Abstract

1528155 Travelling-wave tubes ENGLISH ELECTRIC VALVE CO Ltd 17 Dec 1975 [8 March 1975] 9908/75 Addition to 1451956 Heading H1D The fundamental coupled-cavity travelling- wave tube disclosed in the parent Specification is modified by the incorporation in the ferromagnetic members 1 of the clover-leaf slow-wave structure of copper inserts 5, to aid cooling. The inserts are preferably brazed between the ferromagnetic members 1 and 2, as shown.
