Platinotron MU-11A-1
Water-cooled • Refroidi par eau • Wassergekühlt

The Platinotron (from Greek "platino" = make wider, expand, and "electron") is a radial M-type backward wave tube used in radars, in medicine (radiation therapy of oncological diseases), and in equipment for non-destructive testing. It is most commonly used as an amplifier and referred to as an amplitron. When supplied with additional devices for generation of positive feedback and operating as a generator, it is called a stabilotron. Desirable characteristics of the platinotron include: efficiencies of 50 to 70 per cent; high peak and average rf power outputs, electronic bandwidths of 10 per cent with nearly constant efficiency over the entire bandwidth, low-phase pushing figure, low operating voltage, nominal gain of 10 db over a ten per cent frequency range, and a simple, compact mechanical structure.
