We roughly adjusted the timing based on attachment 1, for ions to be in center of electron cooler (east arc), corrected for PMTs being 2.5m closer to the north on the west arc
then did a new 30 injection accumulation (10.8k counts on particle detector) and readjusted the timing to fine tune this
(attachment 2, first settings right peaks, adjusted towards left)

Then we did a 60 injection accumulation (only 7.6k counts?) to check the settings and shift the timing by half a revolution (324 ns = 98 bins)
(attachment 3, data saved in /data.local2/2025_229Th/2025_229ThDAQ1_0099.lmd with DAQ1).

Checked these settings and particle counts with another injection (2.8k counts)
(attachment 4, data saved in /data.local2/2025_229Th/2025_229ThDAQ1_0100.lmd with DAQ1)


Estimated bunch width: 20bins = 67ns;corresponds to 20/200 of 1 evolution, so about 12m
                                     assuming v+0.5c0: 11m
