26 Oct :Barrel Calo at IP

22 Sept (?) :jacks released BT accessible !

remove top and central platforms

install mu-rail where possible

install cryo services through the BT. Now 5/8 cryorings are in position and 3 sections connected

install BMS mu chambers

install upper HS

Vacuum pumping in DecemberCooling at XMas

Full Test in February-March (it was end January)

1 Milan phys/tech always there

Recall:

The cold mass production in industry stopped. The contract with the was company cancelled and the work moved to CERN one year ago.ECT-A confirmed to be the first one to go to the pit

• All 16 coils and keystone boxes ready for assembly

• Assembly of ECT-A has started in July, cold mass is ready now.• Assembly in cryostat. End January 06.

• Vacuum tested in H191 in Feb. 06.

• Cooled down at 80k in B180•• Moved to the pit and Cooled down at 4K in May 06 (was March 06

ECT-C will followMajor problems solved

End Cap Toroids

SCT endcapAll SCT disks for the first end-cap (9/9) are finished (Liverpool), and they are well-advanced 3/9 for the second one (Nikhef)

The recovery from a failure of the end-cap LMTs (low mass tapes for electricalservices) is proceeding according to the plans (requiring fabrication of new LMTs)

Original half-shell need

Production delayed by delamination of barrel support staves. Solved.

44 staves/112 were completed

But now serious problem with corrosion of the cooling lines( see Chiara)

Critical ID piping : 6 weeks delayBut not only detectors! Also ID services are a challenge! Layout of the cooling lines were underestimated. Big effort from TC.

Plan to finish for the 23th of October (critical last 2 sectors 1 and 9)

PhysicsMain event was the Rome Atlas Physics workshopOccasion for the whole collaboration to review the status of the physics and detector performance studies:

The preparation effort was large:Full simulation and reconstruction of 8M events in two months using the Grid tools, events made available to the community in the form of AOD’s

The response of the community was exceptional :450 participants; 100 talks.

Next steps

Finalize analyses in for the Autumn physics week

Prepare for DC3 as the commissioning of the Atlas SW & Event Data Model


Main conclusions (GP)

User-driven production on the grid did deliver data, but required toomuch human intervention, need evolution in that sector

The transition G3/G4 is now accomplished, should continue validation, using CTB data

ATLAS framework usable for analyses, now need to address performance issues and evolving analysis tools according to feedbackreceived

Next steps

Finalize Analyses of the Rome sample (Autumn Atlas Physics week )Prepare for DC3 as a real commissioning test of SW&CItalian partecipation very good. Now we need to move the

community from MC data analyses to real analyses. Ideas of tutorials from computing and analyses tools to “workshops” were to merge internal existing experience on selected items to favorite the concentration of forces on relevants topics


Require Mwwithin 10 GeV of nominal W mass S/B = 1.77

Top mass (GeV)

m(t)

Ex: Top study with 1 week data!Selection cuts: ETmiss > 20 GeV, 1 lep Pt > 20 GeV, 4 jets Pt > 20 GeV

No trigger selection efficiency taken into account yet

Preliminary

Measured top mass 160.0 ± 1.0 GeV , stat error on xs: 8.3%

I progressi compiuti nell’ ultimo anno sono notevolissimi :Il toroide esiste ed i rivelatori sono o costruti o in fase molto avanzata. Inizia il commissioning

I problemi sono (quasi) quotidiani, ma la forza e capacità dei reazione della collaborazione sono sempre stati eccezionali.

La componente italiana come impegno, qualità e risultati non ha nulla da invidiare a nessuno. Inoltre si è rafforzata con l’ingresso del gruppo di Bologna.

Ad oggi c’è un ritardo di circa 2 mesi. La capacità di seguire la schedula dipenderà da moltissimi fattori in primis dalla capacità di modulazione e sincronizzazione delle operazioni di assemblaggio (devil is in the details)

Oggi il problema più acuto son i pixel, ma non sono uno show stopperSono ancora convinto che nel 2007 attraccheremo.

Quando? Chiedete alla Sibilla Cumana!

“Standard conditions”

Critical muon station readinessToday key issues:

• BOL chambers construction in Lecce/Rome

• BML initial production noise quality (RPC), how much rework?

• BOS new delamination of Al panels (repair solution found)

• Keep level of manpower at BB5 as today for the next 3-4 months

The new organization is in place and it seems this time to be ok!

ECA cooling down


EM Barrel BE Commissioning• CPU, ROD, TM, TBM and SPAC

Masters modules installed in all 8 EMB crates.

• All EMB crates were tested individually:

• Some RODs and TMs with errors:they have been replaced.

• All EMB modules should work!

• This represents achievement of a MAJOR milestone!!!

Cosmic in TRT


Next 2 months : HS archesThe top part of the arches will be pre-assembled into 3 large sections, and equipped with platforms and cable trays, already on surface.

Already installed.


Next 2 months : critical path22 Sept : BT jacks released

26 Oct : Calo barrel in

BT platforms removal

BMS Ce/C

HS arches Ce/C

Many activities running in parallel and superimposed

Critical delivery of material : rails, brackets, cable trays, gas manifolds, ..

Critical the readiness of the barrel calo : ID piping

BT current l. + cryoring (sec 5)

After calo barrel in (26 October to 22 Dec)

• Endcap C calorimeters assembly up to end Jan ‘06 on side C

• Connect BT services (vacuum, power, cryo, bus bars,…)

• Finish installation of mu-rails, mu-services, mu-installation tools

• Connect LAr/Solenoid Cryo services

• Install barrel muon chambers (6/day), from mid Nov on both sides

• Install calo services

• Install ID services (pipes and cables)

• Install cooling and gas racks + connections to in/out

• Commission detectors during installation (I.e. Calo in situ electronics,..)

• Maintain infrastructure operational



Schedule barrel• Driven by ID cabling dressing on calo flange (we assume

50cables/day)

• Hudge ID work with major unknowns (method, cables availability, sequence tuning,…)

• Plan to finish most chambers installation by Apr ‘06

• Plan to finish Calo C assembly by end Jan ‘06

• Calo C in by mid Feb ‘06

• Calo A start assembly Feb ‘06 to May ‘06

• Feb to Apr : magnets tests, solenoid field mapping


Forward region + ID• As soon as Calo C is in, install TAS shielding

• From end Feb ‘06 start Wheels C installation

• ECT C ready for installation from Sep ‘06

• As soon as Calo A is in, install TAS shielding

• ECT A ready for installation from mid Jun ‘06

• From Sep ‘06 we might start Wheels A installation

• Barrel ID installation end May ‘06 from side A

• ID A&C late summer ‘06


Forward region + ID• Interplay between ECTs and wheels to be optimised

• ECT C installation schedule & wheels A will strongly depend on experience on previous ECT A / Wheels C assembly

• We need to minimize LAr cold movements to avoid risks

• We need to minimize ECT risks, magnet test as soon as possible!

• We need to delay as much as possible the pixel installation (recent corrosion problems)

First discussions next week TMB/EB

Next 6 months planning to be fixed in Oct ATLAS week
