Data Analysis - Timing Windows and Reference Times

Reference Times

The reference times must be determined before moving onto the timing windows. We use multihit TDCs and ADCs, which can have multiple hits recorded. Given the rate of physics triggers, and the wide width of the drift chamber reference time, it is quite likely the wrong hit is taken. We shrink the timing windows by cutting on the raw adc or tdc spectra
