  1. some results fromone beam splash eventfrom 2008part II Run 61628 Event 4969 A. Kubik & M. Schmitt

  2. We used a file from last year to develop some analysis code. • run 61628, event 4969 • The file has 53 cosmic ray events with real CSC activity, and one beam splash event. • The cosmic ray events have typically 100 – 300 strips, while the monster event has more than 163k strips. • These results are spurred by Jay’s stated plan for timing studies. See ppt from yesterday for first results. A. Kubik & M. Schmitt

  3. check timing for monster event • this is the “tbin” from the wire digi All chambers in ME-2/1 one splash event cosmic rays time slices A. Kubik & M. Schmitt

  4. define a “qsum” by summing all baseline-subtracted ADC readings for time slices 2 – 7 (we start counting with “0”). • look only at layer 3 • the layers tend to be all the same • horizontal axis is the strip number going around the ring starting at phi = 0 is the 1st strip in chamber 1. • plots show that inner chambers are saturated, outer chambers mostly are not A. Kubik & M. Schmitt

  5. This is the same information as on the previous page, presented differently. A. Kubik & M. Schmitt

  6. All eight stations A. Kubik & M. Schmitt
