| 31. | The best known result of this research was the klystron tube invented 1937 by Russell and Sigurd Varian.
|
| 32. | In the klystron, a beam of electrons was passed through a metal disk known as a resonator.
|
| 33. | After trying a variety of designs based on klystrons and older-style magnetrons, they eventually gave up.
|
| 34. | The klystron became an important component in radar-detection and guidance systems and later in electron-acceleration technology.
|
| 35. | Some modern klystrons include depressed collectors, which recover energy from the beam before collecting the electrons, increasing efficiency.
|
| 36. | The only amplification devices suitable for pulse-Doppler are klystron, traveling wave tube, and solid state devices.
|
| 37. | Klystron 9 has the ability to see storms other radars can't see and see deeper into those storms.
|
| 38. | High voltage DC on a cylindrical anode accelerates the modulated electron beam through a small drift tube like a klystron.
|
| 39. | First, the klystron uses " velocity modulation " to create bunching; its beam current is constant.
|
| 40. | Sources like the klystron and magnetron replaced the B-K tube around World War 2 and it became obsolete.
