2025 bad spills
During the 2025 run we observed several DAQ issues.
For some events, the data size reported by a single WB was 4x 32b words (3x header, 1x trailer), since all channels were zero-suppressed. Due to an incompatibility with the event format expected by DHUMX, this created an issues. When the issue happened, for the subsequent event in the same spill (and possibly in following spills), the data from that WB was completely lost. The error was solved later in the run by disabling, for each WB, the zero suppression for one channel (for 2026, we plan to fix the DAQ error moving to the new data format, see: https://gitlab.cern.ch/POKER_NA64/waveboard_ucf_na64/-/issues/53)
Due to TCS issues, also, we observed events in which one or more event source (FE DHMUX) was completely missing. This should never happen, since the FE DHMUX should report, at least, the header and trailer words. If data from a given front-end DHMUX is completely missing, this event and the following ones must be completely skipped.
