Oscillator Capacitance Measurements


By R. L.


Anderson


Experiment done by R. L. Anderson and J. Riedel


Introduction


Capacity of the oscillator plate to ground was requested by Mr. Pote', electrical en- -
gineer at Harvard University. It was also desirable to have this information for comparison
with model measurements and for the records.


Experimental Setup:


The oscillator housing was separated from the transmission line housing, and the
"ii~k.
Soscillator plate coupling'loop was disconnected at its grounded end. The water lines run-
.. ning through the loop were disconnected at their entrance into the loop. The G-R imped-
ance bridge leads were connected to the 9C21 tube water jacket and to the oscillator
.housing. For accuracy an oscilloscope was used in balancing the bridge. (Oscillator wiring
diagram, Dwg.#2L2754)

.'* .
*. Results:

The plate to ground capacity with coupling loop disconnected was 113/ppf. The plate to
: ground capacity with coupling loop disconnected and two 50//ppf vacuum capacitors added
. -as in normal run condition was 219gpf. The grid circuit contains 15 50ppf vacuum
capacitors in parallel (calculated) 750/ f. The filament circuit contains 10 50/ppf
. vacuum capacitors in parallel (calculated) 500S f. It was not deemed necessary to meas-
ure the grid or filament circuits. The measurements were made with G-R Impedance
Bridge, Type 650-A Serial #1977, and are + 2ufuf. Lead capacity of 29 A! f has already
Been deducted.
