The Plasma Contactor Unit discharges accumulated electrons(using a hollow cathode assembly that is provided as furnished equipment) from the International Space Station structure reducing the potential difference between the Station structure and the surrounding charged plasma environment. This reduction in potential eliminates arcing, thus preserving the exterior material properties of the space station structure. The electron discharge emission is facilitated by converting Xenon Gas to Plasma using thermionic electron emission and expelling the Xenon Plasma from the ORU [Orbital Replaceable Unit]. Each PCU holds enough Xenon to operate for two years minimum. The PCU contains the PCU Electronics Unit and Gas Feed System as major subassemblies. 2, record 5, English, - plasma%20contactor%20unit

La Station jouit d'une protection supplémentaire grâce au «neutraliseur de plasma» qui joue le rôle de «prise de terre». En orbite, la station interagira régulièrement avec les plasmas spatiaux (particules chargées dans l'espace), ce qui pourrait entraîner la formation d'arcs électriques importants (décharges électriques significatives s'apparentant aux surtensions qui peuvent se produire dans nos maisons) entre sa surface et le milieu environnant. Ces arcs détruiraient les propriétés thermiques du revêtement extérieur de la structure, mettant ainsi en danger l'équipage et le matériel de la station. Comme son nom l'indique, le neutraliseur de plasmas neutralise les charges électriques en transformant une petite quantité de gaz en ions et en électrons, ce qui a pour effet de décharger sans danger dans l'espace les électrons excédentaires créés par la charge superficielle. 5, record 5, French, - neutraliseur%20de%20plasmas

An atomic absorption spectrophotometer measures element concentrations in solution by spraying(nebulising) the solution into a long narrow hot flame. Light from a hollow cathode lamp, containing the element to be analysed, passes above the long and narrow burner to a monochromator. The monochromator isolates ground state radiation from the hollow cathode lamp. The solution is sprayed into the fuel and air premixing chamber feeding the flame. Free atoms are produced in the flame because of the heat and reducing conditions. If the atoms are the same as the element in the lamp, then light is absorbed. The degree of absorption depends on the amount of that element present in the original solution. The results are compared with standard solutions which allow concentrations to be determined. The technique can be highly precise and accurate. 2, record 7, English, - atomic%20absorption%20spectrometer

Photoionization detector... consists of a chamber into which gases suitable for the discharge such as helium, argon, nitrogen, or hydrogen are introduced through [a] tube which serves as the cathode for the discharge. The ultraviolet radiation or glow discharge in the hollow cathode, maintained by a small current between the cathode and discharge anode, is sufficiently energetic to ionize components in the carrier gas effluent entering through the tube, the collecting electrode(anode) for the ions liberated within the chamber enclosed by the second cathode. 5, record 8, English, - photoionization%20detector

Une version commerciale de ce détecteur est apparue récemment sur le marché, il est composé d'une lampe UV [détecteur à photoionisation] scellée qui émet un rayonnement à 121,6nm (10,2 eV) à travers une fenêtre en fluorure de magnésium. Si le soluté passant dans ce détecteur a un potentiel d'ionisation inférieur à 10,2eV, il s'ionise en absorbant un photon. Les ions issus de cette photoionisation sont collectés en appliquant un potentiel positif sur une des électrodes. Le courant qui en résulte est amplifié par un électromètre identique à celui utilisé avec un détecteur à ionisation de flamme. 1, record 8, French, - d%C3%A9tecteur%20%C3%A0%20photoionisation
