n. SQP’s DBM Interfaces Meeting D. Giugni / INFN Milano D. Giugni DBM Interfaces Meeting 2011 -09 -28 1

Project framework • • • The 4 DBM telescopes (per side) are hold by the BPSS (Pixel Beam Pipe Services Support) They are supported by the “cruciform” at about Z=800 mm The services, both cooling and electrical, are routed along ONE n. SQP (the C 34). D. Giugni n. SQP’s C 34 n. SQP Ve Di rtic rec al tio n DBM Interfaces Meeting 2011 -09 -28 BPSS 2

Cooling • • • n. SQP’s 1 Pixel loop = 220 W @ -25 C Max Press = 13 bara Evaporation temperature -15 C<T<+20 C PP 0 D. Giugni PP 1 DBM Interfaces Meeting 2011 -09 -28 3

Electrical Services n. SQP’s • DBM looks like an IBL half stave with 4 x 3=12 FE chips instead 16. • Both power and readout will belong to IBL readout – Power lines and DCS reach the IBL AXON Connector on the IDEP – The signal lines (DTO, CLK and CMD) reach the IBL optobox where a dedicated Optoboard reads-out the signals. Since an IBL Opto. Board can handle 16 FE chips, the 16 -12=4 extras can be used to extract the trigger. D. Giugni DBM Interfaces Meeting 2011 -09 -28 4

Scopes and goals of the meeting • n. SQP’s Main scope is to define the interfaces: – Connector type, number and position next to the DBM telescopes – Position of the fitting for the cooling line. C 34 n. SQP • . . . and who designs what: – PP 0 Boards [CERN] – Power and Readout Bundles [CERN] – Connector to the Opto. Box (Conn. Board) [CERN] – – DBM Structure Boiling Channel Thermal coupling DBM Flex D. Giugni [Toronto] [? ] DBM Interfaces Meeting 2011 -09 -28 5

Prototypes Production Plan n. SQP’s • Hope to get from this meeting the green light for the design: – Interfaces (at PP 0 and at PP 1). • Cooling fittings location • Cooling coupling • Connectors • Boards – Services functionality. • Wires type, number and connectivity. • Procurement – – Wires, Shield, Braids (4 wks leading time), PP 0 boards (6 wks) IBL Connector Board (4 wks) AXON Connector and pinout (? ) D.

Prototypes Production Plan (2) n. SQP’s • Middle November can start producing the fist full DBM harnesses. • Production time (bundling and soldering) ~2 wks • If something goes wrong there is time for a second try before Xmas D. Giugni DBM Interfaces Meeting 2011 -09 -28 8
