Optimum Delay

The optimum delay was calculated for each tower using the laser data, runs 1025-1030. For each run the delay was increased by 16 ns (Range: 0-80 ns). The optimum delay for each tower was calculated by finding a mean ADC value for each run and assuming a quadratic shape. Figure 1 below shows the means for tower 05TD01. From these data points, an optimum delay of 34.3371 ns was calculated. This was done for every tower.

Figure 1: Shows the mean ADC dependence on the delay for tower 05TD01.



Figure 2: Shows the correlation between eta and the optimum delay for all 720 towers.



Figure 3: Shows the correlation between eta and the optimum delay for all six crates.
