| <p>Comparison strip 6 amplitude spectra anew (red) vs (old) processing (Screenshot). Slight shift in amplitude and slightly less counts with new processing in t+alpha peaks (1% level). This could be either due to less noise background, shift in neutron energy calibration (amplitude spectra shown with a cut of 100 keV). pdf plot shows new vs old for neutron energy vs counts. only minor differences at low neutron energy, new processing makes spectra cleaner at higher energy.</p>
<p>Shape of the Li 240 keV resonance is shifted in new processing - either due to different offset in tof-ene calibration, or time stamp for signals in one of the processing versions is wrong. Need a new comparison to simulated spectra. </p> |
