Alpha simulate in Garfield++

Garfield++ can simulate the ionization of fast charged particles in gas
Can Garfiled++ simulate the ionization of alpha and the avalanche of electrons produced by the ionization of alpha , can TrackHeed class do this? or which class I should use?

By the way,What is the difference between Heed and Srim

To simulate the ionisation by α particles you can use TrackSrim or TrackTrim. You can find examples in the folder https://gitlab.cern.ch/garfield/garfieldpp/-/blob/master/Examples/Srim/

Heed simulates the energy loss and ionisation by fast charged particles but its model is not applicable to heavily-ionising particles slowing down in the gas.

Thank you very much. In addition, I also want to know if I can get the electron information(such as the position and energy information ) generated by the ionization of alpha particles(using SRIM) because I want to simulate the avalanche of these electrons.

You can do something similar as in this example:

Thanks! I will try
