  1. TOTEM ELECTRONICSSTATUS Walter Snoeys Collaboration meeting 25/2/2004

  2. 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 (and T2) Electronics Collaboration meeting 25/2/2004

  3. 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.

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 Collaboration meeting 25/2/2004

  4. 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 + ??
