					     EMCal Cabling Update
• We are requested to prepare all cables to CalFrame, and on
  CalFrame, prior to installation of CalFrame in ALICE (June).
• We have ordered ~all cables and connectors necessary for this
  purpose:
   – ~12000 CHF for cables and connectors
   – ~16000+3780 CHF for 95mm2 LV cables
   – ~18500 CHF for cable trays and LV distribution panels
• We have ~500 cables in ALICE DCDB that need to be
  made/labeled/installed in April/May.
• When complete the SM installation becomes “easy”. All remaining
  service connections are at SM Electronics crate with the exception
  of LED fibers which must be run from SM to LED drivers.
• Details of Cable Specifications and Orders can be seen at:

                         Details of Cable Plant

• ELMB (=Slow control - Temp monitoring):
   – CAN Bus cable from CR3 to CalFrame by DCS group
   – CAN Bus cable from A to C side and between ELMB mother boards by
     DCS group
   – 4 ELMB mother boards with ADC chips provided by DCS group

   – 12 34-wire flat ribbon cables with connectors prepared by EMCal group.
     (est. ~1 day)
• Installation
   – Installation of all cables (except LV) on CalFrame by CalFrame by
     EMCal group. Working at heights (~10m). (Est. ~1 week)
• Database
   – All Details have been developed in spreadsheets (see web link) which
     have been “cleansed” for automatic input to DCDB where cables and
     node-names are defined.
   – Used to produce cable labels
   – Used to schedule cable installations by CERN group

                        Details of Cable Plant

• Installation plan
   – All cables (some exceptions) are at CERN.
   – All connectors (some exceptions) are ordered and expected to
     be at CERN within the next week or so.
   – Propose that someone with technical expertise to make cables
     come to CERN for few days and attempt to make at least one of
     each cable/connector type to insure that all parts are correct and
     to estimate time necessary to make all cables.
   – Then schedule one or two later visits to make all cables, and
     then to install all cables. Installation must wait until CalFrame is
     at CERN, weight test is performed, and cable trays are installed.
   – Cable installation by EMCal can probably be done in parallel to
     LV cable installation since in different cable trays and can work
     on A or C side.

                      Temperature Readout

• By fiat, we’ve decided to use one 16-Channel ADC
  ELMB group per SM. One 34-wire flat ribbon cable.
• Two types of temperature sensors - 2-wire and 4-wire
  that require 1 or 2 ADC channels each, respectively. The
  4-wire allows a reference loop subtraction for better
  stability/reliability.
• Propose that the ELMB for each SM be configured with 2
  4-wire sensors and 12 2-wire sensors.
• Use 2 2-wire sensors in opposite corners of FEE crate
• Use 10 2-wire sensors to distribute across SM to
  measure temperature field.
• Use 2 4-wire sensors on SM to insure stability of overall
  temperature scale.

                               EMCal FEE Crate

• Electronic:
   – Once T-card is finalized need to layout IPCB and GTL bus (A
     and B) for EMCal FEE card spacing - Nantes?
   – Should produce all IPCBs and GTL buses ASAP. Should use
     new T-cards, IPCB, and GTL for next test beam. Also use them
     for APD/FEE test stations.
• Mechanical:
   – Need final design of FEE crate structure and enclosure/door
   – Cooling manifold and cooling plates
   – IPCB support, FEE card rails.

                             SMs on opposite sides then as well to order

                    - 8 channels/module (3.7kCHF each).
                  • Require one HV channel per FEE crate - 4 per
                    SM for total of 44 HV channels: Requires 6 ISEG
                    modules (48 HV channels).
                  • Should purchase crate + 1 module soon, i.e for
                    test beam (~9kCHF)
                  • Use same HV supply for LED driver
                  • Two bulk HV cables - one per side. CERN stock
                    56-wire = 28 HV per side. ERNI connector.
