Tremolo controls

[Palmer, Ralph]

Greetings -

In the following construction, I can't figure out what controls what.
Can someone please try to explain to me how the calculations are made?
The construction, as written, (in 4/4 time) produces a tremolo between
c-sharp and e, with the c-sharp and e appearing as half-notes. It seems
the "32" produces the 3 beams, but how does the "8" produce the
appearance of a half-note? Or am I looking at it the wrong way?

\repeat "tremolo" 8 { cs''32( e''32) }

Thank you for any help you can give me,

Ralph
