I am thinking of rewriting my custom source file in the new format but there are a few things that are not clear to me.
In the old format, I had full controll of e.g. the direction of the primary by setting e.g. TXFLK (NPFLKA) to a specific value. In the new source format, I have the option to change the beam divergence (divergence_x = …) which suggests that some rng will decide the direction of each primary within that divergence later on. Is it still possible to have full controll of all parameters?
I need the particle energy set in the BEAM card to calculate the beam distribution. Somehow I doubt that setting energy_logical_flag = .true. will allow me to use momentum_energy if I didn’t set it myself. Can I still access TKEFLK (NPFLKA) like before?
