Dear FLUKA experts,
I’d like to score both LETd and LETt of primary protons in water.
I tried to use GETLET routine in fluscw.f and comscw.f.
And the results seem incorrect and they highly depend on the proton beam shape. (In principle they should not.)
My procedures are:
- define 4 USRBINs to score LETd (dose, 21bin), dose (22 bin), LETt (fluence, 23 bin), fluence (24 bin)
- use USERWEIG to link fluscw.f and comscw.f
- in both fluscw.f and comscw.f, I set (JTRACK.EQ.1 .AND. LTRACK.EQ.1) to score only primary protons and use GETLET function, else FLUSCW or COMSCW will be ZERZER
- link 21bin to comscw.f and link 23bin to fluscw
- when the simulations are done, the final voxel by voxel LETd should be (21 bin)/(22 bin), and LETt should be (23 bin)/(24 bin).
I’m not sure whether my understanding is correct.
I have attached the inp and two .f files.
And one more question, for the ENDLET and BEGLET, which one should I use in my case?
Thank you very much!
