Description
Zählrohrgerät mit mehreren Zählrohren zum Umwandeln von unsichtbaren Strahlen in sichtbare Bilder Es ist bekannt, unsichtbare Strahlen, insbesondere infrarote Strahlen, mit Hilfe von Glimmlampen in sichtbare Glimmlichtbilder umzuwandeln; z. B. ist es möglich, bei Nebel nebelfreie Bilder unmittelbar zu betrachten. Dabei wird die Helligkeit der Glimmlampe durch ein Widerstandselement gesteuert, dessen Wert sich mit der Menge der auffallenden unsichtbaren Strahlen ändert. Bei der vorliegenden Erfindung werden solche Bilder mit einer größeren Empfindlichkeit als bei den bekannten Einrichtungen dadurch erzielt, daß zur Steuerung der Helligkeit der Glimmlampe Zählrohre verwendet werden. Das wird dadurch erreicht, daß in dem Zählrohrgerät mehrere Zählrohre vereinigt sind und daß jedes Zählrohr mit einer zur Verstärkung der Impulse dienenden gittergesteuerten Gasentladungsröhre baulich vereinigt ist und sich in größerem Abstand von der Spannungsquelle und den übrigen Schaltungselementen befindet. Counter tube device with several counter tubes to convert invisible ones Radiate into visible images It is known to use invisible rays, especially infrared rays To convert rays into visible glow-light images with the help of glow lamps; z. B. It is possible to view fog-free images immediately in fog. Included the brightness of the glow lamp is controlled by a resistance element, its Value changes with the amount of invisible rays that strike. With the present According to the invention, such images are more sensitive than the known ones Facilities achieved by counting tubes to control the brightness of the glow lamp be used. This is achieved in that several counter tubes in the counter tube device are combined and that each counter tube is used to amplify the pulses Grid-controlled gas discharge tube is structurally united and is larger Distance from the voltage source and the other circuit elements is located.
Man kann die schwachen Entladungen eines gewöhnlichen Zählrohres durch eine Gasentladungsröhre mit drei Elektroden in einer Stufe so verstärken, daß ein Telefon, Relais oder Zählwerk damit betrieben werden kann. Statt einer Gasentladungsröhre mit Gitter können zwei hintereinandergeschaltete Röhren mit je zwei Elektroden verwendet werden, wobei deren Verbindungspunkt als Gitter dient. Zählrohr und Gasentladungsröhre können, eventuell mit Kopplungskondensator und Ableitungswiderstand, zu einer elektrisch abgeschirmten zylindrischen Einheit kombiniert werden, wobei die Abmessungen des Zählrohres kaum über schritten werden. So kann eine größere Anzahl von Zählrohren aus einer entfernt aufgestellten Spannungsquelle gemeinsam betrieben werden, ohne daß eine gegenseitige Beeinflussung der verschiedenen Zählrohre vorkommt. Läßt man jedes Zählrohr auf ein entfernt aufgestelltes Relais wirken, so kann mit jedem dieser Relais eine sichtbar angebrachte Glimmlampe geschaltet werden, so daß jeder von einem Zählrohr kommende Impuls die zugeordnete Lampe aufleuchten läßt. One can see the weak discharges of an ordinary counter tube amplify by a gas discharge tube with three electrodes in one stage, that a telephone, relay or counter can be operated with it. Instead of a gas discharge tube With a grid, two tubes connected in series with two electrodes each can be used with their connection point serving as a grid. Counter tube and gas discharge tube can, possibly with coupling capacitor and leakage resistance, to one electrical shielded cylindrical unit, taking the dimensions of the Counter tube can hardly be exceeded. So can a larger number of counting tubes can be operated jointly from a remote voltage source without that there is a mutual influence of the various counter tubes. One lets Each counter tube acts on a remote relay, so can each of these Relay a visibly attached glow lamp can be switched so that each of impulse coming from a counter tube lights up the associated lamp.
Gemäß der Erfindung ordnet man nun die einzelnen Zählrohreinheiten in Gestalt eines Tableans, das rund oder sechseckig sein kann, an, und jedes Zählrohr ist über die Gasentladungsröhre mit einer korrespondierenden Glimmlampe eines entfernt angebrachten Tableaus von Glimmlampen verbunden, das als Leuchtschirm für die auf die Zählrohre wirkende Strahlung dient. Dieser Leuchtschirm hat eine bisher unerreichte Empfindlichkeit, der für Röntgen- und Gammastrahlen, aber auch für kosmische Strahlen benutzt werden kann. Die Zählrohre können in diesem System in einen gemeinsamen Vakuumraum gesetzt werden. Die Strahlenmengen von Röntgenstrahlen usw., die bei diesem System angezeigt werden können, sind so niedrig, daß Schutzmaßnahmen durch Bleiwände überhaupt nicht nötig sind, auch wenn man das die Lampen enthaltende Tableau in dem strahlenerfüllten Raum aufstellt. According to the invention, the individual counter tube units are now arranged in the form of a tablean, which can be round or hexagonal, and each counter tube one removed over the gas discharge tube with a corresponding glow lamp attached panels of glow lamps connected to act as a fluorescent screen for the on the radiation acting on the counter tubes is used. This fluorescent screen has an unprecedented level Sensitivity for X-rays and gamma rays, but also for cosmic rays can be used. In this system, the counting tubes can be shared Vacuum space can be set. The amounts of rays of X-rays, etc., which are used at This system can be viewed are so low that protective measures by Lead walls are not necessary at all, even if you look at the tableau containing the lamps in the room filled with rays.
