Run 41_2 seems to show mostly noise (anti correlation) and here we see real ions (positive correlation. This is confirmed in our figure 4, where the statistics of DSSD#3 seems about doubled. The event rate per unit time in 41_2 shows a relatively flat top behavior characteristic of noise domination, where as our present one shows more jitter that could be characterized by light ion production and transport variation.</p> <p> </p>
