  4. Events of Interest • 12.20 • erratic L1/L2 and sometimes L3 rates • CTT (and pauses for SMT) • Calorimeter noise • unexplained • prescale area/Change.log file for complete list of changes • 45E30 over L3 rate cap • no solenoid run • due to He compressor failure • special trigger list ? • High level Trigger Jamboree (August 4, 2003) • see ‘tutorial’ link from the Operations page • Anatomy and Operations of a global Trigger List • Exposure Group Rules – Special Trigger Mtg (Aug 12,2003) • see TM talks page for current rules.
