Reasonable input parameters for validation testing

[grzanka]

We would like to write down values of crucial input parameters for this method:

def ks_initial_IonTracks(E_MeV_u,
                         voltage_V,
                         electrode_gap_cm=0.2,
                         particle="proton",
                         RDD_model="Geiss",
                         grid_size_um=3.0,
                         a0_nm=8.0,
                         use_beta=False,
                         PRINT_parameters=False,
                         SHOW_PLOT=False,
                         theta_rad=0):

These should be used for validation of new, faster parallel implementation

• E_MeV_u : 10 ... 250 : lower energy, longer computation time
• voltage_V: 50 ... 300 : higher voltage, longer computation time
• particle : protons, helium, carbon, oxygen :
• grid_size_um : 1 .. 10 : lower grid size, longer computational time
