Comments:
---------
SciFi are off and warm, as we are trying to decontaminate the refrigerator.
Despite this, 3 DYC  (3 and 5) hangs occured, the last (7:35) for sync problem

5:38  Straws HV trip.
5:38  Target nozzle regenerated, after a 20% smooth drop in rate; 
      after regeneration, rho went up to 3e14, (L=2.7e31), and finally
      stabilized to ~2.6e14. 
6:45  Straws HV trip, and sudden 30% drop of rate (target rho constant),
      correlated to a beam lifetime drop (from 0.6 mA/h to 2 mA/h);
      probably an orbit shift. Back to normal after 2 minutes.
      Does not seem related to any MCR activities (checked by phone)

shift.
