r,o Eriali Sahuettl?effel in Department TEA of Funkwerlc l~oepenick, which urea
tested at Rheinsberg in early March 1954, operated satiafaatvri]y with an out-
put Qf between 4a5 and le? kilowatts. H?wever, at a higher output, purrent
amplifications of up to 30 amperes occurred at various points on the,aircuit;
As a result, power losses through increase of temperatua.^e prevented the device
from .reaching its intended output of two kilowatts.
Schuettloeffel is ncnr trying to correct the fault by emending the drosa-
aection of the conducting tubes in order to diminish the current density.
