1. Test Pulse Neighbors #2 Carl Goodrich 9/11/07

2. Effect on Channels 6 and 21 Links 1, 4, 7, 10, … –Double-Gaussian distribution Approximately symmetric about 0 (mean ≈ 0) –Observed for all Phi detectors in multiple HP2 runs –Not due to strip induced cross-talk

3. Signal of Neighboring Channels HP2 TP run, TELL1 51, link 13 –Look at neighbors of channel 4 Test pulse signal for channel 4 –Mean: -38.22RMS: 1.227 Change in signal in neighboring channels is 3 orders of magnitude less than the TP signal

4. Signal of Neighboring Channels Mean: -0.014 RMS: 2.127 Mean: 0.016 RMS: 2.241 Mean: -0.023 RMS: 2.191 Mean: -0.034 RMS: 2.202 Mean: -0.015 RMS: 2.571 Mean: 0.024 RMS: 5.294 Mean: 0.001 RMS: 2.230 Mean: -0.036 RMS: 2.127 TELL1 51, link 13, about channel 4, HP2 TP run
