Brand: Telefunken Deutschland (TFK), (Gesellschaft für drahtlose Telegraphie Telefunken mbH
Tube type:  Pulse magnetron 
Identical to LMS10 = LM521

Was used by Radar
Filament Vf 6.3 Volts / If 2 Ampere / Half indirect

This was the first multi-cavity magnetron made in Germany in WWII. It was the exact copy of the British CV64 recovered from a Sterling bomber landed near Rotterdam in the late 1943 or in the early 1944.

It was first used in the so called Rotterdam-Gerät, a 10-cm radar set very similar to the British H2S, with some differences in the local oscillator and in the TR switch. Due to the lack of cobalt, needed for the magnet, very few of these sets were made, using magnets recovered from Allied crashed planes. Later Germany developed its own airborne radar set, the Berlin, where the magnetic field to operate the LMS10 was supplied by a controlled current electro-magnet.A few LMS10 magnetrons were also used in other quasi-experimental sets, as the Korfu and the Panorama Z.

Productions until the end of the war were quite low, in the order of 1000 units, run by Telefunken, about five units per month, and by Sanitas
