Service conditions:

1. For thyratron ignition on a grid the positive rectangular impulse of tension has to be given.

2. For a net chain the following sizes are recommended: - resistance in a chain of the cathode of the cathodic repeater no more than 12,5 lumps, - resistance of leakage of a grid from 30 to 100 lump, - the capacity of the dividing condenser in a grid chain not less than 2000 pf.

3. Sizes of resistance of leakage of a grid and capacity of the dividing condenser are selected so that the constant of time of a chain did not exceed one third of the period of repetition of impulses.
