  1. Comparison of kapton and ink resistive detectors D. Attié, P. Colas, M. Dixit, Yun-Ha Shin, R. Woods TPC Tests Analysis Meeting, DESY 28 May 2009 Micromegas module

  2. Description of the detectors Resistive Kapton ResistiveInk Resistive Ink Resistive Kapton Prepreg Glue 1-2 μm Glue 1-2 μm Kapton PCB PCB - Resistive detectors comparison -

  3. Comparison at B=1T, z ~ 5 cm Resistive Kapton ResistiveInk • RUN 310 • vdrift = 230 cm/μs • Vmesh = 380 V • Peaking time: 500 ns • Frequency Sampling: 25 MHz • RUN 549 • Vdrift = 230 cm/μs • Vmesh = 360 V • Peaking time: 500 ns • Frequency Sampling: 25 MHz Dead pad: [row: 54; column: 18] - Resistive detectors comparison -

  4. Pad Response Functions ResistiveInk Γ = 6.6 mm Γ = 10.8 mm δ = 10.4 mm δ = 12.7 mm - Resistive detectors comparison - ResistiveKapton

  5. Spatial resolution at z = 4.3 cm Resistive Kapton ResistiveInk σ[z=4,3 cm] = 72 μm σ [z=4,3 cm] = 130 μm - Resistive detectors comparison -
