Undergraduate Student Research Positions with the ATLAS Toronto Group in 2017

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 makea discovery this summer!

• Inner Tracker Upgrade Readout Electronics:

  

  The ATLAS collaboration 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 associated readout electronics must be more radiation-tolerant and run at much higher data transfer speeds. In Toronto we are 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 or participating in the project through the Woodsworth Science Abroad program, will be able to join our efforts in understanding how the ITk readout electronics responds to neutron and ionizing radiation dosage. This work will use intense radioactive sources and particle beams at CERN.

• ATLAS Detector Simulation:

  
  Upgrades to the ATLAS detector for 2023 include modifying the readout system for the current liquid argon calorimeter. This work involves simulation of the existing forward calorimeter in the higher-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 ITk. 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.

• Pixel Diamond Beam Monitor:

  
  During the 2013-14 LHC machine stop, ATLAS augmented its beam monitoring and safety system to include a series of diamond pixel tracking telescopes. They saw first beam in 2015 and 2016. We are continuing to work to optimise their performance. There will be a number of self-contained projects associated with this, that would be suitable for undergraduate research students.
