating Voltmeter is of the sectored disc type and was part of the control system of the statitron

The Statitron beam was analysed by a ninety degree annular magnetic spectrograph.The magnet had a radius of curvature of 30cm. The winding consisted of 30 layers of 15 B&S enamelled copper wire, about 4000 turns in all and could carry a current of 5 amperes.

The Pelletron is a high Voltage particle accelerator capable of producing 5Mev. The main tank contains the pelletron chain of metal pellets connected by insulating nylon links. The pellets are charged by induction and transported by a chain to the collecting dome. The tank is filled with sulfur hexafluoride a high voltage insulating gas

The Photograph is of the main 90 degree analysing magnet.

The beam line transports the accelerated particles to the site of the experimental apparatus. It is evacuated and may be one of many lines.

Apparatus to analyse the harmonic upper partials of c. Apparatus consists of 8 Helmhotz resonators (one missing) tuned to the upper harmonics of c. Each of the 8 resonators is connected with a manometric flame. All the manometric flames are observed by means of the rotating mirror. When a sound strikes the apparatus containing a tone to which one of the resonators is tuned, the image of the corresponding manometric flame is resolved by the rotating mirror into a series of separate images. The apparatus corresponds to a modern fourier spectrum analyser.
