THOMSON-CSF CV6124 = CMA1232 = VX9239 Water-cooled M-Type Carcinotron
Backward Wave Oscillator
Tube à ondes régressives
Rückwärtswellenröhre

UK Military.
Frequency range: 0.66 .. 0.86 GHz.
Output: minimum 250 W.

An M-type carcinotron, or M-type backward wave oscillator, is a voltage-controlled non-resonant extrapolation of magnetron interaction. It is tunable over a wide range of frequencies by varying the accelerating voltage.

It seems likely that the CV6124 found use in a British L-Band jammer.
