Dear Oscar
You have to give your RESNUCLE detectors different names if you want to
associate them with different cooling times. Otherwise, how should FLUKA
know which detector should be associated, e.g., to cooling time index 1
DCYSCORE 1. air air 1.RESNUCLE
if all four RESNUCLE detectors are called 'air'?
Cheers
Stefan
