Description

Es ist bekannt, Röntgenröhren mit elektrischen Spannungen, die außer ihrer Richtung auch ihren Betrag in möhr oder weniger engen Grenzen beibehalten, von einer Brückenschaltung aus zu versorgen, welche in zwei einander benachbarten Brückenseiten Kondensatoren und in den beiden anderen Brückenseiten elektrische Ventile enthält. Wie bekannt, kann man in solchen Einrichtungen dieIt is known to use X-ray tubes with electrical voltages that are out of direction also maintain their amount within more or less narrow limits, from a bridge circuit from supplying which capacitors in two adjacent bridge sides and in the other two sides of the bridge contains electric valves. As known, one can use the

Ein Fortschritt ist hierin bei der neuen Einrichtung erzielt, die in einem Ausführungsbeispiel in der Abbildung, der Schaltungsanordnung nach, schematisch dargestellt ist. Wie bei den bekannten Einrichtungen der erwähnten Art befindet' sich die Röntgenröhre α in dem einen Brückenzweig, während in zwei einander benachbarte, je mit einem der beiden Enden des Zweiges der Röntgenröhre verbundene Brückenseiten Kondensatoren b und in die beiden übrigen Brückenseiten elektrische Ventile c, beispielsweise Hochvakuumröhren mit Glühkathode, geschaltet sind. Gemäß der Erfindung erfolgt nun die Verbindung mit der Erde d über einen oder mehrere Kondensatoren e, vorteilhaft von geringer Kapazität.A progress has been achieved here with the new device, which is shown schematically in one embodiment in the figure, according to the circuit arrangement. As with the known devices of the type mentioned, the X-ray tube α is located in one branch of the bridge, while in two adjacent bridge sides, each connected to one of the two ends of the branch of the X-ray tube, capacitors b and in the other two bridge sides electrical valves c, for example High vacuum tubes with a hot cathode, are connected. According to the invention, the connection to earth d now takes place via one or more capacitors e, advantageously of low capacitance.

Dadurch ist die Asymmetrie der Spannungsverteilung längs der Stromquelle / in bezug auf das Erdpotential, wie die Erfahrung bestätigt, auf ein unschädlich geringes Maß gebracht.Thereby the asymmetry of the voltage distribution along the current source is related on the earth potential, as experience confirms, to a harmless low level brought.
