Description

Известны устройства дл  измерени  быстрых изменений температуры катода электронных ламп, содержащие фотоэлектронный усилитело и подключенный к нему индикаторный блок, регистрирующий напр жение на выходе усилител , по которому суд т о температуре катода. Подобные устройства не могут быть использованы дл  измерени  температуры катодов газоразр дных приборов, так как свечение г.аза измен ет уровень напр жени  на выходе фотоэлектронного усилител , в результате чего резко снижаетс  точность измерений.Devices are known for measuring rapid changes in the temperature of the cathode of electron tubes, which contain a photoelectronic amplifier and an indicator unit connected to it, which detects the voltage at the output of the amplifier, which is used to judge the temperature of the cathode. Such devices cannot be used to measure the temperature of the cathodes of gas discharge devices, since the luminescence of a gas changes the voltage level at the output of the photoelectron amplifier, as a result of which the measurement accuracy decreases sharply.

В описываемом устройстве, с целью устранени  вли ний свечени  таза на точность измерений температуры катода, между исследуемым катодом и фотоэлектронным усилителем установлен монохроматор, поглощающий световое излучение газа в колбе газоразр дного прибора.In the described device, in order to eliminate the effects of the pelvic luminosity on the accuracy of cathode temperature measurements, a monochromator is installed between the cathode under study and the photoelectronic amplifier, which absorbs the light emitted by the gas in the discharge tube of the gas discharge device.

Световой поток от исследуемого катода 1 (см. схему) по светопроводу 2 через монохроматор 3 направл ют на фотокатод электронного умножител  4, работающего в красной и инфрокрасной област х спектра Выходную щель монохроматора 3 настраивают так, чтобы на фогокатод умножител  поступал световой поток, не содержащий спектральных составл ющих свечени  газа, наполн ющего лампу, ввиду чего это свечение не будет вли ть на точность измерени  температуры катода. Выход от электронного умножител  через усилитель 5 подключен к индикаторному прибору, например электронно-лучевому осциллографу 6- По величине сигнала на входе осциллографа суд т о температуре исследуемог1; катода.The light flux from the cathode 1 under study (see diagram) via the light guide 2 through the monochromator 3 is directed to the photocathode of an electron multiplier 4 operating in the red and infrared regions of the spectrum. The output slit of the monochromator 3 is adjusted so that the light flux not containing the spectral components of the luminescence of the gas filling the lamp, in view of which this luminescence will not affect the accuracy of measuring the temperature of the cathode. The output from the electron multiplier through the amplifier 5 is connected to an indicator device, for example, an electron-beam oscilloscope 6- The temperature of the test is judged by the magnitude of the signal at the input of the oscilloscope; the cathode.
