3. Strip Tracker Components
Attempted to contact as many as possible to get outline/ideas for the strip community’s plans for production numbers & database preferences
Based on LOI layout
5 layers, stubs, etc.
However LOI is “worst case” scenario in terms of no of parts
All other cases would see reduction in part numbers
List is also incomplete
Other necessary components for the build
GBT’s, Fibre optics, DCDC/SP boards, HV switches etc.
And does not detail 1MHz Readout designs
New hybrids, multiplexing chips….

Will use these numbers as the basis for the following build numbers
Of course these numbers will change once the yield estimates become more fixed

16. What do we want to record?
Currently .eps/.ps files produced from hybrids and module scans are ~1.2Mb
Strobe delay + Threshold scan + Noise Occupancy scan ~= 4Mb/object
~54k Objects* = ~ 216 GB
*this is just hybrids and modules and doesn’t include dat/txt files

17. What do we want to record?
We would like to trace "service" material
Glues
Jigs
Test frames
Test setups
From EC database experience
“We were able to trace the number of components available, where we could expect shortage of them, etc.”
“This saved us in a couple of occasions. It also helped to monitor the learning slope of the production and to detect weak points in the chain…”

18. Visual Inspection - Photos
Has been a request to have the ability to add photos
Trace defects/visual inspection stage through
Sensor -> Hybrid -> Module -> Stave/Petal assembly
~ 54k objects (hybrids + modules) x 3 photos
= 150k photos
This an issue?

19. RFiD - Barcodes
Strips community have began to integrate RFiDs onto hybrids.
The current design for the ABC130 Barrel Hybrids use LXMS31ACNA-010
EPC memory (Electronic Product Code): 240 bit unique device ID
User memory: 512 bits
TID: 64 bits, unique address assigned by the IC manufacturer
Scanning of RFiDs could also allow tracing of components throughout the build project
Beginning to think about linking RFiD IDs of hybrids to any future database naming conventions
Meeting on ITk production databases

20. Naming Conventions Still at early stages for Barrel
More developed for Endcap due to greater number of Hybrids/Modules (next slide)
So far only gone as far as convention for actual objects
Not where it was made/location etc.
Meeting on ITk production databases

21. Naming Conventions
For EC, numbering scheme to be implemented, e.g. R0H1S0 (Ring 0, Hybrid 1, Sensor 0).

22. Summary
Hopefully we have been able to gather information that will help for
Components
Max part numbers
Input to database
Developing all the time
We have (at present ) have no input regarding “type of database”
Feedback seems to be the previous SCT database was very good
