Geometry and segmentation optimization of the Digital Tracking Calorimeter

Optimization philosophy

Geometry

Materials

Software

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!

How many layers are needed?

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) !! Resolution !! Excess straggling !! Pre-straggling resolution !! Layers for 230 MeV + \lt math\gt 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
Al	4 mm	2.7 mm	4.35 mm	12.4%	1.97 mm	39
Al	5 mm	3.3 mm
Al	6 mm	3.9 mm
Al	7 mm	4.5 mm
