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.

Laser distribution system

L-2 L-1
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.

• 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)

Data sector/DCC architecture
EE specific
L-2
L-1
X
• 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.
