SGP/RL/C1 - Data acquisition system malfunction
DataStreams:sgprlC1.a0
Description:
Due to a malfunction in the data acquisition system, the narrow-field-of-view (N2, Dep, 
Copol, H2O, T1, and T2) photon counting signals experienced frequent intermittent drop outs 
during this period. The problem was solved when the 15-V power supply in one of the 
data-acquisition racks was replaced.
Measurements:sgprlC1.a0:
  • Merged count rate for water counts high(water_counts_high)
  • Merged count rate for t1 counts high(t1_counts_high)
  • liquid_counts_high
  • Merged count rate for elastic high channel(elastic_counts_high)
  • Merged count rate for nitrogen counts high(nitrogen_counts_high)
  • Merged count rate(depolarization_counts_high)
  • Merged count rate for t2 counts high(t2_counts_high)
