Position Title:

ARIEL stable atom source research student 

Name of Project:

Stable "Mass Marker" Atom Sources for ISOL Targets 


The capability to introduce a controlled supply of atoms of an element of interest to ARIEL targets/ion sources is a development priority. Additionally, the integration of this development into ISAC targets could provide both valuable input for their development and support ongoing ISAC operation. This capability has proven to be invaluable for target/ion source development (TISD), molecular beam formation, ion beam tuning and efficiency investigations at a number of ISOL facilities worldwide. The atom sources, commonly termed “mass markers” are typically resistively heated refractory metal capillaries. They must survive the thermally and radioactively harsh environments of ISOL targets and provide a stable atom supply when required.


- Mechanical design to integrate the atom sources into the ARIEL target design.
- Electrical integration of the resistively heated atom sources.
- Thermal simulations to determine the heating and shielding requirements using software such as COMSOL multiphysics or ANSYS.
- Collation of element specific heating requirements based on vapour pressures.
- Testing and characterization of prototype systems.

Skills learned during this work experience:

- Complex multiphysics simulation experience using software like COMSOL, ANSYS
- Analysis skills with which to interpret simulation results
- Experience with CAD-type mechanical design environment
- Mechanical and electrical design experience with skilled engineers
- Hands-on experience with state-of-the-art test stands


3rd or 4th year Mech.Eng. / Eng.Phys. / Phys. student wanted for two work terms. Requires some familiarity with thermal simulations and hands-on lab experience. Knowledge of mechanical design would be an asset.

Shiftwork required:


Period of work:

May - Aug 2018 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.
