Status of MB4 Production Preparation
2nd
iron cast table will be delivered in Sette Comuni on 17th June.
Delivered and aligned
Work 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 September
Plotters: 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. BUT
Mimmo: 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 Preparation
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 Torino
ready to be machined.
Done
Frame 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

• 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

(42 +?)
YB-1 November 2004 (begin)
 YB -1 YB -2 April-June 2005
(68 - ?)

• for Alignment/Magnet Test
18
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 chambers
from CIEMAT to CERN
April 2002
Currently 12 ch. From CIEMAT
stored at ISR
LNL and Aachen will ship 8 ch.
each in Oct./Nov. 2002.
Delay due to the gluing of RPC
Pads at home.
23
Chamber Preparation
• DT and RPC chambers are
sent to the ISR from the
assembly centers fully tested
• Acceptance tests: HV, Leakrate,noise, cosmics
• DT alignment calibration
• DT cabling+services
• DT assembly with RPCs
• Storage in transport fixture
24
Chambers stored and
tested at ISR Hall
25
ISR:
Standard work:
accept/store chambers
gas tightness/HV/noise test
repair
alignment
long term HV test (1~3 months)
insert/test minicrates
cooling test
couple to RPC
(cooling test)
Non standard :
(from now to July 03)
glue RPC Pads to CIEMAT ch.
insert and finish HV cables
(4 HV connectors/DT in ~ 80 ch at 4ch/week
then done in the labs)
complete gas and cooling piping
(~ 60 ch. at 3 ch/day then done in the labs)

2 persone X 6 mesi = 12 m/u
2 persone X 6 mesi = 12 m/u
2 persone X 2 mesi = 4 m/u
L’idea e’ di avere 4~ persone per I due mesi di installazione
E di due persone per 8 mesi per attivita’ di completamento
Ricezione/stoccaggio e test . Altre 3 persone saranno inviate
Da Aachen e CIEMAT.
Inoltre Pd e Bo chiedono di mantenere un fisico per 12 mesi
Complessivamente e che questa persona sia conteggiata al di
fuori dei 2.5 m/fte usuali.
E’ chiaro che RPC devono essere coinvolti nell’operazione
E mantenere anch’essi qualcuno in permanenza,quando e in
Quanti dipendera’ dagli sviluppi della loro costruzione

3) electronics:
electronics is sitting on the chambers
in each chamber of one CMS sector :
in the gas volume : F-End chips/boards & HV boards
32 F-End chips (2 Boards) feed:
in the Minicrates :
4~6 ROB (Read Out Board) 128 wires
4 TDC (any of them can act as Master)
=> precise coordinates
4~6TRB PHI(Trigger Board) 128 wires
32 BTI,4 TRACO,1 TSServer
2 TRB THETA housing BTIs only
=>2 best MU in the Board (64 cm)
ONE TS Board
houses the TSMaster
(two parts,any can act as master)
=> 2 best MU in the chamber

Further Installation Tests

•Installation of a minicrate ( trigger,readout and control electronics) on a
chamber already installed.

MINICRATE
37
HPTDC/Cern/Mic was resubmitted in September to include small corrections
mainly to the Voltage regulator .
Using the HPTDC from the previous engineering run CIEMAT produced several
Rout Boards

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.

new PCB design finished, 20 PCB 2nd half October
5 TRBs end November for first MINICRATE
two minicr. available for test beam of May 2003
Production plan for TRB:
4 months for material procurement
1 month 50 samples
1 month approval
Preserie 200 after 3 months
In June/July 2003
200~250 TRB could be available to begin the “mass prod.” of Minicrates
(200 TRB = ~ 40 Minicrates ,one wheel in SX ,but assembly rate of minicrates
still unknown and some delay in the production of TRB or BTI mod. is well
possible) . The Minicrates need also Control&Server Board.
42
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 to
house some buffers and to accept new connectors. The design
of 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 must
Wait 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. Test
at the end of 2002
