ROC (1)
Some delays due to CERN custom components procurement. Needed to avoid wrong components packages association.
Several features implemented: DOHM and CCUM emulation. DOHM I2C lines handling (follow the CCUM-SCR redundancy
scheme). Trigger VFAT Mezzanine GOHs mezzanines input pattern generator. Several Data GOH DAV sources available. Several Trigger GOHs DAV sources (BC0, Static, Timed by CCUM) Foreseen a SPY Mezzanine based on T1 Digital Mezzanine.
The layout is in progress. 5 PCB ready ½ Dec.07 3 Circuits mounted and tested ½ Jan.08 PCBs mass production ½ Feb. 08 Full ROCs ready within March 08.

VFAT hybrids
Hybrids production (PCBs and components mounting) at CERN. High density input connectors available from T1.
Bonding may be made in Genoa. Needs agreement with the people in Genoa lab. Needs to know all the rules and material used by the CERN
bonding lab. Needs some VFAT dummy chips in order to test all the procedures. Could be useful a training period at CERN of our bonding
technician. Validation of the first hybrids in accord with the CERN people
(W.S.- P.A.). The installation of 1 arm (30 CSCs) in March 08 involve 140 VFAT
hybrids. This number is equivalent to the full T1 anode VFATS hybrids
production including spares. In this installation 60 will be dedicates for the anodes and 80 for
the cathodes (CFEC VFAT only based). VFAT hybrids schedule is CERN production dependent…

T1 Trigger Mezzanine
T1 detector have 15 trigger fibers per each ¼ while each OptoRx mezzanine accept up to 12 fibers.
In order to merge and manipulate with a dedicate algorithm all the trigger bits (30 fibers in total), we will need the custom TTM mezzanine to add to the Trigger TOT-FED.
The trigger system is not completely fixed, need some more iterations within the trigger group.
TTM not needed at the beginning (March 08). Expected to be available in June 08.

16 channels preamplifier (1)
This small boards use the same FE preamplifier device integrated inside the VFAT chip (see Jan Kaplon).
Needed for final studies on T1 CSC detector. Layout in progress. Some PCBs ready and mounted 2nd w/Dec.07 End tests and decision on the AFEC and CFEC
passives networks components within Dec. 07

Low Voltage and High Voltage components.
Placed order at CERN for 5 WIENER fully equipped MARATON low voltages system. Two simple VME crates are also purchased for
the MARATON remote control cards. Delivery expected within March 2008.
Almost placed an order to CAEN for 6 HV modules A1550P, and one mainframe SY1527. Delivery expected March/April 2008.

Patch panels
Hosted on the platform: Low voltage it could simplify the connections with the
WIENER. (not needed at the beginning) High Voltage to be done, (not needed at the
beginning) but ok for March 08. Connector procurement done.
Hosted on the 6th T1 Frame: Low voltage prototype almost ready, ok March 08. High Voltage all produced, one prototype almost
ready, ok March 08. Optic fiber to be done, need a fiber cable fan-out and
MPO connector for the dimensioning of the box (see W.S.).
