発生することもある。In the circuit of the prior art shown in FIG. 3, the potential difference between the electrodes when a high voltage is applied is 43.8 KV between the second grid 2 and the third grid 3, 60 KV between the fourth grid 4 and the fifth grid 5, and And 4 between the third grid 3 and the fourth grid 4
3.8KV. The tri-potential electron gun supplies the voltage of the third grid 3 from the split terminal of the split resistor 9 in order to reduce the potential difference between the third grid 3 and the second grid 2 to increase the breakdown voltage in the working state. . Therefore, since the voltage from the divided terminal of the dividing resistor 9 is applied even at the time of knocking, the second grid 2
The knocking voltage between the first grid 3 and the third grid 3 is as low as 43.8 KV, which is not a value that can provide a sufficient knocking effect. The output voltage of the high voltage generator 14 is increased and applied to the anode terminal 12.
If the knocking voltage is set to be higher than 60 KV, the potential difference between the fourth grid 4 and the fifth grid 5 becomes too large, causing excessive knocking, which causes a problem. In addition, since a large potential difference occurs between the fourth grid 4 and the divided resistor 9, a portion of the divided resistor 9 near the fourth grid 4 causes dielectric breakdown. In addition, at the time of knocking, since the fourth grid 4 and the second grid 2 are connected, knocking between the lead wires of these electrodes does not take place and remains.
Similarly, knocking is performed between the lead wire of the fourth grid 4 and the low voltage side lead-out terminal 10 of the dividing resistor 9, between the lead wire of the fourth grid 4 and the heater 7, and between the lead wire of the fourth grid 4 and the cathode 8. Will not be left. As a result, discharge may occur during operation.
