Comments:• Sequence of chamber installation needs to be aligned to chamber production/dressing schedule.• We should try to accelerate the installation of the chambers on the PZ-side, to finish before the sector test.

Platforms and staircases behind M5 (US-side):Integration and Installation

• Scaffolding for the cryo-line has been removed, despite the fact that the tests are not completed. . .-> Installation of the staircases and platforms started.


Platforms and staircases behind M5 (PZ- side):Integration and Installation

• Design ready • Price Enquiry being launched• Installation could earliest start December 1, 2005


General Support Structures:Integration and Installation

Delivery of preassembled components this week.

Work on traction system not finished.

Nacelles need ‘certificate of conformity’ to be approved by the safety commission.


Proposed schedule:1. Refurbishing of zone behind M5 US-side: 10.10 – 24.10

PZ-side: 10.12 – 13.1.062. Mounting general support structure US-side 24.10 – 14.11 PZ-side: 16.1.06 – 31.1.063. Installation chamber structure (LNF) US-side: 12.1.06 – 10.2.

PZ-side: 13.2.06 – 10.3.064. Integration of nacelles and guiding system1.12 - 22.12

-> Only possible if the open safety issues don’t cause a delay (visit to company scheduled for Friday). 5. On detector cabling, gas piping M4/M5: 30.1.06 – 10.3.06

-> Cables for M2/M3 come only in Feb’06, installation only in April ’06-> Conflict with chamber installation, starting at the same time, due to nacelles, needed for both tasks.-> We have to consider buying a 3rd nacelle !

Installation of Services


Conclusions

• The installation of the M2-M5 infrastructure is on the critical path.

• With the open questions (e.g. on the nacelles and the cable quality) it is difficult to take the decisions required to bring the project back on schedule.


Cabling:Good news: - Best bidder for cable well within our budget - Positive experience of CMS, but not on big samples Bad news: - Prototypes have to be done.

Plan (agreed with Adalberto and CERN purchase office): - Order ~10% of LVDS and ~15% of ECS cables (for M4/M5 cryo side)-> Allows to avoid delay in chamber installation (which will start with M5 cryo side). -> In case of unexpected problems with prototype, financial losses are limited, while schedule problems are then unavoidable.Similar situation for HV-cables (same company).Situation with LV-cables to be clarified further.



On detector Gas Piping:• Progress in LNF (Emiliano, Massimo)

on design of distribution box.

• Gas pipes of PEEK type turned outto be MUCH too expensive(~15 × more expensive than copper)

->Optimized design now being finalized (meet next week)->Validation tests can hopefully been done within the next 3-4

weeks



Impedance (Δp) adaptation requirement: • Ensure an equal pressure drop of about 1mbar for

each individual chamber. • Old scheme:

• New scheme:

Cooling:• Reminder about power consumption:

• Reminder of cooling strategy:

• The chambers in regions R1 and R2 have up to 24 FE-boards/chamber and hence quite a large power consumption on a small area

->We foresee to have a sort of air cooling, where air of about 17oC is blown into or around the chambers in R1 and R2 in stations M1-M3

Cooling for FE-boards:• In order to avoid hot spots close to the beam pipe, air blowers are

foreseen for both sides, providing an airflow of about 400m3/h (this would be enough to remove about 2.5kW of dissipated power by air.

• Distribution principle:

Temperature reduction due to cooling:ΔT2,3 ~ 7.5oC

Hoses have 30mm diameter

• Something similar is planned for M1• Cost estimate: ~30kCHF• Schedule: Blowers for M2-M3 ready for installation in January 2006
