Abstract : Experimental tube No. 1 was repaired and additional testing was carried out. Oscillations were observed from 94.2 to 101.3 Kmc. A calorimeter was used to check peak RF power measurements made previously with a calibrated crystal. Agreement was reasonably good and peak powers of the order of 50-100 kw were observed. An average power of 50 watts was measured at 99 Kmc. About 8 kw of average beam power was passed through the circuit before it was destroyed. A new gun is being designed that will result in more RF output power and lower magnetic focusing field. Silicon carbide waveguide loads are being tested to replace the sprayed stainless steel loads.
