CV41 magnetron
 |
This valve measures 245x114x68mm overall. |
This magnetron has the serial number 10134 and might be a type 'B' but it is unclear.
The CV41 was developed in 1941 and used in early production models of the GL3 radar. It was the last unstrapped S-band magnetron to be developed in the UK and was replaced in 1942 with the echelon strapped CV120.
| Heater voltage | 6.0V |

| Wavelength * | 10.70 ±0.2 cm |
| Typical operating conditions ** | |
| Peak anode voltage | 25kV |
| Peak anode current | 40A |

*: there are three frequency variants: A has a wavelength of 10.56, B is 10.70 and C is 10.84 cm, all ±0.07cm.
**: These operating conditions refer to a sensibly square pulse shape, 1µs duration, repetition rate 500 cycles per second max, and during operating and testing air must be blown through a fitting surrounding the fins. In no case shall the temperature of the anode exceed 140°C.
