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.
| Material | Thickness | [math]\displaystyle{ \Delta t / \sqrt(12) }[/math] | Resolution | Excess straggling | Pre-straggling resolution | Layers for 230 MeV + [math]\displaystyle{ 5\sigma }[/math] |

| Al | 2 mm | 1.5 mm | 4.16 mm | 6.1% | 1.38 mm | 67 |
| Al | 3 mm | 2.1 mm | 4.26 mm | 9.2% | 1.69 mm | 48 |
