Dear Pan Liu,
first: p/cmq means particles/cm2. If you required neutrons in the scoring,
you will get the neutron fluence.
Second: if you are scoring the neutron fluence rate for the prompt
radiation, the normalization is done "per primary particle" and you have then
to multiply by the intensity of your source to get n/cm2*s.
You will directly get results in particles/cm2*s only if you are calculating
the residual radiation at a certain decay time (this means that you activated
radioactive decays via RADDECAY, you have defined an irradiation profile via
IRRPROFI, you have specified cooling times via DCYTIMES and you used DCYSCORE
to associate them to the USRTRACK estimator).
Best regards,
Anna
