| - | 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. | ||

| - | 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. I have David Radford's correction code, and am working as a first step to implement the correction in my own Mode3 data-sorting code. Once this is successfully implemented, I will talk to Mario/Carl about implementing the corrections in the pre-processor. I am aiming to have a working offline correction and will update on the progress by next Wednesday, May 23rd. | ||
