The ATLAS experiment is replacing its inner detector
with a new Inner Tracker (ITk), with the new device in place by 2026.
The collision intensity and radiation background will mean that
both the particle sensors and their associated readout electronics must
be more radiation-tolerant and run at much higher data
transfer speeds. In Toronto we will be building prototype silicon
sensor assemblies in association with Celestica, a company specializing in the
fabrication of high-density electronics,
One, or more, students involved with this project will help to modify our sensor testing setup, take data with the miniature sensors, and help to understand the interesting
physics of these devices. There is plenty of scope for electronics, hardware, software and most of all, thinking. All in the environment of a small self-contained experiment.
The picture opposite shows one of our first complete silicon sensor modules, with its associated readout chips.

At CERN a student with, for example, an
IPP summer fellowship will be able to join our efforts in understanding how the prototype ITk readout electronics
responds to neutron and ionizing radiation dosage.
We will be focusing on tests of the ``production'' versions of the readout chip, the so-called ABCStar.
