Severity

Scientific potential is reduced if 10MeV range doesn't provide good linearity in energy.

Problem

DNL of digitizers screw linearity, causing residue of >3keV for calibration function.

Progress

5/18/12: Before the electronics were turned off at Berkeley, we completed the required pulser measurements to extract absolute non-linearity measurements for all 1120 ADC channels. At this point, conversion from raw trace data to a useful non-linearity measurement is complete. David Radford's correction code, is being implemented the correction in offline Mode3 data-sorting code. Once successfully implemented, will discuss with Mario/Carl re: implementing in the pre-processor.
