 unterhalb derjenigen der   Röhre liegt. Da   diese Temperatur ziemlich konstant ist, schwankt der Druck in der Röhre auch im Betrieb im wesentlichen nicht. Ist ausser dem Quecksilberdampf noch ein anderes Gas, z. B. Argon, in der Röhre vorhanden, so ist der Druck dennoch von der Gasabsorption weniger abhän- 
 EMI2.1 
 dass das Quecksilber in reinem Zustande bleibt und kein-Amalgam bildet. Dies kommt der Beschaffenheit der Gasfüllung zugute. 
 EMI2.2 
 Quecksilber auf eine    bestimmte, dem gewünschtenDampfdruck entsprechende Temperatur gebracht   wird. 



  Man kann zu diesem-Zwecke ein elektrisches Heizelement-M verwenden und dessen   Stromstärke   gegebenenfalls   selbsttätig-derart regeln.-dass   die Temperatur des Quecksilbers und dementsprechend der Druck in der Röhre einen beliebigen konstanten Wert hat. Selbstverständlich ist es nicht beabsichtigt, das Quecksilber auf eine höhere Temperatur als diejenige in der Röhre zu bringen. Es können natürlich auch andere Heizmittel, gegebenenfalls sogar ein Kühlmittel, verwendet werden, um der Temperatur des Quecksilbers einen beliebigen Wert zu geben. 



   Vermöge der Befestigung des Quecksilberbehälters im Füsschen der Röhre wird die Gefahr eines Abbrechens desselben beseitigt und an Raum gespart. 
 EMI2.3 
 in einem von dem Kathodenraum durch eine Scheidewand getrennten Raum befindet, welcher sich zwischen der Glühkathode und der unteren Begrenzung des vom Entladungsgefäss umfassten Raumes erstreckt.

 below that of the tube. Since this temperature is fairly constant, the pressure in the tube does not fluctuate substantially even during operation. Is there another gas besides the mercury vapor, e.g. B. argon, is present in the tube, the pressure is still less dependent on the gas absorption.
 EMI2.1
 that the mercury remains in a pure state and does not form an amalgam. This benefits the nature of the gas filling.
 EMI2.2
 Mercury is brought to a certain temperature corresponding to the desired vapor pressure.



  An electrical heating element-M can be used for this purpose and its current intensity can be regulated automatically, if necessary, in such a way that the temperature of the mercury and, accordingly, the pressure in the tube have any constant value. Of course, it is not intended to bring the mercury to a higher temperature than that in the tube. It is of course also possible to use other heating means, possibly even a coolant, in order to give the temperature of the mercury any desired value.



   By fastening the mercury container in the base of the tube, the risk of the tube breaking off is eliminated and space is saved.
 EMI2.3
 located in a space separated from the cathode space by a partition, which extends between the hot cathode and the lower boundary of the space enclosed by the discharge vessel.
