High-power forced-air-cooled screened grid triode, mainly intended as pulse modulator switch for power up to 2 MW. Either grid is made of metal rods mounted in recessed grooves inside the anode block or the oxide is selectively removed from the cathode surface behind the grid rods. In both arrangements high-speed electrons do not hit the grid. In this way low grid currents are possible even at very high anode currents and secondary emission from the grid is prevented.

  • 45 kV plate voltage, 50 kV peak
  • 90 A pulse current, 200 A peak for the first 0.1 us
  • 3 kW plate dissipation
  • 10 min warm-up time
