| 21. | An alliance was made between NTRI and JRC for further magnetron development.
|
| 22. | Their pulsed system used a new Philips magnetron with better frequency stability.
|
| 23. | The British need to produce the magnetron in large quantities was great.
|
| 24. | IV would not reveal the secret of the magnetron to the Germans.
|
| 25. | VII and a new 50 kW magnetron to produce the AI Mk.
|
| 26. | This was eventually mated with a new 200 kW magnetron.
|
| 27. | Metallic quasicrystalline coatings can be applied by plasma-coating or magnetron sputtering.
|
| 28. | During World War II, the magnetron tube technology was applied to radar.
|
| 29. | The first operational magnetrons were delivered in August 1941.
|
| 30. | The cavity magnetron was also of interest to Yagi.
