Dear experts
I would like to find out something on FLUKA, which may be a little vague for me in manual.
Could you help me with the following, please ?
1.What's the meaningful of the ALL-Nucleon spectrum existing ? When do I use it?
2.In SPECSOUR/GCR-ION, why choose the WHAT(12)< 0, i.e.make the ions are split instead of treating them as real one?
3.How does the spectral index for sampling work? why set 1.75 is approprite? (SPECSOUR/GCR-ION WHAT(5))
Does the transition energy for sampling has recommended value ? What should I set it according to? (SPECSOUR/GCR-ION WHAT(6))
What's the number of the energy point in the spectra refer to? If I increase it value, what benefit will happen?
(SPECSOUR/GCR-ION WHAT(9))
4.What's the meaning of the possibilities used for the various ions? (SPECSOUR/GCR-ION WHAT(11))
If I use zzphi0465.spc of 28 files totally and set 5000 primary/cycle, how the sampling work and what'the distributon of the
sampling results? Is the component percent of sampling results same as the real CR?
5.There is a DPMJET card in flair, is it equivalent to the ldpm2rqmd or can only use it above 5 Gev?
And does the limit of 1000/n mean 1000/nucleon? what's the max value I can put in SPECSOUR/GCR-ION WHAT(4)?
Please take it easy, any one of them being answered would help me a lot.
Thank you and best,
Yi
