Re: Beta- atmosphere and the Cavity Magnetron

Immediately one thinks along these lines it becomes bloody obvious what the real secret of the cavity magnetron is. Do you remember the water based vacuum pumps one used in chemistry class - the ones where a constrained jet of water passes though and sucks air out of the connected vacuum apparatus.   Obvious  Frank has been examining his wife's perfume atomizer <grin>. Actually one needs to look no further than the pipe organ at church. Should one have an inclination toward the mischevious,  one could " re-arrange" the pipes to produce the correct resonance to shatter the faux pax diamond broache worn by Mz Fine. sitting on the 18th pew. Frank mentions an analogy to the pressure that " develops" inside the cavity. A pipe organ fits that analogy. On the subject  of socalled " absolute" vacuum. Absolute vacuum is easily demonstrated by the use of a differential pressure gauge disregarding hysteresis. Richard
