  3. ECAL numbering scheme • CMS-note 2005/021 “CMS ECAL Barrel channel numbering”. • New numbering of SMs of EB (no change of the rest). • Numbering of trigger sectors in EE. • Numbering of data sectors in EE. • Scheme for both hardware and software. • Scheme has to be compliant with official CMS numbering scheme and the standard trigger system numbering. • ULR crate organization is organized as CMS trigger system demands. • In all sub-detectors the numbers are identical in each Φ-trigger slice. • After discussions with a lot of people new scheme has been accepted by the ECAL management. 02/11/2005 3 Wolfgang Funk - CERN CMS

  13. X L-2 L-1 Laser distribution system general • Laser station is connected via switch to mother fibers. • Switch has to be at least (2x36 + 4x4) = 88-way. Maybe 92-way? • Each mother fiber (coming from the laser switch in laser • barrack) has one Level-2 fanout. • Each Level-2 fanout has 7 fibers going out towards one • Level-1 fanout, where normally 5 are installed. • Each Level-1 fanout has 240 fibers going out towards the Xtals, • where at least 200 working fibers have to be available for Xtals. • Each Level-2 fanout has one fiber to a PN diode in a FEM. • Each Level-1 fanout has one fiber to a PN diode in a FEM. • Each FEM has 2 PN diode either for Level-1 or Level-2 (not • mixed). • Each FEM has 2 read-out cables to (Double) MEM-box. 20/09/2005 2 Wolfgang Funk - CERN CMS

  14. X L-2 L-1 Laser distribution system EE specific • 6 mother fibers per Dee are installed in pt5. Need spares! • 4 Level-2 fanouts per Dee are foreseen. • 20 Level-1 fanouts per Dee are foreseen. • If possible, each fiber connected to one Level-1 should get • similar radiation dose. • 12 FEMs (24 PN diodes) per Dee are foreseen. • Power cables for 12 FEMs are installed in pt5. • 24 read-out cables per Dee from FEMs to Double MEM (has • 24 ADCs) are installed in pt5. • Double MEM reads 2 Quadrant (≡ 2 SMs) 20/09/2005 3 Wolfgang Funk - CERN CMS

  15. X L-2 L-1 Data sector/DCC architecture EE specific • Per Dee there are 4 ½ data sectors. • Each data sector has one specific DCC in the ULR. • Laser trigger information is sent to DCCs, to determine which • DCC is read out. • All Xtals in this data sector are then read out. • To read out several data sectors, a special bit pattern is used, • special firmware would need to be developed. 20/09/2005 4 Wolfgang Funk - CERN CMS
