10.45 DSSSD bias & leakage currents - see attachments 1 & 2
       note - significant increase in leakage current (~0.8uA) since previous readings
              may be temperature transient or charging effect due to delta electrons due to BigRIPS tuning to F11
              15cm Pb installed upstream of AIDA+BRIKEN some days ago
      FEE64 temperatures OK - see attachment 3

15.35 DSSD bias and leakage currents ok (attachments 4+5).
      Marginal increase over this morning.
      FEE temps ok (attachment 6).
