Yes the RC time constant (1/RC) is what you are talking about: http://micro.magnet.fsu.edu/electromag/java/timeconstant/ > It may be that what I am speaking of may involve the recharge rate of > the capacitors but it may also involve the discharge as well. There are serveral issues. The RC time constant of the charging circuit can be used to estimate the charging rate of the discharge capacitor. The minimal flash duration will depend on the speed at which the capacitor's charge can be dumped through the flash tube. In this case the flash tube's resistance in the fully ionized state is probably the limiting factor. However, it will take some time to trigger the ionization of the tube gas, and my guess is that initially the tube resistance will be pretty nonlinear. >> I'm still interested in more plus alteratives if any. OK, go to the search page associated with this mailing list: http://rmp.opusis.com/htdig/search.html and do a search on "high speed flash". - Wayde ([EMAIL PROTECTED]) -------------------------------------------------------- ISART 2003 International Symposium on Advanced Radio Technologies http://www.its.bldrdoc.gov/meetings/art/index.html -------------------------------------------------------- _______________________________________________ Cameramakers mailing list [EMAIL PROTECTED] http://rmp.opusis.com/mailman/listinfo/cameramakers
