for 100h at 40°C
• For mass-testing a crate system was
designed
• Allows to test 36 hybrids at 640Mbit/s
readout speed
Design: Ashley Greenall
J.Taylor Liverpool HEP Xmas Meeting 20/12/19 8
Automatic visual inspection of hybrids
Original Annotated

automate the process

J.Taylor Liverpool HEP Xmas Meeting 20/12/19 10Next steps
• Strip Module Final Design Review has been passed (September 2019) with significant contributions from Liverpool
• Passing FDRs allow progression to pre-production
• Pre-Production:
– Produce 5% of total number of ITk modules for site qualification and ramp-up to production
– First sensors to be delivered January 2020
– First hybrids to be build at Liverpool in July 2020
– Module site qualification to be completed: November 2020
– Module Production Readiness Review: December 2020
– Module pre-production to be completed: 2021
– First staves due to arrive at CERN c2022, work at CERN beyond current production grant - completion bid to be
submitted during 2020, opportunity for Liverpool?
If something is expensive and hard to build, why not
set it on fire?

A lot of work from many
dedicated people, looking
forward for an intense 2020,
also with further contributions
from our academics :)
Merry Christmas!
