KEK Beam Test Results Resistive Foil

This report presents comprehensive results from KEK beam tests focusing on resistive foil performance across multiple international institutions, including Japan, Canada, France, and Germany. Key findings include resolution results for ArIso and CO2, bias analysis, and drift velocity measurements. The data indicate consistent resolution results and highlight the need for further bias studies and more refined Pad Response Function fittings. Calculations of drift velocity align with Magboltz simulations, underscoring the study's reliability.

  2. Outline • Resolution results for ArIso and CO2 • Bias results • Residual vs. X • PRF • Drift Velocity

  3. Resolution σ0 = 104 +/- 3 μm Neff = 41 +/- 12 μm row 7

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

  5. Resolution σ0 = 87 +/- 3 μm Neff = 30 +/- 5 μm row 7

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

  7. Resolution Resolution [mm] σ0 = 108 +/- 5 μm Neff = 34 +/- 10 μm Drift Distance [mm] row 7

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

  9. Bias bias not corrected for

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

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

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

  13. Drift Velocity

  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
