The software for this project is Gate installation and the DTC toolkit. For a complete guide to use the software for optimization, see the page Software for design optimization.
Results
All following values are given in units of Water Equivalent Thickness!
Pre-straggling resolution is the contribution to the total resolution from the detector smearing. This is calculable because we know the range straggling from Monte Carlo simulations, and the pre-straggling resolution is a subtraction in quadrature.
