which stable operation requires that the grid potential fulfill certain condi- 

 tions dependent upon the frequency, wave form of the grid voltage, and 

 circuit constants. It has been found possible to operate certain standard 

 thyratrons at switching frequencies as high as several hundred kilocycles 

 per second. For these higher frequencies the deionization of the tubes is 

 incomplete but normal switching behavior is obtained.
