The thermionic vacuum tube and its applications (1920)
Van der Bijl, Hendrik Johannes, 1887- · New York McGraw-Hill Book, Co · leaf 307
ONIC VACUUM TUBE where k is a constant, we find: /iCr (l+n)2 L n{^x — n) This is a niininimn for ■m+2 (17)(18) For tubes having a high value of /i, therefore, Li should be approx-imately equal to L2. If m is low, on the other hand, the bestcondition can necessitate making Z/2 considerably smaller… … at a sufficiently high negative potential to insure that there is noappreciable convection between filament and grid, the conditionfor oscillation for this circuit can also be easily obtained. Thepotential eg applied to the grid is given by o = q\ ^dt, (19) and the electromotive force induced in…
