GRI 21-09-05 M. Diemoz - INFN Roma
Cristalli : BTCP
• Problema di qualita' messo in evidenza a giugno (rad hardness).
Rigettato un intero Batch, giro di vite sul QC (irraggiamenti).
• Conclusi contratti precedenti, inclusi 500 xl rimpiazzo.
• Nuovo contratto 18K Barrel + 4250 EE (+ contributo in-kind EE)
firmato con Russian Electronika a fine Giugno. Partenza a Settembre
per 1100xl/mese + incentivo quantita' eccedente (ad oggi la frequenza
media di consegna e' stata di 1150xl/mese)
• Opzione per una ulteriore produzione prevista nel contratto
• Recente visita alla fabbrica positiva, qualita' cristalli tornata quasi ok
(da tenere comunque sempre sotto controllo).

Cristalli: SIC
• Ricevuti pre-serie 350 EE• Ricevuta pre-serie of 100 EB • Raggiunto accordo per l'irraggiamento da parte di SIC di tutti i cristalli
con rilascio di certificato. Protocollo tecnico definito dopo un'intensa attivita' incrociata di irraggiamento e dosimetria.
• Formalmente firmato contratto 2700 EB + 2950 EE• Produzione in aumento (verso 150 xl/mese)• Problema permanente
– Pt import/export (si importa ma non è chiaro se si esporta...)
– Se non si risolve SIC produrra' 1300 EB

Cooling integration problems (1)
• Early May, we noticed root porosity (= oxidation) on some of the welds on the internal cooling manifolds (5 SM già prodotti)
• This was traced down to insufficient neutral gas inertion inside the tubes during welding.– Could be easily fixed by the producers
• However, this triggered further investigations of the welds quality (by Xrays and endoscopy).– Lack of full penetration observed on some of the manifold welds– Full penetration of the weld: this is required by CERN for high
pressure/velocity circuitry, – Welding faults ( cracks and craters) : such fault cannot be tolerated as
they can evolve in time and lead to leaks. • Cooling integration (and therefore electronics integration) is stalled. Already
assembled SMs (4) will have to be retro-fitted.

Cooling integration problems (2)
• Considerable effort during the Summer to fix the problem at the factory
– Frequent visits of CERN welders
– New TIG welding equipment bought / optimization of pipe thickness
– Not succeeded to get 100% reliability on welds
• Mid August, it was decided to in-source the welding work at CERN, under responsibility of TS division
– modification of collector shape allowing Electron Beam welding of the small pipes from inside.
– Design modification quickly done (early September)
– Small scale tests successful
– Complete manifold being welded before end of september
• Mini-review to be held by A.H. on September 29th
• Schedule:
– 1 set of 4 cooling blocks by Mid October; then 4 sets per month
– Electronics integration being upgraded to sustain the same rhythm.

Cooling
• Una stima precisa del costo ci sarà una volta dimostrata la validità dellasoluzione tecnica prevista• Alcuni costi (nuovo tubo collettore) sono già chiari e dovranno essereaffrontati a breve• Il costo principale è relativo al manpower (CERN) necessario a gestire il processo di saldatura ad electron beam • Il management di ECAL è in completo accordo sul reperire questi fondicon la collaborazione di più istituti (CERN, INFN, UK)

Integrazione
Il problema del cooling ha bloccato l’integrazione dei Super Moduli
(prevista iniziare a luglio)
• Cambio di strategia: l’assemblaggio di molte componenti del SM previsto in parallelo al montaggio stesso. Si stanno creando dei buffer di parti di questo tipo in modo da rapidizzare l’integrazione finale.
• Si sta approntando una quarta linea per recuperare l’inevitabile ritardo.• Se la produzione del sistema di raffreddamento partirà a novembre
come possibile e verrà mantenuto il ritmo di 4SM/mese riusciremo a tenere la schedula

Integration Area at B867
We have a space for integration where we can work on 3 integration line in parallel.
The integration is under the responsability of W.Lustermann of ETH Zurich. The coordinators of the 3 integration lines are: D.Bailleux (Minnesota Univ.), C.Biino (INFN Torino), L.Djambazov (ETH Zurich)

VFE/LVR Front Cover
• Mounting of the front covers (for VFE/LVR) done at CERN: deposition of gap pad paste on each component, 12 screws to fix the cover and 5 gap pads glued on the cover. Up to now we have prepared about 4000 VFE, and 4800 VFE are waiting for the front cover delivery.

Low Voltage Distribution (LVD)
Each one of the 17 LVD in a SM has cables of different length since the cables are very stiff and there is not space to store the eventual extra cable length . At the moment we are adding a protection resistence and we have nearlyfinished the assembly of all 612 pieces.

Assembly and Testing
During the installation of the first 3 SM there has been a lot of learning on defining and optimizing the installation procedure and testing.
Two completely installed SM are available at the moment as test benches for DAQ (et al.) studies :SM11 in B867, SM5 in H4
