Run 24 pp and AuAu EMC timing
Run 24 pp timing:
1) Initial timing scans were done on run #25118040 from 27 April 2024:
Attached are the plts/timing analysis for the TCD settings for BTOW and ETOW.
a) BTOW had an average of the crate-by-crate scans of 121.0ns
b) the standard graphical ETOW analysis gave 105ns
both of these values are very close (~1 ns) to previous run settings.
c) the ESMD scan had operational problems and not analysis possible
2) Subsequently a cal_scan run #25121008 was taken using an altered global timing setting
a) the BTOW results here and here gave a TCD setting average of 123.5ns.
b) the corresponding ETOW results were 107ns
c) the ESMD plots are: 12S1-1S2 , 1S3-2P1 , 3S1-4S2 , 4S3-5P1 , 6S1-7S2 , 7S3-8P1 , 9S1-10S2 , 10S3-11P1 , with an average TCD setting of about 72 ns.
d) a table summarizing BTOW values for both the above runs is here .
3) The upshot of all this is we went back (-2.5ns) to the original global setting with TDC values: BTOW = 121ns, ETOW = 105ns, ESMD = 70ns.
Run 24 AuAu timing:
1) Timing scans were done on run #25280017 from 6 Oct 2024:Attached are the plts/timing analysis for:
a) BTOW crates here and here . b) ETOW crates here . c) BTOW fits summary is here .
2) The final TDD setting were determined as: BTOW = 120 ns and ETOW = 104 ns.
