      data file R15

      ADC data item stats - attachments 26-27
       large variation in rates beam off/on

c. 10.30 beam off (for new FRS setting?)


11.25 analysis of data files R14_19 (beam ON) and R15_24 (beam OFF) - attachments 28-29

      For beam ON max deadtime c. 11% (aida04), beam OFF max deadtime c. 0.1% (aida04)

      Zero timewarps observed

      Notice large # of PAUSE/RESUME data items for aida03 & aida04 presumably due to additional overhead of processing the time machine scalers 

12.35 Beam off

      DSSSD bias & leakage current OK - attachment 30
       Can observe beam spill structure in DSSSD leakage currents - now slowly recovering with beam off
