Reminder: Cosmic Trigger (WP 6.1) • 4 Chicago coincidence trigger board constructed
– (LAr also interested in building additional boards if needed for endcaps)– With 4 boards in hand: 4 * 12 = 48 superdrawers (8 towers / SD)– Connection now via transition board to temporary TileCal trigger cables in
USA15, Level -1 racks– Permanent rack location reserved in USA15 Level -2 racks next to LVL1-Calo
Patch panels– Need to construct intermediate cables from Patch panels (time + manpower)
• Also split LB + EB signals to 2 coincidence boards– Second set of 4 transition boards being constructed for outputs from LVL1-

Discussion• Informal TileCal + LAr Meeting held at CERN
~month ago– TileCal: Phase 2 + 3 coordinators + subsystem
experts + …– LAr: Phase 3 Barrel + Endcap coordinators +
subsystem experts + PL + ...• Learned that external scintillators at IP are not
an attractive option for LAr– At most 2-3 weeks available in Fall ’06
• Outcome: LAr will produce a document to be reviewed by TileCal + Institute Board– See attached document + questions at end of this talk
Nov. 2005 Calorimeter Commissioning R. Teuscher 13
• First of all the clear goal of the barrel phase 3 commissioning is to demonstrate that the detector can operate in a stable mode during months.
• Full detector calibration– Demonstrate software calibration + db is working !– Will start in February 2006 (as soon as the barrel cryostat is cold)– Needs to be fully operational before cosmic muons run starts– Pedestal, Ramps, Calibration pulses + OFCs– COOL/POOL db integration– Monitoring + Bad cells at calibration level
• Bad physics signal shape– Define “bad” signals in Physics with seeking algorithms +
monitoring– Cross check calibration level results with results from the
installation, and cold commissioning in B180

Muon signal in barrel EM calorimeterDue to Accordion geometry, muons are reconstructed in middle compartmentby summing two cells in .
Note : S/N ratio too small in strip and back compartments

With 10000 events, muon signal can be measured with ~ 0.3% precision

ATLAS Commissioning View: Main steps up to spring cosmics
(G. Mornacchi + P. Perrodo – ATLAS Overview Week, Paris, October ‘05)
• Intermediate steps– Individual barrel calorimeter partitions
• Integration with DAQ (ROS system)• Event building and data recording• Individual DCS systems operational• Monitoring and analysis
– E.g. local (at P1) analysis of data from a run– Infrastructure for local analysis– Detector software for analysis
• Data bases: access• Surface proto-control room
– Combined calorimeters• Common trigger distribution (LTPs, CTP)• Common central DCS (e.g. alarms)• Surface proto-control room
• Combined barrel calorimeters, cosmic run (May 06)– Cosmic trigger– Analysis software

• Amplitude inter-calibration in – Summing modules in
• Time inter-calibration– Energy/time rec. with OFC needs pulse vs 40 MHz clock phase– Cross-check relative timing of middle layer cell predicted at ~0.8 ns
(calibration pulses + cables lengths, systematics, t.o.f.)• The pulse versus 40MHz clock phase will be delivered by the TileCal time
reconstruction. We need an accuracy around 1.5ns.• This time phase (corrected for the time of flight of a muon from the IP) needs to
be independent on eta and phi (i.e. independent of the Tile trigger tower)– Intercalibration of the timing of different TileCal trigger towers is very important.– Will be checked with the data of the TileCal September expert week.
• LAr EM Positioning – ~ 0.025/8/12 in using strips– ~ 0.025/10 in with middle cells
• Study ‘high’ energy events (above ~2 GeV)• Extract drift time from 32 sample events
LAr Goals for Cosmic Runs (2/2)(M. Aleksa)
Nov. 2005 Calorimeter Commissioning R. Teuscher 22
• Amplitude inter-calibration in – Per cell: /N/290 MeV – Uniformity: /<E> ~ 0.5% with 40000 /cell– Group cells in (48) 1000 /cell
• Time inter-calibration– 100 /cell, can check physics timing at 0.6 ns
• LAr EM Positioning to be investigated• Events above ~2 GeV to be investigated• Drift time from 32 sample events to be
investigatedG3 results: projective 0.042±0.005 Hz, pseudo-projective 0.153±0.010 Hz
100 µ/cell 106 full days (29) with 1.0 GeV Tile threshold, =±0.1, =120.1
projective 0.027±0.004 Hz, pseudo-projective 0.098±0.008 Hz
165 full days (45) with 1.5 GeV Tile threshold (3840 top cells)
LAr Data taking(M. Aleksa)
• At least 100 days of data-taking necessary to obtain useful results• Our preferred trigger would be single-tower trigger (on bottom modules)• Then we could in principle take data with only 2 trigger board (sharing with EC possible)!
Nov. 2005 Calorimeter Commissioning R. Teuscher 23
Questions from LAr to TileCal1. Is it possible to trigger and read independently the Tile
barrel and extended barrel(s)?• Answer: Trigger: Yes, it is possible. A cable / splitter would be
needed to split the LB/EB signals from the LVL1-Calo patch panels to two separate Chicago transition modules. Readout: Yes. The ROD readout is grouped by TTC partitions, and LB/EB are separate partitions. Event building would be necessary.
2. It might be useful to trigger on the barrel in order to have projective muons in the LAr endcap.
• Answer: Could be difficult, required LB+EB to be in final position. During many periods in ’06 the EB’s are scheduled to be moved back and forth in z for muon big wheel installation etc. Some “quiet periods” should be checked.
Nov. 2005 Calorimeter Commissioning R. Teuscher 24
Questions from LAr to TileCal (cont.)
3. LAr plans to have 4 experts on call (Front End + cooling, Backend + Online, DCS + interlock, Monitoring + offline), can a similar effort be provided by the TileCal group over a long period while some work will have to be done on the extended barrels?
• Answer: Comments invited from all TileCal members + Institute Board
4. Should dedicated expert meetings / discussion start before the end of the year?
• Depends on positive answer from TileCal. Last dedicated meeting was very productive. Useful to coordinate with ATLAS weekly commissioning meetings.
• Question to LAr: Help with manufacture of 48 intermediate trigger cables + connectors in USA15 from LVL1-Calo Patch Panels to coincidence boards?
Nov. 2005 Calorimeter Commissioning R. Teuscher 25
