  1. Preliminary Results for T5, T6, T7, and T8 Emmanuel Angulo (CSU Fresno)

  2. Gas Gain for T5-T8

  3. T5 Uniformity Connector 2 Connector 1 Connector 1 Middle point 4cm x 5cm Corner points 1cm x 1cm Connector 2 Connector 1

  4. T6 Uniformity Connector 2 Connector 2 Connector 1 Connector 2 Middle point 6cm x 5cm Corner points 1cm x 1cm Connector 2 Connector 1 Noise up to Ch 140 for connector 2 (This chamber was damaged at a pillar and George fixed it)

  5. T7 Uniformity Connector 2 Connector 1 Connector 1 Middle point 4cm x 5cm Corner points 1cm x 1cm Connector 2 Connector 1

  6. T8 Uniformity Connector 2 Connector 1 Connector 1 Middle point 4cm x 5cm Noise up to Ch 143 (Bad signal with connector 2) Corner points 1cm x 1cm Connector 2 Connector 1

  7. Charge Up Note: There is approximately a 5 second delay in between data points

  8. Conclusion • Gas Gain is good for all chambers • T5 and T7 have good spectrums and are fairly uniform • T6 seems to have a problem with connector 2 (strips 129 to 256), needs more testing • T8 has a bad middle region, needs more testing • The high charge up is consistent for the chambers with a ground mesh but only for the first 140 seconds (+ 45 seconds)
