We are searching for ten pieces of a particular radar component Traveling Tube Wave (TWT), otherwise known as an electron tube, with the following National Item Identification Number:
NSN # 5960-01-027-6954
Through various manufacturers in the past, several reference numbers (part numbers) have been assigned to this product. Here are the three most widely utilized ones in the past:
#L5416-54 (L-3 Communications Corporation) #VTL-5341H3 (Communications & Power Industries Incorporated) #138C660H01 (Northrop Grumman Systems Corporation)
Item Description: An inclosure, including two or more electrodes, in which a flow of electrons may occur through a vacuum or a contained gas. The electronic conduction takes place either by means of electrons emitted from a cathode or by ionization of the contained gas. Includes phototubes (photoemissive type only), Geiger-Mueller tubes, traveling wave tubes, cathode ray tubes, and microwave tubes (Klystron, magnetron, or the like). Excludes items whose primary purpose is to produce light energy. Also excludes PHOTOELECTRIC CELL; and SEMICONDUCTOR DEVICE.
Item Specifications (Technological Details):
- L-band Ring Loop TWT - 1.24-1.36 GHz - 6 kW peak power output - Pulse width 40 µsec @ duty .032 - Peak cathode voltage 11 kV @ 2.2 A - Heater 19 volts @ 2.8 amps - Grid pulsed 275 volts; current 300 mA - Grid bias- 50 volts; current @ 50 mA - Collector voltage 0 kV (to ground) - Grid pulse voltage 228 volts - Body current 600 mA - 52 dB saturated gain - Weight 22 lb
Item Benefits: Long operating life; forced air cooling.
Here are the names of past manufacturers: Northrop Grumman Systems Corporation, L-3 Communications Corporation, Communications & Power Industries Incorporated. If you have any sort of familiarity with this product, we would be happy to conduct business with your association. Or if you are affiliated with any other company that would specialize in the knowledge of this field, please let us know. Are there newly developed NSN numbers for this part?
