Tubes analyseurs et tubes récepteurs [...] La cible se présente sous la forme d'une plaque rectangulaire; c'est une feuille de mica [...] dont la face arrière est recouverte d'une pellicule d'argent d'épaisseur uniforme (plaque-signal) tandis que sur la face avant se trouve une couche de globules photoélectriques, électriquement isolés les uns des autres (mosaïque). Pour former ces éléments photoélectriques, la plaque est tout d'abord argentée uniformément, puis elle subit un craquelage par étuvage avant d'être placée dans l'ampoule. Ensuite, tandis que le vide est fait, l'argent est légèrement oxydé en même temps qu'une couche monomoléculaire de césium est projetée sur lui. [...] La plaque-signal étant séparée des globules par un diélectrique, chacun d'eux forme un condensateur élémentaire avec cette plaque-signal. 1, record 1, French, - plaque%2Dsignal

The detector cell consisted of two circular plates. One was a 0. 0005-in nickel foil disk functioning as the sensor plate; the other, a 0. 002-in. gold foil disk, is called the vibrating plate. The gold disk is vibrated at 12 cps to produce alternating current readings for the oscilloscope, whereas the nickel sensor is thermically cycled by current surges. A 0. 10-in. mica spacer separates the plates so that vapor can be passed between them. 1, record 2, English, - vibrating%20plate
