 Sir Avanor2003-09-03 00:13:56 I've been running the Muon software for a few days now, and there's a few things I am wodering about.1) What does the t=13.27ns (3412/33217 particles) bit actually mean?  I can guess that 13.27 nanoseconds have elapsed in the current trial, but the particle ratio is a mystery to me.  I've been trying to work out a relation between this ratio and the resulting muon transfer percentage, but there seems to be only a very tenuous relationship.  Probably because my understanding of it is poor.2) I notice that someone has achieved a muon transfer of over 16%. Is this better than a 'conventional' design?3) When are there going to be new BestNNN files?  I figure that, after 250+ work units without them, I have done by bit for design variety.4) My best transfer rating is 0.825% is that good or bad for under 300WUs?Thanks!He who liketh long words. [DPC]Stephan2022003-09-03 08:32:43 Visit http://stephan202.qik.nl for a recent bestNNN file.0.8% after 300Wu's doesn't seem too bad.  There's a lot of randomness in these calculations.As for the 16%: those high yields have been created in an artificial way, by random seeding.  That is discussed in another thread on this forum.---Dutch Power Cow.MOOH!
