| 41. | The brothers and Hansen ultimately created the klystron, the first tube that could generate electromagnetic waves at microwave frequencies.
|
| 42. | Lovell continued his work on the production antenna design using klystrons, and wrapped up this work on 22 July.
|
| 43. | They typically can amplify across a broad spectrum of frequencies; however, they are usually not as tunable as klystrons.
|
| 44. | Klystron tube technologies for very high-power applications, such as synchrotrons and radar systems, have since been developed.
|
| 45. | There are often several regions of reflector voltage where the reflex klystron will oscillate; these are referred to as modes.
|
| 46. | Without this information, the klystron would not be tunable properly, and hence not perform well, if at all.
|
| 47. | The technician must be careful not to exceed the limits of the graduations, or damages to the klystron can result.
|
| 48. | Moreover, to some extent, the klystron work at Birmingham had continued because of the Army's GL efforts.
|
| 49. | As he garnered patents by the score, he invented a reflex klystron, a type of vacuum tube used in radar.
|
| 50. | Some tubes, such as magnetrons, traveling-wave tubes, carcinotrons, and klystrons, combine magnetic and electrostatic effects.
