State of development of magnetron IOS"F 2 on JuITT 134_3,,
a) it the end of June the first two models were received. ';. change had been
made in the original plans. According to the second specification 10 - - 4,
the cone of the anode :per;>nents was to have at the top a diameter of 2 rmi
and the cone was to have an incline of 70 301. In the experimental models
the diameter at the top was 1.8 mm. and the incline 2?. `1'he total hei rYht
of the cone was reduced from 6 to 5 rim. The purpose of this change was- to
decrease the capacity of the opposite anode seen.t in order to create more
favorable conditions for the excitation of the shorter waves.
b) In both tubes a long disturbing wave (Storrrelle) was noti^ewe at a wave
length of approximately /4 - 5 cm. 1 t one of the tubes there was another such
wave at 2.4 dmQ wave length which, however, was very weak. This was the
harmonic, wave of a fundamental oscillation at 4.8 cm. wave length. It was
not possible to receive a shorter wave vri.th these two exoeririental_ models.
This was apparently for two reasons. 1) To obtain a short wove the anode
voltage must he about 1800 volts. The anode voltage could, however, be
raised only to about 800 volts, since at a higher anode )ltage the intens i ty
of the long disturbing waves was so great and the positive ion bombardment
of the filament became so strong that the heating filaments risked be:ingr
destroyed. 2) On opening the tubes it was observed that the inside of the
ceramic ;)art had been covered so extensively with copper vapors that no
energy- could radiate into the connected circuit system. New models are
now he.L.n; produced, in which the anode section has two built-in screen parts
to prevent formation of the long disturbing wwve. Especial attention is given
to the technological preliminary treatment and the pump process, in order
to prevent a nett gas; in " of the ceramic 'arts.
