3 Saverio MINUTOLITOTEM Electronics W.G., 9 December 20083 VFAT strip hybrids ‣ Request 550 pcs. ‣ Delivered 193 pcs. ‣ 129 pcs good. ‣ 64 pcs bad. ‣ Remainder 357 pcs: ‣ ( Pcb + passive components + connectors ) (by Cern) ‣ Chip gluing (@ Cern by Genoa tech.) ‣ ( Chip bonding + hybrid tests ) (by Genoa) Trigger VFAT mezzanine ‣ Request 40 pcs. ‣ Delivered 1 pc, good (by Cern) ‣ Remainder 39 pcs (by Cern) Need 2÷3 months

4 Saverio MINUTOLITOTEM Electronics W.G., 9 December 20084  Ten types, 1 for each CSC  Need 70 pcs (including spares)  Produced 25 pcs –15 soldered on CSC and installed on T1 ¼. –10 = 1 spare for each type.  Remainder 45 pcs. –Need two months (pcb + components)  Set-up @ bld. 188 measured a huge amount of noise –New AFEC worse than the old one tested at H8. –Long investigation  reason was the wrong AFEC input filter capacitor value. Mounted 2.7nF while 2.7pF was required. –Capacitors replacement in progress (~4000). Now the T1 anodes noise value is ~10 VFAT thr.  Tests in progress (now @ Genoa lab.) On detector region : AFEC

6 Saverio MINUTOLITOTEM Electronics W.G., 9 December 20086  Need 180 pcs (including spares)  Produced 45 pcs –39 installed on T1 ¼. –6 spares.  Remainder 135 pcs. –Need two months (pcb + components)  Noise investigation has emphasized that the VFAT is sensitive to the position of the pcb hybrid ground connection. Few centimeters are enough to measure differences (Blue is better than red connection). Now the T1 cathodes noise value is ~17 VFAT thr.  Tests in progress (now @ Genoa lab.) On detector region : CFEC

7 Saverio MINUTOLITOTEM Electronics W.G., 9 December 20087 Local detector region : ROC  Need 40 pcs (including spares)  Produced 12 pcs –2 ROC v.1 –10 ROC v.2  Remainder 30 pcs. –Need two months (pcb + components)  ROC v1. functionalities tested. –All major blocks  OK –BC0 transmission line  new layout v.2  ROC v2. Tests in progress (now @ Genoa lab.)

10 Saverio MINUTOLITOTEM Electronics W.G., 9 December 200810 ‣ Cables from detector (6th frame) to mini-rack on platform: -intermediate patch panel not required any more; -will need to add cables for position and B-field sensors (Dmitry). Cabling on YE3 - Position and B-field sensors cables

11 Saverio MINUTOLITOTEM Electronics W.G., 9 December 200811 L1=50cm L2=12m Optic Fibers Patch Panel 8 MPO T2 Rack GOL/DOHM MPO in line adapter Fan-out Box on T1 6th frame Multi ribbon cable (8x12) Ribbon fiber cable (12x1) Single fiber SMU in line adapter 12 8 L3=2.3m L4=3m L6=2m L5=2m T1 internal distribution Platform Side Cable Tray sideT1 quarter side #2 #1 #3 #4 T1 ¼ Optic Distribution Scheme NEED SOON T1 optic fibers distribution.

13 Saverio MINUTOLITOTEM Electronics W.G., 9 December 200813 AFEC CFEC ROC Gas lines CFEC cooling lines Half-arm mounting test  Complete assembly of one half-arm at bldg. 188: –Very useful to check everything fits and solve all small problems.

14 Saverio MINUTOLITOTEM Electronics W.G., 9 December 200814 Conclusions  To obtain from CERN: –357 Hybrids (slide #3) They need chip gluing, bonding and testing (by Genoa) –39 Trigger VFAT Mezzanine –All the Counting room electronics (slide #9) –16 Short ribbon fiber cable for T1 internal cabling (slide #11).  Cables: –External  services from platform to T1 6 th frame. Need cables procurement. (???) –Internal  Need cables procurement (Genoa)  Fibers: –External  from T2 Rack to T1 6 th frame (CERN) –Internal  short fan-out, see slide #11 (CERN).  On detector and local detector cards: –AFEC: lab. final test, cosmics tests, end production (Genoa) (slide #4). –CFEC: lab. final test, cosmics tests, end production (Genoa) (slide #6). –ROC: lab. final test, DAQ tests, end production (Genoa) (slide #7).
