I was setting up the analysis on merlin to look at the
autocorrelations, but I see Bernhard has already posted
these. At a glance (Bernhard's post) I would say that
ePC1 is fine at 2600 V. ePC2 could probably be run at
2850, right? The autocorrelations do not look too much
worse at the higher voltage, and the efficiency is
significantly better. Could the thresholds of some of
the ePC2 inner cathodes be raised, without hurting the
efficiency, to improve the long-time autocorrelations?
Best regards,
Steven
