Canada's National Laboratory for Particle and Nuclear Physics
Summer 2018 job posting
Job number TR18-2-37

Position Title:

Beam Optics and Recommissioning of the M11 beam channel 

Name of Project:

Beam Optics and Recommissioning of the M11 beam channel 


The M11 beam channel at TRIUMF is a system comprising dipole magnets to bend subatomic particles, and quadrupole and sextupole magnets to focus these particles. It is used to select the momentum of a beam of secondary particles (pions, muons and positrons / electrons) produced by the proton beam of the TRIUMF cyclotron, and directs these particles into a beam area where the experiments are located. Formally, the effect of a set of bending and focusing magnets on charged particles is almost identical to that of a system of prisms and lenses in optics, hence we refer to the "ion-optics" properties of the beam channel.

This beam channel will be reconfigured in the period January-March 2018 to direct particles to the east rather than to the west. This redirection requires a computational study of the ion-beam optics of this new configuration to optimize the flux of particles delivered, and experimental measurements of the beam properties in this new configuration.


1. The student will assist with the computational study of the beam optics, using TRANSPORT, TRANSOPTR and other particle beam transport programs.

2. The student will assist in measuring the beam size, particle composition, and beam flux of the delivered beam particles at various momentum settings.

3. The student will revise the user's manual for the M11 beam channel.

Skills learned during this work experience:

- ion-beam optics of bending and focusing systems for beams of charged particles from an accelerator

- matrix techniques for describing and calculating the bending and focusing properties of dipole and quadrupole magnets

- techniques for optimizing an ion-beam optical system

- understanding how subatomic particles interact when they pass through matter

- techniques of detecting and characterizing subatomic particles (pions, muons, electrons/positrons) produced by an accelerator


Physics / engineering physics / electrical engineering student with an interest in the optics of charged particle beams; good ability in written English and good presentation skills
