Service conditions:

1. The lamp panel and fastening of thyratron in the scheme have to provide free access of air to the lower surface of a socle and to a thyratron flask.

2. Increase in anode tension to 25 kV after a warming up of the cathode has to be made within 0,5-1 min. In the course of work of thyratron in the pulse mode instant inclusions and giving of full tension of the anode are allowed.

3. At a tension on the anode higher than 20 kV thyratron creates the intensive x-ray radiation demanding protection.

4. The loading resistance mismatch (about 5%) with a wave resistance of the line is necessary for creation on thyratron of negative tension after passing of an impulse of current.
