amedeo.staiano@to.infn.it

2nd iron cast table will be delivered in Sette Comuni on 17th June.Delivered and alignedWork area enlargement approved by director, installation starts at the beginning of July. Time

estimated for completion of infrastructure work (crane extension, air conditioning system upgrade, final cleaning) 2 months.Begin work end July, expected to be finished by end SeptemberPlotters: driver cabinets cabled and ready. Only missing part are the beam supports. Mimmo,

back from China for MB4 support commissioning, will finish the drawings in July. Parts will be manufactured in September. BUTMimmo: designed details for MB4 supports insertion done in July but was not planned; presently working on gas system (first 2 weeks of Sept.) NOT working on MB4. Qutlook: will have start contract w/ integration on Nov. 1st and work on beam supports until end of Sept.Will start working on I-beams tool drawings in Oct.All other parts have been delivered. Plotter beams ready to be sent to CINEL for milling.

Done in July.Glueing machine under test to check functionality for 15mt long pipes and possibility of glue

dispenser splitting. One driver lost during set-up, replacement ordered.Tooling: I-beam tooling to be designed starting from September. See above

Status of MB4 Production PreparationSez. di Torino

amedeo.staiano@to.infn.it

MB4 HV and FE frame cabling: 2 electronicians will start to work with us after 8th july, they will go to Legnaro on 16 July to learn how to start SL frame cabling work. Frames already in Torinoready to be machined. DoneFrame cabling will start beginning of September.Preparing area, tools.Silvia collecting docs etc., waiting for material (3 profiles) from CINEL, Madrid (1, end of September);Electronicians will go to Padova, collect cables, connectors etc., more training. Start work in Torino.Schedule: within the present schedule we are expected to provide a first SL by the end of the year. Two months delay in production preparation due to integration work on HV cable length and MB4 support commissioning test in Bejing (Mimmo) -> no MB4 SL before the end of the year. CONFIRMED

Chamber Installation Scenario• in v33 42 ch/wheel in SX in v 32 38 ch./wheel in SX

•Installation crew of 4 technicians from home Institutions plus crane operators

• Installation rate of one chamber/day at start-up

• plateau at 8 chambers/week

• One wheel (10 Sectors) = 42 Chambers in 5 weeks

• YB 0 & YB-1,Sectors 8-9 September-December 2003 (42 + 8 ch.)

YB+2 January-February 2004 (42 ch.)

YB-2 Sectors 8-9 March 2004 ( 8 ch.)

YB+1 September 2004 YB-1 November 2004 (begin) (42 +?)

YB -1 YB -2 April-June 2005 (68 - ?)

• 10 Sectors (40 Chambers) are installed in UX5 starting September 2005 (~10 weeks to complete).

• for Alignment/Magnet Test

19

Installation Tools

Some tooling is still needed for full scale installation:• Transport frames for DT+RPC (CIEMAT). • Ancillary tools for cradle rotation (Padova).• Construction of a larger cradle for MB4.

In addition we will rely on existing SX5 equipment:• Cherry pickers, movable platforms …• Refurbished L3 scissor lift.

Tooling costs are within cost book estimates.

Last shipment of chambersfrom CIEMAT to CERN

April 2002

Currently 12 ch. From CIEMATstored at ISRLNL and Aachen will ship 8 ch.each in Oct./Nov. 2002. Delay due to the gluing of RPCPads at home.

24

Chamber Preparation• DT and RPC chambers are

sent to the ISR from the assembly centers fully tested

• Acceptance tests: HV, Leak-rate,noise, cosmics

• DT alignment calibration• DT cabling+services• DT assembly with RPCs• Storage in transport fixture

25

Chambers stored andtested at ISR Hall

26

ISR:

Standard work: accept/store chambersgas tightness/HV/noise testrepair alignmentlong term HV test (1~3 months)insert/test minicratescooling testcouple to RPC(cooling test)

Non standard : glue RPC Pads to CIEMAT ch.(from now to July 03) insert and finish HV cables

(4 HV connectors/DT in ~ 80 ch at 4ch/weekthen done in the labs)complete gas and cooling piping(~ 60 ch. at 3 ch/day then done in the labs)

27

Presenze gruppi DT INFN ad ISR durante 2003

Bologna 2 persone X 6 mesi = 12 m/u Padova 2 persone X 6 mesi = 12 m/uTorino 2 persone X 2 mesi = 4 m/u

L’idea e’ di avere 4~ persone per I due mesi di installazioneE di due persone per 8 mesi per attivita’ di completamentoRicezione/stoccaggio e test . Altre 3 persone saranno inviateDa Aachen e CIEMAT.

Inoltre Pd e Bo chiedono di mantenere un fisico per 12 mesiComplessivamente e che questa persona sia conteggiata al di fuori dei 2.5 m/fte usuali.

E’ chiaro che RPC devono essere coinvolti nell’operazioneE mantenere anch’essi qualcuno in permanenza,quando e in Quanti dipendera’ dagli sviluppi della loro costruzione

28

1 - Transport to CERN2 - Test at ISR3 - Alignment calibration 4 - Installation of RPC(s)5 - Transport to P56 - Test at P57 - Insertion in YB8 - Test in YB (gas,cooling,HV)

Several ancillary tools are neededthat are under design or construction

SCHEMATIC OF A MINICRATE

36

Further Installation Tests

•Sector Test: Install MB1, MB2, MB3 complete with cables and services.•Installation of a minicrate ( trigger,readout and control electronics) on a chamber already installed.

MB2 minicrate prototype with readout electronics under test in CIEMAT

37

MINICRATE

38

• Madrid reports there are enough ROB-128 (with HPTDC v 1.1) to equip two full minicrates. • Final ROB-128 design will be verified in short time and 10 more boards will be available. Assembly of boards with final HPTDC will not start until late this year. • The company designing ROS-8 prototype PCB has reported routing problems and is delayed. The final board for MC operation is expected by September. Preliminary operation has been described.• Two MB1 minicrate mechanics are ready at the moment, two MB2 are in process.

HPTDC/Cern/Mic was resubmitted in September to include small correctionsmainly to the Voltage regulator .Using the HPTDC from the previous engineering run CIEMAT produced severalRout Boards

Production plan for TRB:4 months for material procurement1 month 50 samples 1 month approvalPreserie 200 after 3 months

In June/July 2003200~250 TRB could be available to begin the “mass prod.” of Minicrates(200 TRB = ~ 40 Minicrates ,one wheel in SX ,but assembly rate of minicratesstill unknown and some delay in the production of TRB or BTI mod. is well possible) . The Minicrates need also Control&Server Board.

43

Control and server boards

They sit in the MINICRATES of which they control all the functionalities

These are two boards :the server is piggy backed on the Control.

The Control board was slightly modified after the system test tohouse some buffers and to accept new connectors. The designof the new PCB is going on and will be finished by end september.

The Server part is complete and ready to be produced.The funding for both is allocated in the 2002 /2003 And first orders will be placed soon. However the Control mustWait for the final TTC/RX . We hope to have by october the Pin out in order to complete the PCB.A proto with the old scheme is in any case needed for the MINIC. Testat the end of 2002
