Trim implant software
Then the SRIM approach is discussed in detail, with explicit tables showing how the values are determined. Finally, plots are included to show the difference between using Bragg's Rule additivity of stopping powers compared to the suggested corrections. Ions starting with varying Energies, Angles and Depths - TRIM can be used to calculate complex ion target interactions, such as starting the ion at some depth into the target with varying energies and angles.
These types of calculation are used, for example, for a Simulating Reactor Radiation Damage from alpha particles, b Calculating Plasma Ions hitting a solid with various energies and trajectories, c Simulating a receding surface from sputtering. All of these can be done by creating a special file which starts each ion in any location, with varying energies and trajectories.
You must use software which generates a listing of recoils from these particles, and this table can be fed into TRIM to generate the recoil cascades from each of these events. This short note indicates how this can be done. Designing "Degrader Blocks" to Lower Ion Beam Energy - With high energy beams, especially for protons, it is sometimes convenient to insert blocks of material to lower the beam energy, since this can be done quicker than re-tuning the accelerator.
SRIM can be used to accurately obtain the required dimensions to lower an incident beam to a lower energy. Please contact Johan Meersschaut at imec for access.

Simulation of excitation curves obtained around narrow resonances in nuclear reaction cross sections, within the stochastic theory of charged particle stopping, from samples of arbitrary depth composition.
The science of ion beams goes back almost a century to the earliest explanations of radioactive particles transiting thin films The field is so rich that it is difficult for a non-expert to understand any of the current papers in the field. But basically, the stopping of ions in matter can not be calculated from first principles. Hidden in stopping theories are parameters which normalize calculated stopping powers to existing data.
Then some of the major parameters are reviewed and it will be shown how they are derived from experimental data. Examples are shell corrections , mean ionization potentials, the effective charge of ions and the Fermi velocity of solids.
Over papers have been published in the experimental stopping of ions in solids. Experimental measurements of stopping powers is a difficult task, and there is wide variation in the results.. Plots will show how existing stopping calculations compare to experimental data from these papers.
Since the stopping calculations are based in great part on theory, the interpolation of stopping powers between various ions and targets is often more accurate than individual measurements, especially for difficult targets.
