Production planned from Oct 03 to March 04 MAB production - Prototype (from INEGI) arrived end on June During the summer: Survey and PG measurements of structure stability under loads Production planned from Oct 03 to March 04 Results of 49 days test: (+5.2 Kg ,gravity load): Out of plane 20~ 50 mu (11 points) Vertical 50 mu (7 points) Temp: 20 deg +- 1 Hum. : 70 – 45% Mabs will be individually Calibrated on a special bench 22/04/2019

The three sites are producing at the rate of 18 ~ 20 chs./ year TORINO: first table commissioning begin end of March ,first SL (Amedeo ?) 5 chambers (10 SLs) are needed before end of 2003. The photogrammetry and calibration procedure of the Alignment bench is concluded. The first chamber is going to be measured from 17 ~ 24 of March . The test should last one week ,then 2~ 3 chambers/week First installation test (MB2) done in August 02,test of installation of 1 MB1 and 1 MB3 in sector 5 (no RPC) done in December Next Install. Test week of May 5th 22/04/2019

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 Beam in May 22/04/2019

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 2004 100 Trigger Boards PHI 40 Tr.b. THETA This imply 1120 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 22/04/2019

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

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. 22/04/2019

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).   SPARE Detect(meccanica). 19x20 KChF 380 ASICS CHIPS (15 ~ 30%) 450 FE BOARDS 10% 200 HVB 15% 102 TRB (trigger boards) 10% 62 ROB (read out boards) 10% 50 CCB/SB(control/server boards) 10% 80 STAND EL. (PS,balconies) 5% 160 Total 1212 112 160 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 2003. 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-2002-036) “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. 22/04/2019
