TDR: Total Data Readout

TDR allows each channel to be run independently, and then be associated in software for event reconstruction. Such a solution is possible as each data word is associated with a time-stamp generated by a global 100MHz clock. This allows all of the data from the target position and the focal plane to be collected with virtually no system dead time loses.

The correlation of events is defined in software by the physicist using the spatial and temporal constraints determined by the experiment being performed. This correlation can be as simple or as complex as the user decides, a simple example would be to start with the identification of recoils then to look back in time using a window centered on the time of flight of the recoils, for the gamma rays detected during that window. A more complex example would add in correlations between the decays of the implanted recoils before the data were stored.
