Optimization of Positron Capturing

• Thickness of the Tungsten target: 1.25 mm
• Beam size at Tungsten target: Gaussian, [math]\sigma_{x,y} = 3~mm[/math]

Optimization with ELEGANT Simulation on the Region from Gun Exit to Tungsten Target

[math] \epsilon_{x,y} = 13 \mu m[/math] (Not sure yet, need to be calculated)
