Introduction
• Working on getting summaries and info out of tkLayout for services
• Under development (not debugged, not updated)
• Used as reference among detector, electronics and mechanics designers ,
to assist communication and decision-making
• Not to compare ‘1-1’ now but to trigger conversation for comparison
(offline).
• Code can be used for different pixel geometry configurations w/o
modification
• Contents of the talk:
– First part : introducing the new summary tab added and pointing out what needs
to be updated / discussed
– Second part : some useful plots

Three identical tables
(one after the other):
Barrel, FPIX1, FPIX2

Reshuffling
information that
was already in the
geometry tab
• 12 rods of 9 modules of 1x2 (L1,L2) or 2x2(L3,L4)
• 25x100 used along all layers

Barrel Table Part #2:
Powering description
[X] SP RULES BROKEN
BY GEOMETRY
Incompatible with
chip capabilities
•
Reminder of “SP rules” as summarised by Charles [July’s tracker week,
https://indico.cern.ch/event/548644/]
– Maximum length of SP chain: 8clusters
– BPIX rods/FPIX Dees/FPIX rings/FPIX rings side independent from each other
– SP chains can be made of “clusters” that can be modules 1x4 or 2x2 with chips on
module parallel powered or Two Modules of 1x2 each, parallel powered.
• The reason why is that for the moment there is no protection foreseen and
only the failure scenario of 1 out 4 chips (meaning the rest will need to carry
32%Ichain extra current) has been studied. There is no guarantee that a chip
11
can carry 100% extra current.
E-links info &
Summary of Services weights
[mm]
• Info for GBT/#links/speed etc
• Summary of services weights [gr] per layer (per Z-end)
• Other information that could be useful?
12
FPIX example summary table
[X] Differences on
services info:
• SP, Cooling and
HV are distributed
homogeneously
on disks. No ring
information.
• TWP per ring info
13
Part #2
• Services plots for OT_Tilted_362_200_Pixel4021
• Currently these plots are not generated
automatically
• Working on making another tab with this kind of
plots
14
Length of TWP [mm] per Z end
Twisted Pairs Length distribution
• Although L4 at higher radius, the length till the optoconversion dominates.
• Min ~400cm and max ~550cm BPIX TWPs.
• Very short distances for FPIX TWPs.

Converge on number for power+ chains
Update ROC Power numbers
Fill in FPIX info for services
Add Fiber info in the summary table
• Currently only on the csv summary
– Radiation length plots
• Currently manually
– Debug and release this version of the code
