Description

Лампы с ХОЛОДНЫМ катодом получили в насто щее врем  широкое распространение в различных област х техники, в том числе в специальных электронных и радиотехнических устройствах и вычислительных аппаратах.Lamps with a COLD cathode are now widely used in various fields of technology, including special electronic and radio devices and computing devices.

Наличие газового промежутка между управл ющим анодом и катодом часто вызывает самовозбуждение схем, использующих указанные лампы. Кроме того, вследствие инерционности процесса ионизации, запуск этих схем может быть осуществлен только От сравнительно продолжительных импульсов. Во избежание самовозбуждени  запускающие импульсы приходитс  подавать на управл ющий анод через малую емкость, в результате чего затрудн етс  возникновение разр да при пологом фронте запускающих импульсов.The presence of a gas gap between the control anode and the cathode often causes self-excitation of circuits using these lamps. In addition, due to the inertia of the ionization process, the launch of these schemes can be carried out only From relatively long pulses. In order to avoid self-excitation, the triggering pulses have to be supplied to the control anode through a small capacitance, as a result of which the occurrence of a discharge at a sloping front of the triggering pulses is difficult.

В описываемой схеме указанные недостатки устранены тем, что в схеме подачи запускающих импульсов применены диоды, включенные параллельно или последовательно газовому промежутку.In the described scheme, these disadvantages are eliminated by the fact that diodes connected in parallel or in series to the gas gap are used in the supply circuit of the trigger pulses.

Схема с последовательным включением диода приведена на чертеже - позици  а, с параллельным - позици  б.A circuit with a series connection of the diode is shown in the drawing - position a, with parallel - position b.

При использовании подобных схем уменьшаетс  опасность самовозбуждени . Запуск схем может производитьс  как от импульсов с пологим фронтом, так и от весьма кратковременных импульсов. Схемы (см. чертеж, позицию а) могут запускатьс  также от высокочастотных импульсов, а схемы второго варианта исполнени  (см. чертеж позицию б)- от импульсов отрицательной пол рности.Using such schemes reduces the risk of self-excitation. Triggering of circuits can be carried out both from pulses with a gentle front, and from very short pulses. The circuits (see drawing, position a) can also be triggered by high-frequency pulses, and the circuits of the second embodiment (see drawing drawing position b) can also be triggered by pulses of negative polarity.

Подача посто нных напр жений на основной и управл ющий аноды осуществл етс  обычным способом от общего источника через сопротивлени .The supply of constant voltages to the main and control anodes is carried out in the usual way from a common source through resistances.

В схеме (см. чертеж, позицию а) запускающий импульс подаетс  на управл ющий анод через диод Дь последовательно с которым включена значительна  емкость С. Дл  более надежного запуска от импульсов с крутым фронтом диод Ml и емкость Ci шунтированы малойIn the circuit (see drawing, position a), a triggering pulse is applied to the control anode through diode Db, in series with which significant capacitance C is connected. For a more reliable trigger from pulses with a steep front, diode Ml and capacitance Ci are shunted by a small
