External magnet, single-ended CW magnetron. Neutrode 3-section anode structure, the central one being connected to the mid point, the voltage node, of the internal loop. This three-electrode structure originated a new family o multi-segment magnetrons, referred to as 'tropotrons' by RCA, in which the internal section of the resonating line makes complete loops around the anode structure.
750 to 1150MHz operating frequency, depending upon the resonating lines
200 W min CW out. 1500 gauss
400 mA max at 1800V, 40% efficiency.
