TIME JITTER IN ROTARY-GAP TESLA COILS

 Submission for Jim Sheppard; (c) 1991 Robert M. Jamison                         TIME JITTER IN ROTARY-GAP TESLA COILS                       -------------------------------------                                   ABSTRACT    The source of time jitter in rotary gap Tesla Coils is examined both  experimentally and mathematically.  Calculations demonstrate that jitter  appears even if the rotary gap is machined to high precision.  The  principal source of jitter is shown to be the ringing of the capacitance  and transformer inductance in relationship to the rotary electrodes.  A  computer model of jitter was made and supplements the text.                                      -*-    The tone of a rotary gap is the simplest and most immediate indicator of  the presence of jitter.  A gap with little jitter has a musical tone and  illuminates with a steady glow much like a natural gas pilot light.  As  the jitter increases, the tone takes on a nervous quality and the gap  illumination flutter

FUNHOUSE! The cyberzine of degenerate pop culture

FUNHOUSE! is dedicated to whatever happens to be on my mind at the time I'm writing.  The focus will tend to be on those aspects of our fun-filled world which aren't given the attention of the bland traditional media, or which have been woefully misinterpreted or misdiagnosed by the same. FUNHOUSE! is basically a happy place, and thus the only real criteria I will try to meet is to refrain from rants, personal attacks, and flames - and thus FUNHOUSE! is an apolitical place.  Offbeat films, music, literature, and experiences are largely covered, with the one stipulation that articles are attempted to be detailed and well documemnted, although this is no guarantee of completene
