Woes of a Project LeaderWoes of a Project Leader

• Life for a Project Leader isn’t easy:– Has to heard Lions! (not just Cats)– Has to organise people

• Who don’t want to be organised

– Has to give talks at important colateral functions– Has to set up agendas

• In every agenda– There is a First Talk

• Project Leader

– There is a Final Talk• Project Leader

– There are all the talks in between• The important people who do real work

– There is the Penultimate Talk• Extremely Dangerous:

You never know what he will say He will steal your best slides And he will say something about what you wanted to say …

» but probably not quite how you wanted to say it.

What does a System Run Coordinator Do?What does a System Run Coordinator Do?

• Represents you at the weekly meetings– Negociates time slots

• Combined running• Calibration

– Expresses the opinion of the management• Might sneak in one or two of his/her own

• Keeps track of and schedules system activities– In between beam fills– During “Technical Stops”

• Coordinates system configuration updates– Calibrations, firmware updates, patches, etc.

• An “Equivalent to” system run coordinator– Doesn’t know about OTP or OTSMOU

Calorimeter Trigger: Commissioning HistoryCalorimeter Trigger: Commissioning History

• Hardware:– 2007:

• Running in ATLAS since M3 (June 2007)– 2008:

• Installation complete Q1 2008

• LTPIs and combined partitions Q2 2008

• Ready for first physics Q3 2008

– 2009• Frequent cosmic running

All L1Calo triggers commissioned and running• Regular Wednesday LArg/L1Calo sessions

Refinements of timing Energy calibration Noise hunting

• Firmware consolidation Algorithms, readout Studies of problematic channels Now running combined digital-error free @ 85 kHz

• Optimized setup Digital filtering (FIR filters) for “bunch-crossing ID” (BCID)

• On to REAL Physics!

What is in a Run Report?What is in a Run Report?

• Summary of configurations– Calibrations– Triggers– Timings– Receiver settings– Bad channel history

• A look backward– 2009

• A look forward– 2010

What were we Expecting in 2009?What were we Expecting in 2009?

• And they played the game• More or less to plan

• In fact, better! • Beam arrived early …

Recorded data samples Number of Integrated luminosity events (< 30% uncertainty)

Total ~ 920k ~ 20 μb-1

With stable beams ( tracker fully on) ~ 540k ~ 12 μb-1

At √s=2.36 TeV (flat top) ~ 34k ≈ 1 μb-1

Average data-taking efficiency: ~ 90%

Max peak luminosity seen by ATLAS : ~ 7 x 1026 cm-2 s-1

Future Fun Future Fun

• Eddy currents and image currents– What happens to ATLAS when there is significant beam– Do you remember the hemispherical bump on a flat infinite plane?

• More energy and luminosity with trigger rates that are easy to see

– 2009 running wasn't really the year of L1Calo!

• Oh ... – and calibrations.
