Undergraduate Student Research Positions with the ATLAS Toronto Group
The University of Toronto ATLAS group
has several summer student positions open
to USRA recipients and other students for summer 2018. The group comprises six faculty
Trischuk), four postdoctoral fellows and approximately 18 graduate students.
The ATLAS experiment at the Large Hadron Collider (LHC) at CERN, in Geneva Switzerland,
is studying the very highest collision energies ever observed in the lab.
The most exciting discovery to date has been the observation
of a new particle at 125 GeV, with properties consistent with the Standard
Model Higgs boson.
We will continue increasing the size of our dataset in 2018 and analyzing it for insights
Summer students will be working with us in projects involving data analysis and
advanced instrumentation development.
Perhaps something un-expected will emerge from the data-taking while you're looking!
Project topics and potential supervisors include:
Physics Studies for ATLAS:
Simulation of physics events in the ATLAS detector and development of
data selection and analysis techniques for specific physics channels.
The LHC has been colliding
protons at 13 TeV since 2015 and the group is involved in analysis of channels
including multiple W and Z bosons, top quarks and Higgs bosons.
There will be opportunities to look at some of the very newest data.
Who knows, perhaps we will make a discovery this summer!

Inner Tracker Upgrade Sensor and Readout Electronics R&D:
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. As part of this project we will be testing and characterizing miniature silicon sensors that have been irradiated in a reactor.
This is to simulate how the real sensors will behave after being exposed to radiation from the LHC beams. We use a probe station, a Strontium-90 source, and a laser system at low temperature to study the sensors.
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.
Contact: Bob Orr.
At CERN a student with, for example, an
IPP summer fellowship or
participating in the project through the
Woodsworth Science Abroad program, will be
able to join our efforts in understanding how the prototype ITk readout electronics
responds to neutron and ionizing radiation dosage.
This work will use intense radioactive sources and particle beams at CERN.

The ATLAS Toronto group is also involved in the development of a simulation
of the ITk detector, and studies of its performance.
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 and predict the performance
of the tracking system.
ATLAS Detector Simulation:
Upgrades to the ATLAS detector for the High-Luminosity LHC era, starting in 2026,
also include the design and construction of a
new readout system for the existing liquid argon calorimeter.
The ATLAS Toronto group is involved in a number of ways, including the
development of the signal processing techniques that will be used to extract the
energy and timing of calorimeter signals, using digital filtering techniques.
This position involves simulation work related to these studies.
Some prior knowledge of electronics and signal processing techniques would be advantageous.

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