← ScienceWhich outcome results when high anode current causes sputtering in a hydrogen thyratron?
A)Decreased grid control effectiveness✓
B)Increased hydrogen gas pressure
C)Premature cathode heater failure
D)Amplified inverse electron current
💡 Explanation
Decreased grid control arises because secondary emission disrupts gas discharge. Sputtering releases electrode material which neutralizes the grid's negative bias, weakening the 'Deionization' mechanism. Therefore, grid control is diminished rather than improving other parameters like gas pressure.
