Saverio MINUTOLITOTEM Electronics W.G., 9 December 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

Saverio MINUTOLITOTEM Electronics W.G., 9 December  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)  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 Genoa lab.) On detector region : AFEC

Saverio MINUTOLITOTEM Electronics W.G., 9 December  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 Genoa lab.) On detector region : CFEC

Saverio MINUTOLITOTEM Electronics W.G., 9 December 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 Genoa lab.)

Saverio MINUTOLITOTEM Electronics W.G., 9 December 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).
