Canada's National Laboratory for Particle and Nuclear Physics
Summer 2018 job posting
Job number TR18-2-16

Position Title:

Muon Beamline Simulationist using TRANSOPTR and G4Beamline/GEANT4. 

Name of Project:

Simulating, designing/optimizing Muon Beam delivery on M9H and M9A. 


The M9A and M9H channels at TRIUMF deliver a surface muon beam and a decay beam respectively. This project will use TRANSOPTR and GEANT4/G4BeamLine to simulate the beamlines. The goal is to optimize tuning strategies for M9A and design/optimize the beam line configuration for transversely spin polarized muons in M9H. Since in the latter case, muons are created by pion-decay within a 5T solenoid, the beamline becomes a spin-polarization analyzer prior to delivering the beam to an experiment. Optimizing the "analyzing power" of the muon beam simulation then becomes a significant issue in the design.


Learn TRANSOPTR, G4Beamline/Geant4. Simulate the M9 decay and surface muon channels. Learn how to run optimization code using the above programs. Help select an optics design for M9H to optimize transversely muon spin polarized transmission.

Skills learned during this work experience:

Relativistic Particle Mechanics. i.e. High Energy beam dynamics during weak decay.

The Muon Spin Rotation (MuSR) technique.
TRANSOPTR beam line transport program (which is written in Fortran, i.e. see
The G4Beamline/Geant4 beamline simulation tools.
Optimization coding.


Computer Science, Engineering Physics, Physics, Chemistry, Experience with simulations, Root, knowledge of Fortran
Required: Computational coding skill, Basic Computer languages, i.e. C+/C++, Linux, Python. Desire to learn about particle beam lines and relativistic decay.

Shiftwork required:


Period of work:

At least 4 months with extension possible with possible 4-month extension  
Salary is commensurate with academic progress and previous relevant work experience, and ranges from $ 2080 to $ 2800 per month plus 4% vacation pay.
