First plot above shows the signals (from bottom to top) from the first chamber wires, first chamber cathodes, and second chamber cathodes, when using 90Sr source; a second cell wire used for triggering. The max drift time (>8usec) looks bigger than expected from Garfield ~5 usec. This indicates different gas mixture (nominally 90/10 Ar/CO2) or weaker fields. Second plot shows a result with 55Fe source: total charge on x vs width of the signal in time, the later estimated by the (total charge)/(max amplitude). |
