NOTES

1. With no anode input power.
  On the application of anode power, the heater voltage must be reduced as follows:

  where Pi = mean input power in watts.
  The magnetron heater must be protected against arcing by the use of a minimum capacitance of 4000 pF

  shunted across the heater directly at the input terminals; in some cases a capacitance as high as 2 mF

  may be necessary depending on the equipment design. For further details see the Magnetron Preamble.

 

2. The anode temperature must be kept below the limit specified by means of a suitable flow of air over

  the anode body.
