How to Calculate Electronic Damage?

   Hi I am trying calculate electronic damage when 20 Mev (or greater )
electron beam hits a sample target (Silicon).

    I carefully red the article and tried to implement it myself.

Now I have couple of SIMPLE questions regarding to that

As I understood in order to calculate damages I should do following steps
       1) Do calculation USERBIN and USERTRACK cards with part. type
Dose/, //SI1MEVNE/and //HADGT20M//
       2) Take values from plots of that cards
       3)Compare plots values with the chart that I attached( See
Attached Image)

I ask experts If you have time can you take a look to my input card and
say what I may miss?

Many Thanks!
