FIELD OF THE INVENTION This invention relates to a gas discharge technique, namely gas filled dischargers.

According to the main auto 1 No. 713506 from the walls, a controlled gas-filled discharge containing an anode, a cathode and a control electrode between them, the output of which is placed inside a dielectric sleeve located in the hole of the cathode, and which, in order to expand the range of working voltages, between the control The electrode and its output have a larger gap (1).

The disadvantage of this device is the relatively large ignition delay time and the large amplitude of the control voltage required for reliable operation.

The purpose of the invention is to increase the response stability over a wide range of control voltages and to reduce the response delay time.

The goal is achieved in that in a controlled gas filled discharge containing an anode, a cathode and a control electrode between them, the input of which is placed inside the dielectric sleeve of the cathode, and a gap is made between the control electrode and its output, the dielectric sleeve is made at least , with one radial groove at the end adjacent to the control electrode.

Figure 1 shows a controllable gas-filled discharger, frontal raerez; figure 2 is a section aa in figure 1.

The sparger contains an anode 1, a control electrode 2 with a terminal 3, which is separated by an insulating sleeve 4 from the cathode 5. At the end of the dielectric sleeve 4 in contact with the control electrode 2, several grooves are made 6. Terminal 3

The claims CONTROLLED GAS-FILLED DISCHARGE by ed. ev, N 713506. characterized in that, in order to increase the reliability of operation in a wide diastroy with a gap of 7 in relation to the control electrode 2., The slug works as follows. A constant voltage is applied between the anode 1 and the cathode 5. When a high-voltage pulse of the control voltage is applied to terminal 3 of the control electrode 2, the gap 7 is alternately broken between the control electrode 2 and its terminal 3 and auxiliary spaces, the control electrode 2 is the cathode 5, the control electrode 2 is the anode 1, which entails a breakdown of the main gap anode 1 - cathode 5. In the breakdown of the gap, the control electrode 2 - terminal 3 of the control electrode creates a spark discharge in it. Under the action of the polo anode 1 - cathode 5, directional diffusion of the charged particles from this discharge occurs through the grooves 6 into the main gap and into the gap, cathode 5 is the control electrode 2. Diffusion of charged particles and discharge radiation promotes accumulation charges in the gap, cathode 5 is the control electrode 2v, which reduces the ignition delay time and the necessary value of the control voltage. It has been experimentally established that ceteris paribus, the value of the control voltage is reduced by 1.21.4 times, and the ignition delay time is reduced to half. The use of the invention will enable the design of high-speed relaxation generators. The use of the proposed discharge device as a protective device for expensive electronic products increases the reliability of the equipment. 56) Copyright certificate of the USSR N5 713506. cl.
