Analysis of S4200 in offline sort lead to conclusion that specttrum is dominated by protons, 8MeV punchthrough visible??.Not many events at high energies, where Alex MC predicts them to be.</p> <p>2.Noticed that 3 channels in particular in S2-2 have very high rates. All in same bank - can we raise thresholds?&nbsp; Strips 34,36,46 in S2-2, we think (from mapping in sort code)</p> <p>3.&nbsp; The loci in the E vs T spectrum are (a) still aparrently upside down from what expected and (b) very wide in time. There is also a suspiciously sharp edge to the timing peak. Look at eny E vs T loci in the sort</p> <p>4.Been sorting over night - nearly caught up.</p> <p>We looked a run (54) from the first H2 run at 4.4 MeV/u and compared with the current data. The The S4200 spectrum and the E vs T loci look exactly the same.</p> <p>&nbsp;</p> <p>&nbsp;</p> Encoding: HTML   ELCode   plain   Suppress Email notification          Resubmit as new entry Attachment 1:
