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.
