Roman Pot (and T2) Electronics• CMS based: APV + optical links for data, trigger and control• Trigger electronics TOTEM specific:

– New trigger chip developed by CERN-MIC (VFAT) provides:• 128 channels digital tracking data + 128 deep pipeline memory• Serial tracking data output upon trigger signal• 8-10 trigger outputs (fast or of group of channels)

– On trigger plane 4 APV’s replaced by 4 VFAT’s:• Trigger outputs grouped over 1 optical serial link/plane• Tracking data sent over analog APV link

– TOTEM trigger box:• Receives and synchronizes optical trigger signals• Performs trigger generation• Sends trigger to CMS and/or TOTEM

• Detector geometry TOTEM specific:– Geometrical redesign of CMS electronics close to detectors– Counting room electronics for CMS part identical



• Roman Pot electronics– Totem APV hybrid Manu Sanchez EST design 1st version ok– Totemflex “ 2 wks– Totem APV testcard (arcs & st cms compatible) “ 2 wks– Production to be organized asap Rui De Oliveira EST

– VFAT Testcard J. Kaplon + MS EST 2 wks– Production to be organized asap Rui De Oliveira – VFAT Testing Shayar + Roberto Dinapoli after testcard– Totem VFAT hybrid Roberto Dinapoli + MS EST design in April, production

go ahead after 1st VFAT measurements

– Roman Pot Motherboard Lyon input for schematic CMS part Need to define optical Some input on optical link (A. Kok) serial link (800MHz vs 1.6

GHz) + decision on VFAT readout

– SPS cables and patch panels Anne-Laure Perrot + Daniela Macina cables ordered + installed, patch panels in course of definition

– SPS trigger signals Marco Bozzo people contacted to obtain clock and trigger signals from Beam Monitor

– Cooling electronics F. Haug + AL Perrot (patch p) Definition in progress– Roman Pot control (motor) M. Oriunno + AL Perrot(“) Use hardware chosen by

machine people– Roman Pot T & P measurement M. Oriunno(P)+ E. Noschis(T)+ AL Perrot (patch P) Nat. Instr. based for T (Elias),

P in progress– Roman Pot High Voltage G. Ruggiero Caen based, interface

available, needs some work– Detector design G. Ruggiero + E. Noschis + V. Eremin + C. Kenney 3D planar in processing, end

of March, edgeless design 2 wks

– Optohybrids A. Kok + group F. Vasey testing & qualifying, GOL link to be defined further

– FEC electronics Mic Group + Brunel qualifying boards– FED electronics Mic Group + Brunel + RAL– SPS + X5 trigger box ?? Optical link dependent, needs

deserializer + then some concidence

– Alignment and mounting procedure definition input from Sherwood Parker, Marco O come close to final solution G. Ruggiero, M. Deile Roman Pot and X5 compatible



Electronics status• T2 electronics– X5 Test Compass (APV) based Marco Bozzo + ?? Design is there, some

production necessary, will watch geometrical compatibility

with final system– Final system APV and VFAT Marco Bozzo + ?? Similar to (positive answer from Compass:

• outputs (fast or of group of channels)• T2 electronics

TOTEMTRACK

This is the card inside the Roman Pot which incorporates the CMS hybrid with 4 APV chips

Interconnect to the outside 40 connections at low voltage for hybrid

itself 4 connections for Pt-100 2 (Gnd and high voltage) connection

=> low voltage ZIF kapton connector 51 pin for low voltage and Pt-100

=> high voltage minimum two wires Need good thermal connection to frame (TOP

and Bottom), needs Cu feedthroughs

TOTEMFLEX

This is the kapton which needs to connect the totemtrack and totemtrig cards to the motherboard

44 lines Interconnect + a mass plane on one side for the LVDS connections

Need variable length because of pot geometry Need two version one for backward and one

for forward connection. Needs to be rigidified at the end.
