FADC status update E. Litvinovich1,2, G. Lukyanchenko1 1 NRC Kurchatov Institute 2 National Research Nuclear University “MEPhI” BX general meeting May 14, 2014, Sestri Levante
General status • DAQ is stable, duty cycle since last GM 99% • FADC system has been passed to shifter’s hands (Egor, Marcin, Chiara and myself) • Everything related to FADC for shifters has been documented and available at bxweb • FADC data were reprocessed in cycle_16 in MSU and revalidated in order to make merging possible • FADC-Echidna merging done (Egor) • Tests are in progress (Egor, Francesco, Nicola) • Put in production chain soon
DAQ shift procedure extended • FADC system operates autonomously and requires minimal shifter’s attention • FADC run coincides with main one and started synchronously • Production is done within bx_production chain • 30 s cpu time @ 6 h. long run • It’s very important to check output logfile! • Data validation • Check text output • Check histograms
Data production Keyword errors mean data corruption ADC buffers overflow, just note if they were
Data validation FADC threshold
FADC data merging into bxtree • Standalone program for merging events from FADC rootfiles into Echidna rootfiles or DSTs was made and tested • Program correlates FADC events with Echidna ones based on BTB event number supplied to FADC hardware • If several FADC events are present for single Echidna event, FADC clusters and waveforms are merged into one event • In the merged bxtree FADC event is available via GetFwfd() method of BxEvent • Work is underway to put merging into production
FADC mini workshop in GS • Any day(s) within 27/05 – 05/06 in GS • Goal is to make people familiar with FADC data • Mainly with respect to CNO/pep task, but we can consider other items, if any • Everybody interested is welcome
GRBs and DSNB • Maria Toropova is finalizing GRB analysis with respect to electron neutrinos • In contact with Sandra. Somebody else interested in this analysis? • This task alone is not enough for a paper. • Diffuse SN background • Aldo started this work yet in 2010 with the conclusion that we could set the limit (antinues) within yet unexplored energy region (Super-K & SNO limits are within 20+ MeV) • Time to revive analysis? • DSNB+GRB paper looks stronger
