Dear Núria
Related to your question, note that there are two ways to sample from a SR spectrum as explained in the FLUKA FAQ (
http://www.fluka.org/fluka.php?id=faq&sub=4). Independently of the method you are using, I recommend to test your routine using a simplified geometry (vacuum and blackhole scoring USRBDX or USRTRACK) to ensure that you properly sample your source spectrum.
For the normalization, what you are suggesting is correct. The fact that some bins "contribute" more than others is accounted for in the sampling (if you sample each bin with the same probability then the weight of the primary has to be adjusted while if you sample according to the bin content then bins with a "higher" contribution will be sampled more often....). It highlights the importance of checking the consistency of your source routine....
Greetings

Subject: [fluka-discuss]: How can I obtain the dose rate (pSv/s)?
Dear Fluka experts,
I'm simulating a source of photons with a certain energy spectrum.
Each bin of energy has a certain probability. I'm scoring the dose equivalent but I would like to obtain the dose rate, how can I obtain that?
I attach the spectrum of the source:energy, flux (photons/s) and probability of each bin.
If I obtain for example a dose of 0.0001 pSv (per incident particle), how can I make the convertion to dose rate? Is it correct if I simply multiply the dose (pSv/particle) x total flux (partciles/s)? We have to take into account that some bins contibute more than others to this dose.
Thank you very much.
Núria
