On detector region : AFEC Ø Ten types, 1 for each CSC Ø Need 70 pcs (including spares) Ø Produced 25 pcs – 15 soldered on CSC and installed on T 1 ¼. – 10 = 1 spare for each type. Ø Remainder 45 pcs. – Need two months (pcb + components) Ø Set-up @ bld. 188 measured a huge amount of noise – New AFEC worse than the old one tested at H 8. – Long investigation reason was the wrong AFEC input filter capacitor value. Mounted 2. 7 n. F while 2. 7 p. F was required. – Capacitors replacement in progress (~4000). • Now the T 1 anodes noise value is ~10 VFAT thr. Ø Tests in progress (now @ Genoa lab. ) Saverio MINUTOLI TOTEM Electronics W. G. , 9 December 2008 4

On detector region : CFEC Ø Need 180 pcs (including spares) Ø Produced 45 pcs – 39 installed on T 1 ¼. – 6 spares. Ø Remainder 135 pcs. – Need two months (pcb + components) Ø 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 T 1 cathodes noise value is ~17 VFAT thr. Ø Tests in progress (now @ Genoa lab. ) Saverio MINUTOLI TOTEM Electronics W. G. , 9 December 2008 6

Local detector region : ROC Ø Need 40 pcs (including spares) Ø ROC v 1. functionalities tested. – All major blocks OK Ø Produced 12 pcs – BC 0 transmission line new layout v. 2 – 2 ROC v. 1 Ø ROC v 2. Tests in progress (now @ – 10 ROC v. 2 Genoa lab. ) Ø Remainder 30 pcs. – Need two months (pcb + components) Saverio MINUTOLI TOTEM Electronics W. G. , 9 December 2008 7

Conclusions Ø 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 T 1 internal cabling (slide #11). Ø Cables: – External services from platform to T 1 6 th frame. Need cables procurement. (? ? ? ) – Internal Need cables procurement (Genoa) Ø Fibers: – External from T 2 Rack to T 1 6 th frame (CERN) – Internal short fan-out, see slide #11 (CERN). Ø 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).
