Re: Question BeamOn won't allow generating more than 3 billion events (John McFee)

Hi,

Does your individual event have to have single primary particle?
If you shoot three primary particles per event, you need only one 
billion events to loop. Otherwise, please make multiple runs and
merge their results.

Hope this helps,
Makoto
