Outline FADC and TDC Data: – Mott_SemiInt Mode: 7860 – Mott_Sample Mode: 7859 Direct and Delayed Analysis: – No Delay: 7821 – Delay = 8:

Mott_SemiInt – Run

4 FADC Time

Mott_Sample – Run

Run 7821 – No Delay 7 Mott Asym UD (%) = ± 0.78 Mott Asym LR (%) = 1.35 ± 0.77 UD Instrumental (Detector Efficiency and Solid Angle) A1x (%) = -8.17± 0.79 LR Instrumental (Detector Efficiency and Solid Angle) A1y (%) = ± 0.77 UD Instrumental (Beam Current and Target Thickness) A2x (%) = 1.09 ± 0.79 LR Instrumental (Beam Current and Target Thickness) A2y (%) = ± 0.77

Run 7822 – Delay = 8 8 Mott Asym UD (%) = ± 0.66 Mott Asym LR (%) = ± 0.66 UD Instrumental (Detector Efficiency and Solid Angle) A1x (%) = -9.15± 0.67 LR Instrumental (Detector Efficiency and Solid Angle) A1y (%) = 0.90 ± 0.66 UD Instrumental (Beam Current and Target Thickness) A2x (%) = 0.70 ± 0.67 LR Instrumental (Beam Current and Target Thickness) A2y (%) = ± 0.66

Summary Semi_Int Mode has approximately similar energy resolution as Mott_Sample mode Delayed analysis seems to work – need more data to be sure 9
