TORINO: first table commissioning begin end of March ,first SL
(Amedeo ?)
5 chambers (10 SLs) are needed before end of 2003.

14. PARTS FOR CHAMBER COMPLETION AT ISR:
RPC pads : available in the labs. and at ISR
Gas and cooling pipes and manifolds :available by end 2002
Alignment LED forks available
HV cables : available for the 72 ch. ~ planned in March 2003
(Started end Feb. in Legnaro with people from IHEP Beijing, progressing well but full lot available in June) 30 chambers more ~ Sept (?) from IHEP
Hard problems with Customs. Could be solved moving cable manufacturing under LHC agreement umbrella
First complete Barrel DT chamber planned for the week of MAY 12
In the same week first installation of a MB2 Minicrate on an installed
Chamber.
First complete Minicrate (MB1) under assembly/test in Padova for the test

16. The firm has a delay of 6 months ,best case 400 available in June
MINICRATE STATUS
Mass MINICRATE assembly should begin in September and reach 12 MC/month in a couple of months.
 We need 21 MINICRATES by Jan Trigger Boards PHI 40 Tr.b. THETA
This imply BTI modules
================= BTI modules now on the critical path ==================
The firm has a delay of 6 months ,best case 400 available in June
400 BTIm allow the assembly of 50 Trigger Boards
50 Trigger boards allow to assemble 10 ~ 12 Minicrates
This would cover MC assembly in September and October if the firm delivers the TRB preserie early in September.
Then the TRB factory should deliver 200 boards/month .i.e. it needs 1600 BTIm/month.
But the assembly rate of 12 MC/month requires only 84 TRB/month i.e 673 BTIm/month

Realistic estimate => 12 Sectors installed in 2003
DT chambers are sector specific => Fix Installation sequence
Minicrates are on the critical path => Assume late arrival
Install chambers without minicrates in accessible sectors:

Install chambers without minicrates in YB0 8=> (21ch)
and with minicrates on YB => (21ch)
Equip Sectors 8 => 12 YB0, YB+2, YB+1, Sectors 8+9 of YB-1 with minicrates as they become available

21. CRITICAL ITEMS FOR INSTALLATION: Availability of HV Cables
Availability of MB1 supports
Availability of RPC
See above
Drawings should be ready in May to have the supports from
IHEP in October (integration and draftman problem).
Note that YB0 has the MB1 supports built in.
22/04/2019

22. RPC : still in the critical path.
wrt November 2002 a big step forward was made:
assembly of chambers started in GT (but rate should be higher)
a new firm was found (and approved) ,assembly starting now.
The case will be discussed in the INFN Scientific Committee of April
1st and 2nd and the impact on the detailed installation sequence in 2003
in the Barrel MU Week of April 9 to 12 in Bologna.
The actual status of the production is shown in the next slides.

( Figures from different tables : consistent within less than 100 KChF )
The deficit is fully consistent with the expenses done to purchase spares for ASICS,
Boards etc..in view of 10 years operation at LHC and “mechanical” parts for spare
Detectors. A large fraction of these expenses were done before the RRB agreed
that they can be part of the M&O B.

32. Le percentuali indicate per gli ASICS sono la parte eccedente
The items enlisted below are items that we had to buy because a late order was not possible because of the obsolescence of the technology (ASICS) or non availability of the producer (Honeycomb plates,I beams) or of the assembling factory (Al plates and I-Beams).

For the spare detectors the value is for material only (Honeycomb plates , Aluminium plates,I-beams et cetera ,part of them are already committed and part we should order this year in order to have them in Dubna and Protvino before the end of the assembly) Electronics and boards are included in ASICs and Boards.
ASICS Chips include the MADs (front end amplifiers),the BTIs ,the TRACOs (already payed).
I included also an approximate amount of money for the spares TDCs that will go in production in The HVB are the spares of High Voltage Distribution Boards ,currently in production to be concluded in 2004 (the cost is the cost of the material only).
Le percentuali indicate per gli
ASICS sono la parte eccedente
quanto ritenuto necessario
durante la costruzione.
Following an agreement taken in the RRB of April 2002 ( Scrutiny Group Report CERN-RRB ) “spares are often to be ordered in advance,with the main procurement. In the case of ATLAS provision to buy spares is made by borrowing from the future etc…” We propose to move this money on the M&O B part as done for Tracker and ECAL. The same request will be done by our Spanish and German colleagues to their Agencies.
