  1. RP beam tests in H8 Ayah Massoud Jan Kaspar Hubert Niewiadomski

  2. RP 1, det. 3 • Tests of 2 Roman Pots, 10 CTS detectors in each • General performance tests (signal, noise) • results as before • RP 1: one detector with 2 noisy strips, one detector partially not readible • RP 2: all dets. ok strip RP 1, det. 6 RP 1 strip

  3. Track selection and noise rejection Number of clusters per track per projection Due to dead strips in det. 6 Due to noisy strips in det. 3 1) Reject all events with less than 3 active planes in any projection. 2) Apply track search and select hits (clusters) belonging to the recognized track. 3) Reject all events with less than 3 active planes in any projection.

  4. Typical working detector, RP1 95% Beam profile Cluster size 4% strip number of strips in a cluster Correlation plot, Dets. 1 and 9 Correlation plot, Dets. 1 and 5 • - Alignmnet precision • better than one strip • Clean signal • Good noise rejection • of the noisy strips Position [strips] Position [strips] Position [strips] Position [strips]

  5. Efficiency of a single detector • Efficiency estimated on the basis of one pot • Reference tracks: at least 6 out of 9 detectors with hits in a common region Efficiency, det. 6, RP 1 Efficiency, det. 5, RP 1 Position [strips] Position [strips]

  6. Efficiency of a single detector RP2 efficiency (threshold 10) RP2 efficiency (threshold 15) Position [strips] Position [strips]
