Re: Streamer Length Calculations

Hi Finn,

The range is a manufacturing tolerance. The full 900V gap fires repeatable to like 0.1%. I imagine temperature does affect that though. The SIDACs do tend to be very close to the 300V number though as far as firing voltage.

So they fire very close to 300V and they always fire at the same given voltage. I can sneak the voltage up to a volt or two below the Vbo with no problem repeatably. I remember one section fires at 927 volts but I have not really paid any attention to the variation of Vbo.

Since you state that the sisg circuit is super repeatable, I look at the datasheet,
and wonder why the Vbo of the devices is only promised to fall within a range of 60 volts (270V-330V for the 300V types ).

What is your experience with regard to firing voltage, is it alwas spot on the rated center voltage (300V), and does it ever vary, (apparently not?)

Cheers, Finn Hammer

Hi All,


The SISG is wonderful since it eliminates so many variables as is perfectly repeatable!! I still need more data from "BIG" SISG systems like I am working on now to solidify the constants... It is sort of cool that we know so much about "lossy" coils that all the rest will just work out when their losses are added into the mess... I am "hoping" the DRSSTC portion will just work out happily too... The DRSSTCs lack of "fixed bang energy" made them "messy" to do these studies with...
