Dear Zhefu,
According to the manual:
For heavy ions, use the name HEAVYION and specify further the ion
properties by means of option HI-PROPErt. In this case WHAT(1)
will mean the energy (or momentum) PER NUCLEAR MASS UNIT, and not
the total energy or momentum.
In your input you are using total energy (5.16 GeV) instead of energy per nuclear mass unit (0.43 GeV).
Best regards,

Objet : [fluka-discuss]: Quesion about bragger peak of heavyion transport
Dear all,
I want to calculate the bragger peak of carbon ion transport in water.
I know the bragger peak is 31.3cm in water with 430MeV/u carbon ion.
but when i caculate with Fluka , the result are shown below.
The result seems wrong and I don't know what's wrong with my caculation.
Here is my calculation condition in detail:
The energy of carbon ion equals to 0.43*12 GeV=5.16GeV.
I have linked ldpmqmd and recompile the fluka execuation.
Here is the bragger curve when i ran 10cycles with 1e3 primary histories:

I have attatched my input in the attatchement.
Any help will be appreciate and thanks in advance.
Zhefu
