2. Outline Resolution results for ArIso and CO 2 Bias results Residual vs. X PRF Drift Velocity

3. Resolution σ 0 = 104 +/- 3 μm N eff = 41 +/- 12 μm row 7

4. Resolution – multiple rows together Drift Distance [mm] Resolution [mm]

5. Resolution σ 0 = 87 +/- 3 μm N eff = 30 +/- 5 μm row 7

6. Resolution – multiple rows together Drift Distance [mm] Resolution [mm]

7. Resolution σ 0 = 108 +/- 5 μm N eff = 34 +/- 10 μm row 7 Drift Distance [mm] Resolution [mm]

8. Resolution – multiple rows together Drift Distance [mm] Resolution [mm]

9. Bias bias not corrected for

10. Residual vs. X-track (1T) no large edge effects

11. Pad Response Function (1T) Distance (mm) Amplitude Not yet fitted for, some difficulties with paw fits

12. Pad Response Function (1T) Distance (mm) Amplitude Not yet fitted for, some difficulties with paw fits

13. Drift Velocity Gas V drift (cm/  s)Magboltz(cm/  s) ArIso 80 V/cm2.95 ± 0.082.95 ± 0.01 ArIso 220 V/cm4.19 ± 0.124.17 ± 0.01 TDR (super preliminary) 3.4 ± 0.33.58 ± 0.01 CO 2 Too slow for electronics to measure

14. Average amplitude vs. Row # Amplitude 6-9% variation in amplitude for inner rows

15. Conclusion Resolution results consistent for ArIso and CO2 More bias studies PRF needs to be fitted properly, more time with PAW Drift velocity calculations accurate and agree with magboltz
