ATLAS Barrel Calorimeter (LAr and Tiles)
Installation of the LAr and Tile Barrel
Calorimeters completed on the C-side The
installation of services electronics and services
has started

• Critical points
• Em
• FEB
• 6m delay partly recoverable
• Present plan Barrel FEBs by August, EC FEBs by
  November
• LV PS (MDI)
• Critical. Two proto in hands at BNL. Under test
• HV
• Hw Instable.Start being worrying. Task force in
  action
• Tile
• Super drawers
• completed and assembled by April. ok
• LV PS
• critical but two production lines (Cern and
  Prague) now

End-Cap C (EM HECFC )

• EC cryostat covers welded.
• Cool-down started end November.Filling and
  subcooling finished end January.
• The limits on temperature differences in the
  detectors were respected. Presently after 8 week
  cold testing period it is worming up. In pit in
  September
• Tile
• Extended Barrel C assembly in pit starting in
  September.

• End-Cap A (EM,HEC,FC)
• Integration status
• All calos inserted and cabled
• Welding of closed vessel almost finished (now)
• Closure of warm vessel in April
• Start cryo operations in June
• In pit end November (only two weeks tests in
  B180)
• Tile
• EB A assembly start in pit in November

End-Cap cryostat A before closure
FCAL A ready for insertion

Precision Muon chamber production
MDT (B EC) progressing well 22 muon stations
(MDT RPC) already installed CSC ( at large h)
already finished in September

Installation activity planning in the cavern
(part II)
10
Inner Detector- Barrel Pixels Progress on
all aspects of the sub-system for 3 layers On
schedule (v. C.Meroni) SCT Module assembling
of the 4 barrel cylinders ongoing B3 finished,
tested, and is now at CERN. 3/ dead
channels B5B6 in time. B4 late. Recovery
plan TRT All modules mounted and tested into
support structure. Electronic and cooling
partially installed Barrel tracker in the pit
March 06
First complete SCT barrel cylinder
TRT barrel support with all modules
11
End-CapTRT End Cap-C All wheels produced.
Stacking advanced and will terminate in
April End Cap-A Stacking will start in May .
Critical but still ok C-type wheels remain
staged (funding) It is possible that Atlas will
never have C-Wheels ( Stop workshops, Materials
etc.) If done insertion could be 2012 but
than. End-Cap SCT End Cap-C Disk 89
completed. Others are following. Tight but
ok. End Cap-A Late by 5m. Recovery plan in
construction EC-C in pit May 06 EC-A in pit
June 06
12
ATLAS End-Cap Toroids All 16 coils for both
ECTs are impregnated (where 10 in Assisi), and
the last ones will be delivered to CERN
now. Both ECT vacuum vessels have been at CERN
since long, including thermal shields and
super-insulations, as well as all components for
the assembly of the first ECT
The cold mass (single) assembly for the first one
(ECT-A) has started in Hall 191. Scheduled for
cold mass completion in May, insertion into
vacuum vessel in summer (on schedule), in the pit
in March06. EC-C will follow. Completion in
November 2005, in the pit in June06. No cryo
test on surface
13
Pre-assembly of the end-cap muon Big-Wheels

• TGC end-cap trigger chamber production is
• nearing completion
• Tooling available at CERN Preassembly starting in
  B180
• 72 TGC sectors and 32 MDT have to pre assembled
  from Q2 2005 to Q3 2006 (15 months)

Big-Wheel sector assembly tooling

Overall summary installation schedule version 7.0

Financial situation
No either good or bad news on financial status
cash flow problem expected, CtC confirmed,
deferrals mechanism slowly in action etc.
Updating expected at next RRB

ATLAS combined test beam in 2004

• All ATLAS sub-detectors
• integrated and run together with common DAQ.
• Gained lot of operation experience during 6
  month run
• Common ATLAS
• software used to analyze the data
• 90 million events collected
• 4.5 TB of data
• e?, ? ? 1 ? 250 GeV
• ? ?, ? ?, p up to 350 GeV
• g 30 GeV
• B-field 0 ? 1.4 T

Conclusions

• ATLAS progredisce bene e pianifica la chiusura
  del rivelatore per Aprile 2007
• Tutti i rivelatori stanno facendo il massimo per
  rispettare la tempistica della V7.0 anche se
  obbiettivamente i tempi sono molto stretti, si
  stanno anche prendendo dei rischi e non ci sono
  margini
• Sicuramente con un sistema così complesso
  arriveranno inconvenienti, ma fino ad oggi la
  collaborazione ha mostrato una grande capacità di
  reazione.
• Il lungo periodo di costruzione sta terminando e
  latmosfera si fa eccitante
• Atlas Italia (giovani e meno giovani) è
  pienamente motivata
• Abbiamo bisogno della vostra critica, ma anche
  del vostro pieno supporto (come già avuto ) per
  mettere a frutto il notevolissimo contributo dato
  fino ad oggi
