The ATLAS experiment is replacing it's inner detector
in 2023 with a new Inner Tracker (ITk).
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. There is
the possibility that a student will have the opportunity to work in the
Celestica company micro-electronics facility.
we will be testing sensor assemblies in the department using a beta irradiation
facility.

At CERN a student with, for example, an IPP summer fellowship will be
able to join our efforts in understanding how the tracker Application
Specific Integrated Circuits (ASICs) respond to neutron and ionizing
radiation dosage. This work will use intense radioactive sources and
particle beams at CERN.

ATLAS Detector Simulation:
Planning for upgrades to the ATLAS detector in 2023 includes upgrades to the
current liquid argon calorimeter, which will required a modified readout system
for this high-luminosity LHC phase.
Overall this work involves simulation of the existing forward
calorimeter in this high-rate environment, where the response is expected to be degraded, as
well as simulations of proposed detector upgrade scenarios.
A separate project involves developing a more efficient calorimeter simulation for the
existing instrumentation.

The Toronto group is also involved in the design and simulation of the new Inner Tracker.
This new tracker, the ITk, will have to function in an environment where the LHC
beams will create up to 200 collisions at one time.
We will be working to better understand and improve the simulation
software the ATLAS collaboration has developed to model the ITk.

We will consider applications from students not holding a USRA
award, but USRA recipients are given priority. There may be the
opportunity for some of these students to spend at least part of the
summer at CERN.
