Srim3D.py

Srim3D.py is a Python script containing a set of functions that make it easier to work with SRIM's 3D ionization output. This output can be generated in TRIM by clicking on the "F" button next to "Ionization 3D":

Setup

To start using srim3d.py, download this file and save it in the same folder as your Python code. Then add this line to the beginning of your Python code:

import srim3d

If you want it to be available for all projects, you can also save the file in the folder containing Python libraries. On Windows with Anaconda 3 this is C:\ProgramData\Anaconda3\Lib, and on Linux with Python 3.8 this is /usr/lib/python3.8.

Usage

extractData(file="Ioniz-3D.txt")

This function takes as parameter the name and path of SRIM's 3D output file, and returns a numpy array with the data. If the parameter isn't specified, it looks for a file named Ioniz-3D.txt in the same folder as the script.

ions(data)

This function takes as parameter the numpy matrix returned by the extractData and returns a numpy vector with the deposited energy only as a function of depth (so summing up over all transverse positions at a given depth).

transverseIons(data)

This function takes as parameter the numpy matrix returned by the extractData and returns a numpy vector with the deposited energy only as a function of transverse position (so summing up over all depths at a given transverse position).
