Hello, I have looked at Question about 150MeV electron in Aluminum CSDA range. I followed the rules to get the range of 1 MeV electrons in the tungsten target. I got a range around 0.02 cm, while in ESTAR, it should be around 0.04 cm. I am not sure where the problem is. I attached my Flair, and the range (1-D graph lin-lin and semi-log). Please advise.

Update: I think I figured out the problem. I calculated the total track length inside the target, I got 0.0403 cm which is very close to ESTAR. The ESTAR calculates the range as continuous enegy loss occurs in str. line motion with no scattering, however FLUKA calculates the real range taking into account the scattering, which makes considerable difference in the low energy beam (several MeV and lower). Please correct me of I am wrong.
