1. Accessing PBeast and monitoring the L1 trigger Emily Thompson

3. 25 ns between bunches = 40 MHz Data storage rate= 1kHz Level 1 (Hardware) Level 2 (Software) Event Filter (Rebuilds events)

4. My projects: 1. Design and implement better way to access PBeast Stores ATLAS conditions data Why? Analyze quality of data Long term analysis Faster debugging Old: 5 arguments, hard to find New: 2 arguments (run and luminosity block number), readily accessible

5. My projects 2. Improve the monitoring of the L1 Trigger: L1a Rate, busy percentages, source of deadtime
